Deepwater Hydrocarbon Exploration in China Seas: Yesterday, Today and Tomorrow

Zhi-gang Zhao,Hai-zhang Yang,Wu Tang,Shi-xiang Liu

《工程管理前沿（英文）》 2016年 第3卷 第4期   页码 390-395 doi: 10.15302/J-FEM-2016059

摘要： Deepwater area has been one of the hottest areas in the global hydrocarbon exploration. However, deepwater hydrocarbon exploration in China started late and mainly concentrated in the South China Sea (SCS) with low level of researches. Although there are some achievements, there are even more challenges. For this reason, this paper reviewed the history of deepwater exploration in China Seas and summarized the current exploration situation. The future directions of deepwater hydrocarbon exploration mainly consist of five aspects: establishing key technology system of complex structure and reservoir seismic acquisition and processing in deepwater areas of SCS, clarifying the development mechanism of high quality source rock and establishing matching assessment technology, studying the formation conditions of favorable reservoir and creating reservoir identification technology, improving accumulation theory of large and medium-sized oil and gas field of deepwater, deepening the researches of petroleum geology conditions of middle and south part of SCS. Simultaneously, the concept of portfolio should be utilized in the exploration process, with economic benefits considered. These understandings will help guiding the future deepwater hydrocarbon exploration in China Seas.

Multi-scale evaluation of river health in Liao River Basin, China

Fei XU, Yanwei ZHAO, Zhifeng YANG, Yuan ZHANG

《环境科学与工程前沿（英文）》 2011年 第5卷 第2期   页码 227-235 doi: 10.1007/s11783-010-0219-9

摘要： Previous studies on river health evaluation mainly focused on characterizations at a river-corridor scale and ignored the complex interactions between the river ecosystem and other components of the river basin. Based on the consideration of the interactions among rivers, associated river basin and habitats, an assessment framework with multi-scale indicators was developed. An index system divided among these three scales to characterize the health of river ecosystems in China’s Liao River Basin was established. Set pair analysis was applied to integrate the multi-scale indicators and determine the health classes. The evaluation results indicated that the rivers in the western and eastern zones of the Liao River were classified as sick, and rivers in the main stream of the Liao and Huntai rivers were classified as unhealthy. An excessive level of disturbances, such as large pollution loads and dense construction of water conservation projects within the river basin, were the main causes of the river health deterioration.

摘要： Understanding the trends in PM levels is essential for formulating clean air plans. This paper analyzes PM data from various published sources for the years 2000 to 2010 in the Pearl River Delta Economic Zone (PRDEZ). The long-term variation in PM mass concentration is analyzed. Results show that PM , organic carbon (OC), elemental carbon (EC), and show a similar trend, increasing before 2005 and then decreasing slightly. The annual average PM concentration ranges from 49.1 μg·m in 2000 to 64.3 μg·m in 2010, with a peak of 84.1 μg·m in 2004. None of these 11 years meets the new National Ambient Air Quality standard (NAAQS) for PM (35 μg·m ). Overall average concentrations of OC, EC, and are 13.0, 6.5, and 11.8 μg·m , respectively. and respectively have concentrations of 1.5 μg·m and 2.9 μg·m in 2000 and 6.4 μg·m and 5.3 μg·m in 2010, with a statistically significant average annual trend of+ 0.2 μg·m ·yr and+ 0.1 μg·m ·yr . In certain geographic regions, OC and EC contribute most of the PM , while in other regions secondary water-soluble ions are more important. In general, OC and are the dominant components of PM , contributing 20.6% and 18.6%, respectively. These results provide, for the first time, a better understanding of the long-term PM characteristics and trends, on a species-by-species basis, in the PRDEZ. The results indicate that PM abatement needs to prioritize secondary species.

Problems of Syrdarya river basin management

Serdar EYEBERENOV, Baijing CAO, Fengting LI

摘要： Prior to independence, Central Asian countries were closely interconnected through the regional management incorporating water, energy, and food sectors. This approach, supported by the central government of Union of Soviet Socialist Republics (USSR), functioned effectively – meeting the needs of both upstream and downstream countries. However, after independence, Central Asian countries started prioritizing their own economic development policies without due account to regional concerns such as joint use of water resources, leading to instability. In this study, the case of Syrdarya basin was investigated to show how such strategies create tension in the region, since primary focus is given to national interests, without consideration for regional problems. To address this issue, an integrated approach to incorporating water, energy, and agriculture is needed. It is suggested that a single sector approach on water alone does not lead to stability, and a multi-sectoral approach is necessary to ensure sustainable development. Countries sharing benefits from the river have to be responsible for costs of operation and maintenance of the water facilities.

Integrated river basin management in rapidly urbanizing areas: a case of Shenzhen, China

Lei LIU, Xiaoming MA

《环境科学与工程前沿（英文）》 2011年 第5卷 第2期   页码 243-254 doi: 10.1007/s11783-010-0276-0

摘要： The rapid urbanization of China is causing a burden on their water resources and hindering their sustainable development. This paper analyzes effective methods to integrated river basin management (IRBM) using Longgang River basin of Shenzhen as an example, which is the city with the fastest rate of urbanization in China and even the whole world. Over the past 20 years, China has undergone a population boom due to the increase of immigrant workers and rapid development of labor-intensive industries, which led to the sharp increase of water consumption and sewage discharge. However, the construction of the water infrastructure is still lagging far behind the environmental and social development, with only 32.7% of sewage in the district being treated. Currently, every water quality indicator of the Longgang River basin was unable to meet the required corresponding environmental standards, which further aggravated the water shortages of the region. Thus, an analytical framework is proposed to address the IRBM of the study area. The problems with the current management system include the lack of decentralization in decision-making, lack of enforcement with redundant plans, weak management capacity, financial inadequacy, and a poor system of stakeholder participation. In light of the principles of IRBM and the situation of the region, corresponding measures are put forward, including an increase of power given to sub-district offices, fewer but more feasible plans, capacity building among stakeholders, a combination of planning and marketing for overcoming financial inadequacy, and profound reform in the public participation system. The framework and institutional suggestions could inform similar processes in other representative river basins.

Zifeng WANG, Min SHAO, Liangfu CHEN, Minghui TAO, Liuju ZHONG, Duohong CHEN, Meng FAN, Yang WANG, Xinhui WANG

《环境科学与工程前沿（英文）》 2016年 第10卷 第5期 doi: 10.1007/s11783-016-0853-y

摘要： Spatial and temporal trends of the typical pollutants in PRD viewed from space. Comparisons of the satellite retrievals with the collocated in situ data are given. Among different MCs, the control measures applied in PRD are the most effective. The unique HCHO trends imply significant contribution from the biogenic origins. The Pearl River Delta (PRD) is one of the most industrialized, urbanized and populated regions in China, and thus has been long suffering from severe air pollutions. Space data provide a unique perspective for investigating the atmospheric environment at a regional scale. By utilizing multiple satellite retrievals from 2005 to 2013, this study presented, for the first time, the spatial patterns and temporal trends of typical air pollutants over PRD and its vicinity. As viewed from space, aerosol optical depth (AOD), NO2 and SO2 all had their higher values at the central part of PRD, and showed clear descending gradients as moving to the outskirt of this region. As to the inter-annual variation, all these pollutants had decreasing trends in PRD during the study period, which generally agreed with the relevant in situ measurements. However, the satellite retrievals differed from ground measurements when addressing NO2 and SO2 in the vicinity of PRD. This work also provides the inter-comparison among PRD and three other metropolitan clusters in China: PRD had relatively high AOD, moderate NO2 and low SO2 levels, and it was the only region achieving the effective reduction of NO2 and SO2 during last decade. Unlike the previous three pollutants, HCHO observed by satellite showed very special patterns: it had a relatively homogeneous spatial distribution over both of PRD and its vicinity, and presented an opposite increasing trend from 2005 to 2010. Moreover, PRD had the highest HCHO level among all the metropolitan clusters, hinting a considerable contribution of biogenic origins of HCHO in PRD.

Research on the ecological compensation standard of the basin pollution control project based on evolutionarygame theory and by taking Xiangjiang River as a case

Dongbin HU, Huiwu LIU, Xiaohong CHEN, Yang CHEN

《工程管理前沿（英文）》 2019年 第6卷 第4期   页码 575-583 doi: 10.1007/s42524-019-0044-1

摘要： Ecological compensation is a new resource and environment management model. As one of the main areas for implementing ecological compensation policies, basin ecological compensation has become an important measure for encouraging basin pollution control projects and improving the quality of regional economic development. By applying the basic game analysis of evolutionary game theory and building an evolutionary game model with a “reward–punishment” mechanism, this paper compares the interest-related decision-making behaviors of the upstream and downstream stakeholders of basin ecological compensation. By using data on the water quality of Xiangjiang River Basin, this paper calculates the rewards and penalties in different intervals by building a parametric regression mathematical model and employing the local linear regression method. Results show that a decline in water quality should be fined RMB 925500 yuan, an improvement in water quality should be awarded RMB 1227800 yuan, and a deteriorating water quality should be severely fined RMB 5087600 yuan.

Photochemical indicators of ozone sensitivity: application in the Pearl River Delta, China

Lyumeng Ye,Xuemei Wang,Shaofeng Fan,Weihua Chen,Ming Chang,Shengzhen Zhou,Zhiyong Wu,Qi Fan

《环境科学与工程前沿（英文）》 2016年 第10卷 第6期 doi: 10.1007/s11783-016-0887-1

摘要： The distribution of NO - and VOC-sensitive regimes in the PRD are identified. The effectiveness of six popular chemical indicators for discriminating O sensitivity regimes is evaluated. Threshold levels for HCHO/NO , H O /HNO , O /NO , O /NO , O /HNO were derived and verified. The indicators H O /HNO and H O /NO performed best and maintained relatively stable threshold levels. Surface O production has a highly nonlinear relationship with its precursors. The spatial and temporal heterogeneity of O -NO -VOC-sensitivity regimes complicates the control- decision making. In this paper, the indicator method was used to establish the relationship between O sensitivity and assessment indicators. Six popular ratios indicating ozone-precursor sensitivity, HCHO/NO , H O /HNO , O /NO , O /NO , O /HNO , and H O /NO , were evaluated based on the distribution of NO - and VOC-sensitive regimes. WRF-Chem was used to study a serious ozone episode in fall over the Pearl River Delta (PRD). It was found that the south-west of the PRD is characterized by a VOC-sensitive regime, while its north-east is NO -sensitive, with a sharp transition area between the two regimes. All indicators produced good representations of the elevated ozone hours in the episode on 6 November 2009, with H O /HNO being the best indicator. The threshold sensitivity levels for HCHO/NO , H O /HNO , O /NO , O /NO , O /HNO , and H O /NO were estimated to be 0.41, 0.55, 10.2, 14.0, 19.1, and 0.38, respectively. Threshold intervals for the indicators H O /HNO , O /NO , O /NO , O /HNO , and H O /NO were able to identify more than 95% of VOC- and NO -sensitive grids. The ozone episode on 16 November 16 2008 was used to independently verify the results, and it was found that only H O /HNO and H O /NO were able to differentiate the ozone sensitivity regime well. Hence, these two ratios are suggested as the most appropriate indicators for identifying fall ozone sensitivity in the PRD. Since the species used for indicators have seasonal variation, the utility of those indicators for other seasons should be investigated in the future work.

A holistic approach for evaluating ecological water allocation in the Yellow River Basin of China

YANG Zhifeng, CUI Baoshan, CHEN He

《环境科学与工程前沿（英文）》 2007年 第1卷 第1期   页码 99-106 doi: 10.1007/s11783-007-0019-z

摘要： The characteristics and sustainable management of water resources on a basin scale require that they should be managed using a holistic approach. In this study, a holistic methodology called the holistic approach in a basin scale (HABS) is proposed to determine the ecological water requirements of a whole basin. There are three principles in HABS. First, ecological water requirements in a basin scale indicate not only the coupling of hydrological and ecological systems, but also the exchange of matter and energy between each ecological type through all kinds of physical geography processes. Second, ecological water requirements can be divided into different types according to their functions, and water requirements of different types are compatible. Third, ecological water requirements are related to a multiple system including water quality, water quantity, and time and space, which interact with each other. The holistic approach in a basin scale was then used in the Yellow River Basin and it suggested that 265.0 × 10 m of water, 45% of the total surface water resources, should be allocated to ecological systems, such as rivers, lakes, wetlands and cities, to sustain its function and health. The ecological water requirements of inside river systems and outside river systems were respectively 261.0 × 10 and 3.65 × 10 m.

Efficiency Are Characteristic of Ecological Restoration Towards High-Quality Development in the Yellow RiverBasin, China

Yang Yu,Ting Hua,Liding Chen,Zhiqiang Zhang,Paulo Pereira,

《工程（英文）》 doi: 10.1016/j.eng.2023.07.012

摘要： Globally, vegetation has been changing dramatically. The vegetation–water dynamic is key to understanding ecosystem structure and functioning in water-limited ecosystems. Continual satellite monitoring has detected global vegetation greening. However, a greenness increase does not mean that ecosystem functions increase. The intricate interplays resulting from the relationships between vegetation and precipitation must be more adequately comprehended. In this study, satellite data, for example, leaf area index (LAI), net primary production (NPP) and rainfall use efficiency (RUE), were used to quantify vegetation dynamics and their relationship with rainfall in different reaches of the Yellow River Basin (YRB). A sequential regression method was used to detect trends of NPP sensitivity to rainfall. The results showed that 34.53% of the YRB exhibited a significant greening trend since 2000. Among them, 20.54%, 53.37%, and 16.73% of upper, middle, and lower reach areas showed a significant positive trend, respectively. NPP showed a similar trend to LAI in the YRB upper, middle, and lower reaches. A notable difference was noted in the distributions and trends of RUE across the upper, middle, and lower reaches. Moreover, there were significant trends in vegetation–rainfall sensitivity in 16.86% of the YRB’s middle reaches—14.08% showed negative trends and 2.78% positive trends. A total of 8.41% of the YRB exhibited a marked increase in LAI, NPP, and RUE. Subsequently, strategic locations reliant on the correlation between vegetation and rainfall were identified and designated for restoration planning purposes to propose future ecological restoration efforts. Our analysis indicates that the middle reach of the YRB exhibited the most significant variation in vegetation greenness and productivity. The present study underscores the significance of examining the correlation between vegetation and rainfall within the context of the high-quality development strategy of the YRB. The outcomes of our analysis and the proposed ecological restoration framework can provide decision-makers with valuable insights for executing rational basin pattern optimization and sustainable management.
