Qiang WANG, Lijuan ZHAO, Xuekun FANG, Jianhua XU, Yifan LI, Yehong SHI, Jianxin HU

《环境科学与工程前沿（英文）》 2013年第7卷第1期页码 10-18 doi: 10.1007/s11783-012-0458-z

摘要： Chlordane (1,2,4,5,6,7,8,8-octachloro-3a,4,7, 7a-tetra-hydro-4,7-methanoindane) is one of organochlorine pesticides (OCPs) which has been listed as one of the persistent organic pollutants (POPs) to be reduced and finally eliminated in the Stockholm Convention on Persistent Organic Pollutants, because of its great persistence, toxicity, bio-accumulation and long-range transport potential. It is critical to create a national chlordane usage inventories for China to compile chlordane emission inventories, which is helpful for carrying out risk assessments and other researches related to chlordane in China. The annual data of chlordane usage was calculated and modified in accordance with the reported annual production of chlordane which was caculated on the basis of the termite distribution, the data of chlordane usage rate and the annual new construction area (NCA). With the help of Geographic Information System, the usage data of this NCA were allocated to a grid system then, with a 1/4° longitude by 1/6° latitude resolution and a size for each grid cell of approximately 25 km by 25 km. Between 1988 and 2008, the total usage of chlordane in China was 2745 t, accounting for approximately 80% of the production in the same period. Zhejiang Province was the largest consumer of chlordane in China, whose usage adds up to 980 t, greatly exceeding other provinces/regions, followed by Jiangsu Province (534 t) and Sichuan Province (428 t). The region with the least usage of chlordane was Beijing. Provinces of Guizhou, Henan and Hebei did not use any chlordane, even though termites had occurred in these provinces. Gridded usage inventories showed that the intensive use of chlordane was concentrated in the south-east part of China, Yangtze River Delta and Pearl River Delta in particular. The satisfaction of the inventories was supported by the consistence between the estimated data of annual usage and the reported annual production of chlordane, and by the consistence between distribution pattern of chlordane’s usage and ambient air concentration.

Impact of introducing a herb pasture area into a New Zealand sheep and beef hill country farm system:

Cécile DURANTON, Cory MATTHEW

《农业科学与工程前沿（英文）》 2018年第5卷第1期页码 87-97 doi: 10.15302/J-FASE-2018202

摘要： New Zealand is well known for export of meat and dairy products from low cost pastoral systems. These farm systems are continually evolving for increased efficiency, in part through the use of metabolic energy modeling tools by farmers and farm consultants to explore alternative farm system configurations and identify new efficiencies. One recent innovation is the introduction of a herb pasture area, such as plantain. We used metabolic energy modeling to quantify seasonal feed flows in two successive years in a New Zealand hill country farm system, and to analyze the impact of the introduction of an area of plantain. Models employed were a self-built Microsoft Excel spreadsheet and a commercial New Zealand farm systems modeling package, FARMAX. Herbage production, animal performance and financial results for a base farm scenario created from the average of survey data for hill farms in the southern North Island, and the same farm with 10% and 20% of the area in plantain for the years 2010–2011 and 2011–2012 were modeled. The self-built model performed similarly to the commercial model. The system configuration of the base farm stockpiles surplus autumn feed for release to animals in winter and also incorporates flexibility that confers resilience to interannual weather variation through varying dates animals are purchased or sold. The introduction of an area of plantain was predicted to increase herbage production, animal performance and financial returns. The predicted benefit was higher for the year 2010–2011 where a drought occurred in summer than for the following year with higher summer rainfall. This demonstrates the profitability of introducing a plantain area to New Zealand hill farm systems, and suggests plantain will assist to mitigate adverse effects of warmer and drier summer conditions associated with current climate change trends.

Self-centring segmental retaining walls—A new construction system for retaining walls

《结构与土木工程前沿（英文）》 2021年第15卷第4期页码 980-1000 doi: 10.1007/s11709-021-0737-5

摘要： This paper reports on an experimental study on a new self-centring retaining wall system. Four post-tensioned segmental retaining walls (PSRWs) were experimentally tested. Each of the walls was constructed using seven T-shaped concrete segments with a dry stack. The walls were tested under incrementally increasing cyclic lateral load. The effect of the wall height, levels of post-tensioning (PT) force, and bonded versus unbonded condition of PT reinforcement on the structural behavior of the PSRWs was investigated. The results showed that such PSRWs are structurally adequate for water retaining structures. According to the results, increasing the wall height decreases initial strength but increases the deformation capacity of the wall. The larger deformation capacity and ductility of PSRW make it a suitable structural system for fluctuating loads or deformation, e.g., seawall. It was also found that increasing the PT force increases the wall’s stiffness; however, reduces its ductility. The residual drift and the extent of damage of the unbonded PSRWs were significantly smaller than those of the bonded ones. Results suggest that this newly developed self-centring retaining wall can be a suitable structural system to retain lateral loads. Due to its unique deformation capacity and self-centring behavior, it can potentially be used for seawall application.

《中国工程科学》 2013年第15卷第6期页码 25-29

摘要：

上海肩负着建设“四个中心”的重任，同时又面临着众多的发展瓶颈，其中土地资源的短缺是制约上海发展的重要因素。横沙岛是一个集“区位、土地、岸线、航道”等众多优势资源于一身的区域，其可成陆的土地面积约为480 km2，可形成的岸线近100 km，同时利用其东侧直接面向大海的优势，有建设深水大港的条件。横沙新城的建设即可突破城市瓶颈，再造第二个“浦东”，为未来上海的发展提供广阔空间。

秦巴山脉区域跨域性政府协同治理体系构建研究

袁晓军,温娜,张近乐

《中国工程科学》 2020年第22卷第1期页码 50-55 doi: 10.15302/J-SSCAE-2020.01.005

摘要：

区域性问题的解决依赖于同区域内各个地方政府之间的协同合作，而秦巴山脉区域内的多头治理以及政府间缺乏政策协调的现状，已经明显制约了区域经济建设、生态保护的可持续发展。针对秦巴山脉区域内各地方政府目前协同合作中表现出的缺乏系统规划和全局思路、合作程度较浅以及合作领域较窄等问题，本文阐述了组织间合作网络理论，分析了长江流域综合治理的成功经验，据此提出了构建秦巴山脉区域三级协同治理体系的总体思路。研究建议：进一步加强秦巴山脉区域的统筹规划、在国家层面设立专门机构来落实协同治理的“协调人”角色、发挥区域性重点建设工程对协同治理的引领和实践作用、推动区域内地方政府间的人员交流和换位思考。相关研究可为秦巴山脉区域建立区域政府协同治理机制、提高政府治理水平提供参考。

Can floor-area-ratio incentive promote low impact development in a highly urbanized area?

Ming Cheng, Huapeng Qin, Kangmao He, Hongliang Xu

《环境科学与工程前沿（英文）》 2018年第12卷第2期 doi: 10.1007/s11783-017-1002-y

摘要： As an environmental friendly measure for surface runoff reduction, low impact development (LID) has been applied successfully in urban areas. However, due to high price of land and additional expense for LID construction in highly urbanized areas, the developers of real estate would not like to proceed LID exploitation. Floor area ratio (FAR) refers to “the ratio of a building’s total floor area to the size of the piece of land upon which it is built.” Increasing FAR indicates that the developers can construct higher buildings and earn more money. By means of awarding FAR, the developers may be willing to practice LID construction. In this study, a new residential district is selected as a case study to analyze the trade-off between the runoff reduction goal achieving by LID practices and the incentive of awarding FAR to promote LID construction. The System for Urban Stormwater Treatment and Analysis IntegratioN (SUSTAIN) model is applied to simulate the runoff reduction under various LID designs and then derive the Pareto-optimal solutions to achieve urban runoff reduction goals based on cost efficiency. The results indicates that the maximum surface runoff reduction is 20.5%. Under the extremity scenarios, the government has options to award FAR of 0.028, 0.038 and 0.047 and the net benefits developers gain are 0 CNY, one million CNY and two million CNY, respectively. The results provide a LID construction guideline related to awarding FAR, which supports incentive policy making for promoting LID practices in the highly urbanized areas.
