《环境科学与工程前沿(英文)》 2010年 第4卷 第2期   页码 213-220 doi: 10.1007/s11783-010-0023-6

摘要: An index system for evaluation of technologies for urban river rehabilitation was proposed and discussed. The index system includes indicators of cost, resources, environmental improvement, and social effects. The calculation method for an objective value of each index based on its attributes and weights was presented. The Foshan Channel, which is a seriously polluted, black and malodorous urban river in Foshan City, China, was selected as a case study. The values of the attributes and the weights of the indices for the Foshan Channel were determined. The technologies for the rehabilitation of the Foshan Channel were evaluated based on this index system. Finally, a rehabilitation scheme for the Foshan Channel was proposed.

Ecosystem health assessment of urban rivers and lakes

ZHANG Fengling, LIU Jingling, YANG Zhifeng, LI Yongli

《环境科学与工程前沿(英文)》 2008年 第2卷 第2期   页码 209-217 doi: 10.1007/s11783-008-0007-y

摘要: The assessment of the ecosystem health of urban rivers and lakes is the scientific basis for their management and ecological restoration. This study developed a three-level indicator system for its assessment. The results indicated that: Zhonghai and Nanhai are in the state of transition from unhealthy to critical state and all the other lakes are in unhealthy states. Water environmental quality, structure and function of the aquatic ecosystem, and the structure of waterfront areas were the constraints. Nanhai was ranked as poor and the others were all ranked as very poor. However, the ecological environment of Zhonghai and Nanhai were better than the others, the sums of the degree of membership to the healthy state and critical state were all close to 0.6. and the restorations of these lakes were moderate. The sums of the degree of membership to the healthy state and critical state of the other lakes were under 0.3, as it was difficult to restore these lakes. Some suggestions on scientific management and ecological restoration of the six lakes were proposed: $`To control non-point pollution and to improve the water quality of six lakes and the water entering into these lakes; $aTo improve the hydrological conditions of six lakes; $bTo rehabilitate the aquatic ecosystem and waterfront areas.

摘要:

城市河流生态流量不足的现象普遍存在。除各用水部门之间竞争加剧以及生态流量保障措施执行不彻底等已知原因外,堰高设计中未明确考虑生态流量,是导致生态流量无法满足的另一个重要原因。本研究建议将生态流量的保障措施从供水阶段扩展到河道的设计阶段。为了更有效地满足城市河流的生态流量,本文构建了一个新的堰高确定框架。有别于传统框架中堰高设计重点关注防洪和蓄水要求,并以洪水入流作为设计依据,新的框架中增加了对生态流量以及河流流速维持的考虑,将城市河流中能为生态流量保障提供的实际流量作为入流。本研究以典型的城市渠化河流——合肥市十五里河为案例,对新框架的有效性进行实证研究。研究结果表明,旧框架会导致设计的堰高过高,无法有效满足生态流量保障的要求,而新框架可确定更为合理的堰高,从而改善了生态流量的保障效果。

城市渠化河流生态流量核算方法 Article

尹心安, 杨志峰, 张恩泽, 徐志豪, 蔡宴朋, 杨薇

《工程(英文)》 2018年 第4卷 第5期   页码 590-596 doi: 10.1016/j.eng.2018.08.006

摘要:

城市河流生态流量核算对于水资源规划和河流保护非常重要。以往城市河流生态流量核算方法侧重于满足物种生境维持和污染物稀释的需求。然而,城市河流中很少存在需保护的物种,同时大量城市河流为混凝土化渠道,无需考虑物种生境维持需求;另外,随着城市水污染防治工程的建设,一些城市河流的污染问题可得到有效的控制。对于这类城市渠化河流,如果沿用以往的生态流量核算方法,即从物种生境和污染物稀释的角度来确定生态流量,生态流量的核算结果将很小,潜在地降低了未来水资源分配和管理中对河流生态保护的重视程度。为了更有效地核算渠化城市河流的生态流量,除了满足污染物稀释的需求外,本研究依据河流纵向水文连通程度的不同(高、中、低),提出了3 种情景下的生态流量核算方法。在高水文连通情景下,生态流量旨在维持一定的水流流速,以确保河流的自净能力并减缓藻类的繁殖;在中水文连通情景下,生态流量旨在维持城市河流中被拦水堰分割河段之间的纵向水力连通性,以确保河流中的物质、能量和信息间的交换;在低水文连通情景下,设计的生态流量将进一步减小,改为间歇地向城市河流补水,旨在满足被拦水堰分割河段间的间歇性连通。本研究以十五里河为研究案对象,研究结果表明新建立的生态流量核算方法可以提供更加精确、符合实际的生态流量核算结果,并为生态补水工程的建设和管理提供有效的指导。

摘要: The occurrence and removal of 13 antibiotics were investigated in five wastewater treatment plants (WWTPs) with advanced wastewater treatment processes in Beijing, China. Most of the target antibiotics were detected in the secondary and tertiary effluents, with the concentrations of 4.8–1106.0 and 0.3–505.0 ng·L . Fluoroquinolone antibiotics showed relatively high concentrations in all samples (782–1814 ng·L ). Different tertiary treatment processes showed discrepant antibiotics removal performances. Ozonation process was found more effective in removing target antibiotics compared to the coagulation-flocculation-sedimentation process and sand filtration process. Investigation of the target antibiotics in three typical urban rivers in Beijing was carried out to understand antibiotics occurrence in surface water environment. Eight antibiotics were detected in the studied rivers, with highest concentration of antibiotics in the river which was mainly replenished by reclaimed water. This study showed the necessity of employing more effective advanced treatment facilities to further reduce the discharge amount of antibiotics.

摘要: China’s mega urban regions are focal points of economic development and environmental concerns. This paper positions four mega urban regions (i.e., the Yangtze River Delta, the Pearl River Delta, the Bohai Bay Area, and the South-eastern Fujian Province) along China’s coast into the national economy and elaborates their development challenges and planning innovations. Mega urban regions in China are spatial consequences of rapid economic transition. They deserve close scrutiny and demands for innovative planning responses in order to maintain their key role in driving economic growth but limiting their greenhouse gas emission.

摘要: Pollution from diffuse sources (pollution from contaminants picked up and carried into surface waters by stormwater runoff) has been identified as a significant source of water quality problems in the U.S. scientists and engineers continue to seek solutions that will allow them to optimize existing technologies and develop new ones that will provide the best possible protection to people, wildlife, and the environment. This paper addresses the various pollutants or stressors in urban stormwater, including flow (shear force), pathogens, suspended solids/sediment, toxicants (organic and metals), nutrients, oxygen demanding substances, and coarse solids. A broad overview of the pollutants removed and the removal mechanisms by and of conventional best management practices (BMPs) is also presented. The principal treatment mechanisms of conventional wet ponds, vegetative swales/buffer strips, and wetlands are sedimentation and filtration. These mechanisms have the capability to remove significant amounts of suspended solids or particulate matter and are a vital component of strategies to reduce pollutant loads to receiving waters. In addition, because most of the nation’s receiving water violations are caused by pathogen indicator bacteria, it is of utmost importance that research efforts address this problem. Further research is also needed on the treatment of emerging contaminants in BMPs and on the costs and affects of maintenance and maintenance schedules on the long-term performance of BMPs.

摘要: Few studies have been conducted to assess the level of physical activity (PA) of women in China. The purpose of this study was to describe the prevalence of PA among women in Wuhan and explore sociodemographic and behavioral correlation to PA for the population. A total of 1359 community-dwelling women (42.9713.60 years old) participated in this study. The long-version IPAQ was used to define the level of PA. 45.7% of women were considered physically active, and 27.5% were vigorously active. The proportion of physical inactivity was around 26.8%. The total and 4 domains of PA showed significant age, education level, and occupation variation. PA tended to be lower as the age declined. PA in transportation, housework, leisure time, and the total tended to be the lowest or the second lowest among the women aged 18–35 years old. PA tended to be lower as the level of education increased. Among the 5 indices, PAwas the lowest among women with college education, especially those with postgraduate education. PA tended to be the lowest among the women of office staff and instructor or technician. Generally, the total and 4 domains of PA showed significant age, education level, and occupation variation. Physical inactivity appears to be more common among younger women, or college-educated women, office ladies, and female instructor and technicians.

Coupling analysis of passenger and train flows for a large-scale urban rail transit system

《工程管理前沿(英文)》 2023年 第10卷 第2期   页码 250-261 doi: 10.1007/s42524-021-0180-2

摘要: Coupling analysis of passenger and train flows is an important approach in evaluating and optimizing the operation efficiency of large-scale urban rail transit (URT) systems. This study proposes a passenger–train interaction simulation approach to determine the coupling relationship between passenger and train flows. On the bases of time-varying origin–destination demand, train timetable, and network topology, the proposed approach can restore passenger behaviors in URT systems. Upstream priority, queuing process with first-in-first-serve principle, and capacity constraints are considered in the proposed simulation mechanism. This approach can also obtain each passenger’s complete travel chain, which can be used to analyze (including but not limited to) various indicators discussed in this research to effectively support train schedule optimization and capacity evaluation for urban rail managers. Lastly, the proposed model and its potential application are demonstrated via numerical experiments using real-world data from the Beijing URT system (i.e., rail network with the world’s highest passenger ridership).
