Lake Taihu China

2 In China, there are more than 2,759 lakes with surface area greater than 1km , and 2 the total lake area is 91,019km . One-third of these lakes are freshwater lakes, and the majority are situated in the middle and lower reaches of the Changjiang River or in eastern China’s coastal areas. These lakes function as drinking water supplies, ood control systems, aquaculture and tourism resources, navigation channels, etc. Recently, many shallow lakes in China have been subject to rapid eutrophication and suffer from algal blooms. This issue has resulted in a shortage of drinking water and in degradation of their ecosystems. The control of eutrophication of shallow lakes is one of the main issues with which the local people and Chinese governments are concerned today. Lake Taihu is the third largest freshwater lake in China, with an area of about 2 2338km and a mean depth of 1. 9m, a typical shallow lake located in the delta of Changjiang River, the most industrialized and urbanized area in China. Its main function is supplying drinking water for the surrounding cities, such as Wuxi, Suzhou, and Shanghai, but tourism, aquaculture, sheries, and navigation are imp- tant as well. However, with economic development and increased population in the lake basin, Lake Taihu has suffered increasingly from serious eutrophication. The environmental issue of Lake Taihu is now a very common one, as most lakes from eastern China are confronted with it.

This volume features papers presented at the International Symposium on the Eutrophication Process and Control in Large Shallow Lakes-–with Special Reference to Lake Taihu, held in Nanjing, China in April 2005. Coverage includes: physical processes and their effects on shallow lake ecosystems; biogeochemistry of sediments and nutrient cycling in shallow lakes; and algal blooms and ecosystem response in shallow lakes.

"Dark, gorgeous...feels authentically Chinese and it works like a charm." --Washington Post Book World on A Case of Two Cities Chief Inspector Chen Cao of the Shanghai Police Department is offered a bit of luxury by friends and supporters within the Party – a week's vacation at a luxurious resort near Lake Tai, a week where he can relax, and recover, undisturbed by outside demands or disruptions. Unfortunately, the once beautiful Lake Tai, renowned for its clear waters, is now covered by fetid algae, its waters polluted by toxic runoff from local manufacturing plants. Then the director of one of the manufacturing plants responsible for the pollution is murdered and the leader of the local ecological group is the primary suspect of the local police. Now Inspector Chen must tread carefully if he is to uncover the truth behind the brutal murder and find a measure of justice for both the victim and the accused.

Based on the past 30-years' research on the technical and cultural values of China's Grand Canal, this book, based on interdisciplinary research, studies the natural and social background of the evolution and development of different sections of the Grand Canal in different historical periods, as well as the interrelations between the Grand Canal and the Chinese politics, economics, and culture. It also assesses the effects of the Grand Canal on the progress of the Chinese civilization, engineering technology achievement, the natural environment, and the society, providing the readers with an understanding of China's Grand Canal from the perspectives of hydraulic engineering and history.

This report presents both short- and long-term approaches to the problem of marine plastic debris and micro plastics. It provides an overview of the latest science and experiences, identifies priority areas of action, and points out areas requiring more research. Improved waste management is urgently needed to reduce the flow of plastic into our oceans.

This book mainly focuses on ecological approaches for preventing and controlling non-point source (NPS) pollution on the basis of forestry measures. In addition to the effects of ecological control, it introduces readers to the characteristics of NPS pollution in Taihu Lake watershed, water eutrophication evaluation methods, and potential countermeasures. Given the crucial role of surface runoff and soil erosion in producing water pollution, the book presents forestry measures to combat them, such as the creation of public welfare forests, urban forestry, planting techniques for hedgerows on slope land, the establishment of shelter belts, nitrogen and phosphorus absorption by hydrophytes, and sustainable management for wetlands. Moreover, the results are supplemented by a wealth of numerical calculations, tables, figures and photographs. The book offers a valuable guide for researchers, educators and professionals working in the areas of water environment, water security and ecological construction.
