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. Prof. Jianfeng Zhang works at the Institute of Subtropical Forestry, Chinese Academy of Forestry, Fuyang, China.

Abstract: China suffers from a host of environmental problems which have worsened over the past three decades of economic reform. Non-point source pollution in freshwater has become a striking issue around the country. The objectives of the research were to explore the knowledge and perceptions of the residents about non-point source pollution and community-based watershed management policies within Nansihu Lake watershed of China, their attitudes toward non-point source pollution control and watershed management, the amount of their willing to pay for water quality improvement, the differences among different groups of the residents regarding their knowledge, perceptions, attitudes towards non-point source pollution and watershed management policies, and their willingness to pay for improving water quality, and finally, the socio-economic factors affecting the residents' willingness to pay. The results indicated that the residents in Nansihu Lake watershed had low level of knowledge and perceptions of non-point source pollution, eutrophication, and community-based watershed management policies. Their attitudes toward non-point source pollution control were very positive. There was no direct cause and effect between respondents' knowledge and their attitude. With the combination of two major CVM formats, the survey results indicated that the urban respondents' median WTP was [CNY]157.5 (U.S. $19.69), while suburban and rural respondents' median WTPs were [CNY]100 (U.S. $12.5) and [CNY]50 (U.S. $6.25), respectively. The total amount of WTP per year in Nansihu Lake watershed was estimated to be [CNY]562.63 million (U.S. $70.33 million). The survey revealed that residents' yearly income and geographic locations were the main factors affecting residents' willingness to pay for non-point source pollution control in this area. Overall, there was no significant difference between urban and suburban residents in their knowledge, perceptions, and attitudes, but rural residents were significantly different from the two groups above. The research implied that 1) it is imperative for the local government to encourage residents to formulate community-based watershed management groups in Nansihu Lake watershed, China, 2) improving local economy and residents' income, increasing environmental education input, and enhancing residents' environmental awareness would be an effective approach for improving water quality in Nansihu Lake watershed.

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.

Agricultural operations can contribute to water quality deterioration through the release of several materials into water: sediments, pesticides, animal manures, fertilizers and other sources of inorganic and organic matter. This ''guidelines'' document on control and management of agricultural water pollution has the objectives of delineating the nature and consequences of agricultural impacts on water quality, and of providing a framework for practical measures to be undertaken by relevant professionals and decision-makers to control water pollution.
