In view of the situation of the Yangtze river waterfront resource development and existing problems in Anhui in recent years, through the investigation and research of the waterfront, accumulating and discerning the forms of utilizing waterfront, and then based on Yangtze river waterfront development condition in Anhui,development status and development needs, and the functions of ecology, life and...
Soil and water loss is an important source of water eutrophication. In this study, soil erosion were measured in the four types of cultivated lands (Paddy land, Terraced farmland, Sloping farmlands <; 25°, and Sloping farmlands ≥ 25°) in Xiaojiang River basin, Chongqing of China. In addition, water qualities were investigated in 5 reaches of Xiaojiang River (Qukou, Yanglu, Gaoyang, Huangshi, and...
The variation characteristics of runoff and sediment transport in main hydrologic stations of the Dongting lake was analyzed by methods of mathematical statistics, Mann-Kendall, wavelet analysis and accumulating filter from 1956 to 2008. The results show that: (1) the water and sediment entering Dongting Lake are mainly from four rivers of Hunan and the three outlets of Jinjiang River, respectively,...
This paper discusses the water environment vicissitude in the middle reaches of Yangtze River from four stages in history. Taking several typical cities Jingzhou, Wuhan, Yichang as examples, the author analyzes the impacts of water environment vicissitude on urban spatial position, structure, function, rise, fall and distribution in the middle reaches of Yangtze River.
This paper supposed a fast-estimation method about soil erosion intensity based on multi-source spatial information integration, taking an example of Yangxin County in the middle reach of Yangtze River. At first, under geographical background of research region impact factors are put forward; then, using remote sensing data and vegetation index model extracts the land use types information and vegetation...
Poyang Lake is China's largest freshwater lake. It has good regulation role to Yangtze River. After the running of Three Georges Project, it influences the water level of Poyang Lake a lot. This paper predicts Poyang Lake's water level, it is the basic of influence research. Once there were many predicting methods, such as ANN, etc. But these methods are not very precisely. This paper uses wavelet...
