| As a must for human being's survival and development, the quality and quantity of water are both affected by nature and human being's activities, but also influence them on the contrary. Water in a basin is always moving circularly. The circular moving of water is characteristic of basin, while a basin has not a same borderline as a district. In China, the management system of water resource and water environment, as a rule, are not compartmentalized by basin but by district, which is no more adapt to water resource management. In a basin, water environment management has become one of most important domains of the sustainable development of society, economy and environmentBased on the material collection, on-the-spot investigation, experts' consolation, data statistics and analysis, the following study is finished. In this paper consists of six chapters: an exordium of the paper, a survey water environment management at home and abroad, the water environment management in Xin'an River basin, the coupling of water environment management and tourism development, a route of tourism development of Xin'an River, and a summary of the study.First, this paper expounds the aim and meaning of the study in the exordium, and then the content and method in Chapters Two.Then, taking Xin'an River basin in Huangshan City as a case of study, exerting GIS technique, combining theories and practices of water environment management, referring the national Environmental Quality Standards for Surface Water and basing the status of Xin'an River basin in Huangshan City and the inspection data of surface water in Xin'an River basin (1998-2002), this thesis adopts here Nemerow exponent formulas of water quality to estimate and analyze the water quality of Xin'an River. And it puts forward the countermeasures of water environment management as to combine water environment management in a basin and that in a district, to compartmentalize water functions, to father water pollution and soil erosion, to adopt GIS technique, and to set up an environment compensate system in Xin'an River basin.Finally, this thesis also analyses the coupling relationship of water environment management and tourism development in a basin from the relationships of mutual dependence and mutual restrict. And on basis of which it discusses the tourism development measures of Xin'an River as to stick to the principle of tourism sustainable development, to adhere to combining tourism development and water environment management, to frame a tour programming, exploit tour products and establish a name-brand tour destination, to enhance tour cooperation and united operation in the basin, and to join in "Yangtze River Delta" to fulfill the great tourism development of Xin'an River. |
