| The Human living space has experienced the ancient and medieval settlements inhabited by ecological, ecological spontaneous loss, in modern and contemporary modern ecological consciousness awakening in four stages(Huang Guangyu, 2002). The different modes of the economic and social development needs of different social and environmental ethics as a support, so as to form a pattern and thinking of the corresponding social mainstream value system(Yu Mouchang, 1994). Especially in our modern urban settlement space in the process of practice, in the human "the human center principle", "economy oriented" ideas or objectives under the guidance of, large-scale urban expansion resulting in the original surface system, great changes have taken place, the original ecological natural pattern and habitat ring exit system was severely damaged, man and nature face major challenges. A living environment of the city as the transformation of human nature is the most thorough, people in different historical stages, and transform the natural values and the true expression of the will. And the use of human on the natural environment and transform directly for human use of the land, different level and style will also have different effects on natural systems, and then attached to the land ecological environment system and water resources system have the influence. Therefore, land use for the development of water environment effects of, for understanding the relationship between land use and water environment, process and the causes of plays an important role, to fundamentally understand, has extremely important significance to solve the basin water environmental problems.The Chongqing Liangjiang New Area as an example, by using the method of association studies, system research, mathematical models of, in Liangjiang New Area, the current land use and water environment problem, namely the three big problems of water security, water ecology, water, landscape oriented, focuses on the study of Liangjiang New Area, the land the interaction mechanism between the water environment and, in order to provide integrated water environment management of small watershed in Liangjiang New Area land use strategy, different scenario planning research and planning of the situational simulation was put forward based on water environment results.Text is divided into the following seven chapters:The first chapter: the introduction part, account of global climate and flood disasters increased background, the current land use problems and crisis of water environment; through the domestic and foreign research review, achievements and shortcomings of the current research focuses on the analysis of land use and water environment; put forward Liangjiang New Area land use ecological strategies are important significance are discussed from the water environment management and land use of relevance.The second chapter: Liangjiang New Area of research and sort out the problem, contains three levels: Liangjiang New Area land use and water environment investigation; Liangjiang New Area of the current planning management method research; Liangjiang New Area current planning research.Chapter three: to analyze and summarize the Liangjiang New Area of land use on water environment evolution of the driving mechanism, mainly from three aspects of study: construction land on water environment impact; non construction land on water environment impact; water space structure using the impact on water environment.Chapter four: to analyze and summarize the Liangjiang New Area Water Environment on land use constraint mechanism, in the partition of water environment constraints of natural conditions of water environment on the land use function, the influence of water space structure of land use pattern, water environment management of land using three levels of policy implications.Chapter five: in Liangjiang New Area water environment target oriented, the Liangjiang New Area ecological strategies, control the scale of land, land type guide, land form cloth and water environment strategy planning and management of--Construction of drainage pattern, control of water environment, rain and sewage control land use under the constraint regionalization of water environment.Chapter six: the ecological strategies of research and put forward construct the ecological planning of four different scenarios, and carried on the simulation of water environmental quality, and thus the formation of the comprehensive goal of Liangjiang New Area land use ecological planning concept.The seventh chapter summarizes the research results and puts forward the prospect of future land use planning, but also to analyze the research innovation and shortage. |
