| Since China’s reform and opening up, Chinese economy has gone through nearly30years of rapid growth, and in the process resources and environmental constraint effect on economic growth is also growing, protect the environment, change of economic growth pattern, from the high consumption, heavy pollution of high growth to low consumption, light pollution, realizing economic sustainable development, has become the top priority.South-to-north water transfer project as a strategic infrastructure project in China, is a major move of China’s sustainable development, its for the north-south distribution, can be something each other aid, reasonable allocation of water resources the formation of the pattern, from the overall improve the ecological carrying capacity in north China, it is of great strategic significance.South-to-north water transfer project because of its longest water diversion distance, the largest water under the party central committee and state council attaches great importance to.The middle route of main forest ecological environment construction, water quality security and protection but also relates to the success or failure of the south-north water diversion project.From a practical level, the middle route water catchment areas is not only a national strategy repository, especially during the "twelfth five-year" qinba area poverty alleviation crucial key battleground. Water ecological environment protection and regional sustainable economic and social development of the two major social responsibility is very heavy for the local government.This thesis is to explore the ecological environmental protection and the relationship between the sustainable development of regional economy and its impact mechanism, through the water source of south-to-north water transfer project shiyan as an example of quantitative analysis of a variety of possible influencing factors in the role of the relationship, and the ecological environment protection under the constraint condition of the regional economic sustainable development put forward policy recommendations and implementation approach.Paper first chapter compared comprehensively reviews the related literature at home and abroad, combing the theory of sustainable development, ecological economic theory, regional economic development theory and new economic growth theory research ideas and research methods, on this basis, try to theoretical analysis of ecological sensitive area economic sustainable development.Paper in the second chapter in-depth analysis of the characteristics of ecological sensitive area and the development goal, under the premise of building a framework for the sustainable development of ecological sensitive area, through the study of population, resources and environment for sustainable economic development restriction mechanism, deduced the endogenous growth model is environmental constraints, the best way to realize the sustainable development of regional economy.Paper third chapter detailed introduces the general situation of shiyan city, the water source of south-to-north water transfer project, and through the qualitative and quantitative analysis, confirmed the catchment areas of shiyan ecological sensitive area of this research is based.Thesis chapter4and chapter5in shiyan city, the water from1995to2011, statistical data as the foundation, on the basis of above analysis and research the mechanism of idea, first of all, through quantitative analysis of shiyan nearly15years the situation has carried on the overall evaluation of sustainable development, and then through the analysis evaluation of the regional population, resources, environment and economic development coordination and coordinated development level between four system, environment system is obtained not only directly affect the economic growth and economic development, and through the impact on the rest of the system of indirect shiyan economy.Under the condition of the reality of development constraints, the endogenous growth model has become the only way to break the shackles, the paper through the analysis of shiyan main power comes from the nearly15years GDP growth and its human capital investment, fixed assets investment, consumption, and technological progress, the human capital investment increased by1%, the current GDP will rise by0.741%; Technological progress index increased by1%, the current GDP increased by0.96%.Through theoretical and empirical studies show that the region’s current development path is the right, but for the increasingly enhancement of the ecological environment pressure and rich responsibility, it is not enough, the future still need more efforts to promote the development of ecological economy, increase investment in human capital, promote technological progress, drive the adjustment of industrial structure, thus effectively reducing environmental constraints, and achieve the goal of sustainable economic development.According to this conclusion, the thesis in the sixth chapter put forward for the ecological sensitive area economic sustainable development of shiyan city, the water main path, i.e., according to the development of green GDP as the goal, intensifying ecological construction, grasping the ecological development of the economy.Ecological construction in order to protect the ecological environment of water source and water quality safety as our highest priority. Ecological economy powered by technology progress, transformation of the mode of development, to develop efficient ecological agriculture and environmental friendly industries, and actively develop the local tourism and cultural industry, build a complete system of ecological industry.The innovation of the thesis mainly have three points. The first point is focused on ecological construction under the background of large-scale engineering water economic sustainable development, ecological sensitive area economy sustainable development, expand the regional economic sustainable development research. The second point is system research the influence of the factors that influence the sustainable development of ecological sensitive area economy mechanism. Economic sustainable development of ecological sensitive area must be population, resources, environment and coordinated development of economic system. The third point is to quantitative the various factors effecting the shiyan economic development main forest targeted put forward the economic system and the framework of sustainable development of shiyan city, the water concrete path. |
