Study On Sustainable Utilization Of Land Resources In Three Gorges Reservoir Area

Three Gorges Project is the world’s largest water conservancy project, after the construction of both flood control, power generation and navigation and other functions, but also the formation of the world’s wonders-the Three Gorges Reservoir. Three Gorges Project has a positive and negative impact on the ecological environment. Forward is to solve the Yangtze River floods, power generation capacity to save a lot of coal use, conserve resources while reducing pollution from coal combustion. The negative effects of a major impact, first of all, changing the topography of the environment of the Three Gorges region, hundreds of villages and towns were flooded. Construction project has the potential incidence of induced earthquakes occur, landslides, mudslides and other natural disasters, far more than in the past, soil erosion has been a major obstacle to the region’s ecological security. Land use patterns is the basis for all activities of the people, is the foundation of the entire ecosystem and socio-economic systems. Therefore, in order for sustainable development in the Three Gorges reservoir area, we must study the Three Gorges Reservoir land use meets the concept of sustainable development, the paper Fengdu County, for example, carry out research on this issue.Fengdu County is part of the Three Gorges reservoir area, due to the scope of the Three Gorges reservoir area is relatively large, the level of difficulty of their direct study of sustainable land use is relatively large, and therefore, this paper Fengdu County, for example, through the county’s land use to reflect the overall situation of the Three Gorges Reservoir Area. And based on the results of the analysis of Fengdu County land use sustainable level at this stage to judge, has been based on the development trend of decades of land use to speculate about the future direction of development of land-use efficiency Fengdu County.Based on the specificity and ecological conditions in the Three Gorges reservoir area, select the 25 indicators established Fengdu sustainable land use evaluation index system, comprehensive analysis hierarchy process, entropy Combination approach to index weight assignment, and finally use multi-objective linear programming model for sustainable land use Fengdu County conducted a comprehensive assessment to determine the current land Fengdu county level and trend of sustainable use before 1 year. And to evaluate the results based policy recommendations. Studies have shown that between 2003 an 2012 Fengdu sustainable land use levels are rising. Fengdu County land use sustainable level is not high, but the evaluation score rose from 0.18 in 2003 to 0.42 in 2005, the overall trend showed a steady rise.1,2003 Fengdu County land use also in a non-equilibrium state. A low level of productivity, land resource use more extensive degree of economic and social development is very low, the ecological environment is also facing tremendous pressure. Affect the construction of the Three Gorges Project has become increasingly apparent. 10 years, due to the development of the productive forces of various government policies, and economic and social leap of Fengdu County development, land resources development intensity increases, utilization increases. On the other hand, although the government continues to strengthen control of soil erosion and other geological disasters, with remarkable results, but only eased the pressure on environmental pollution, deterioration of the ecological environment and provide a fundamental solution. Therefore, in 2012, the degree of development of an integrated system can be drawn each Fengdu weak sustainability.2, Sustainable land use coordination degree analysis. The research period Fengdu county sustainable land use coordination degree in the basic state of coordination, but the level is not high, but has declined in recent years. This is the protection of Fengdu County itself is difficult geological disasters, resources and excessive pursuit of economic interests of the results.3, the economic factors on the sustainable use of land restricted role in weakening, the problem of soil erosion, land protection is still the factors of sustainable land use disorder. The development trend of the economic and social consensus. But Fengdu County in the Three Gorges Reservoir area, charged with the protection of the Three Gorges ecological environment responsibility, so to do more environmental protection. In order to meet the connotation of sustainable development, in the not too optimistic about the evaluation results, this paper puts forward some suggestions and Countermeasures to these problems. The first is to change the concept, the pursuit of economic development is the outdated thoughts be inopportune or inappropriate in this model of development, but also to the human bitter lesson. Therefore to abandon this idea, to protect the ecological environment in the first place. Intensive use of land resources, improving agricultural practices, natural disasters, scientific management of cultivated land protection measures is to improve the effective method of sustainable utilization of land.4, in addition to the improvement of the practical significance of land use in Three Gorges Reservoir area, but also has a certain theoretical significance. Land sustainable use is relatively simple and feasible evaluation scale, based on the characteristics of the Three Gorges Reservoir area, suit one’s measures to local conditions to establish an index system, which has a certain reference significance of this empirical research on Sustainable Utilization of land in china.
