Study On Environmental Impact Assessment Of Nanli Lake Scenic Area Land Use Based On Evaluation Of The Coordination

Land is the basis of ecosystems, rational planning and use of land resources related to the balance and stability of ecosystems. With the development of tourism, the contradictions between land use and the environment has become increasingly prominent in tourist attractions. Environmental impact assessment of land use can effectively avoid the adverse effects of improper land use patterns on the ecological environment, and improve the ecological and socio-economic efficiency to achieve sustainable development of regional tourism and the environment.This thesis takes NanLi Lake Scenic Area as the researched object, according to ecology, sustainable development, system science theory, combined with scenic environmental conditions and the actual situation of socio-economic development, through 3S technology, field research, data analysis and other scientific methods to obtain metrics data.And then, construct evaluation index system of ecological environment and land use,forecasting and research around the implementation of land use planning, land use changes,ecological state structure, environmental stress, environmental governance, land use degree,land use efficiency level,economic development and population. On these basis, through the coordination of the model,research coordination and development between the land-use and environment.Finally, according to the findings made recommendations corresponding measures to achieve a balanced between land use and environmental protection work of NanLi Lake,provide a reference for the resort industry and ecological environment for sustainable development.Through the theoretical exploration and practice research got the following results:1. This paper built an environmental impact assessment system of land use for tourism scenic area from the perspective of coordination. And study the response relationship between the ecological environment and land use system.2. The paper Analyzed Hainan NanLi Lake land use change and its ecological coordination. Land use of study area will bring significant impact on the ecological and social economic environment: after the plan implementation, land utilization change significantly in the study area, the mutual transformation between various land use type.Land use planning has negative effects on the ecological environment. But the economic benefit of land will be significantly improved, people in the scenic will benefit from the development and construction of scenic spots.3.The ecological coordination degree level of land use increased to good coordination from near disorders, the coordinated development degree change into a higher level.Paper based on coordination analysis, using the land ecological function changes as a bridge to identify impact, building an environmental impact assessment system of land use for tourism scenic area. paper for the land use planning environmental impact assessment provides a new thought and method. What's more, it can provide a reference basis for the scenic area planning and construction. Paper has certain innovation and practical value on the theory and method of environmental impact assessment.
