Study On The Environmental Impact Assessment Of The Overall Land Use Planning

Land use is a process, which is to land according to its mass property. By creating the wealth and improving the environment, it can meet the need of production, life and human survival. Land use planning, as a planning form to guide land use, not only restricts the current social economy development, to the forward ecological environment impact also is not allowed to neglect, closes the sustainable development strategic target.The overall land use planning, which has comprehensive impact, occupies the highest strategic level. By bringing the environmental impact assessment into line with the ecological environment to in the planning formulation process, establish policy-making mechanism, the overall land use planning establishes a kind of environment, the economy and the society synthesizes.At present the domestic land use planning environmental impact assessment is at the start stage. The related impact appraisal theory, the method, the system and so on urgently wait to be established. This article based on the system research on environmental impact assessment rationale, summarized the characteristics of land use planning environmental impact assessment, tried to establish an environmental impact assessment system according to the specialty of the land use planning ,namely through the analysis of impact that all kinds of activities possibly produces to the environment, studies on the environmental effect recognition, thus establish environmental impact assessment system, the most important part of appraisal target system, chooses land use planning environmental effect synthesis appraisal method, estimate different land use, provides the reference for plan screening. And has conducted the example research take Siping as the example.The above research obtains the following conclusion:(1) The land use planning environmental impact assessment from environmental angle weight the sustainability of land use planning , appraise the environmental effect brought by using land systematically, scientifically appraises, and proposed conforms to the sustainable development requirement to slow down, the remedial treatment or the alternative scheme, provides the environment basis for the final planning decision-making and the implementation; But the land use planning execution environment response is the environment in turn urges the land use planning smooth implementation or recarries on the power which the planning cannot neglect. This mutually affects mechanism evidence land use planning environmental impact assessment research importance.(2) The overall land use planning level, the instruction, the integrity, characteristic and so on the policy, had made the overall land use planning environmental impact assessment has the comprehensive nature, not the determinism, strategic, the subordinate and the instruction characteristic and so on the level.(3) The land use planning environmental impact assessment system is established on the land use planning analysis, plans the regional land use and in the social economy present situation analysis foundation, including the environmental effect recognition, the environmental impact assessment target system establishment, the alternative planning and so on synthesis appraisal complete system.(4) Land use planning environmental impact assessment system index system has three levels: General target tier, environment subject target tier, index tier. Among them , general target is land use master planning scheme environmental impact assessment system tier; The environment subject target is to distinguish the environment subject that result finds out from big targets affecting correlativity to the environment according to the environmental effect tier, is four big including resource , environment , society , economy arrangement of ideas; The index is tier of many indices tier reflect environment target concretely, include index such as forest coverage rates , per-capita amount of farmland , loss of soil and water area.(5) Taking Siping City as a case for demonstration study, this paper adopt arrangement of ideas analysis law when weight ascertains the weighted comparison method having chosen as the environmental impact assessment system method , in the index. Indicate to the scheme valuation result: The lurking problem that scheme A reports is that the government will enlarge the fixed investments number, the agriculture carrying out mistake builds large amount of occupancy cultivated land, Economy increases per capita GDP over greater than though the base period year degree having bigger rise, but environmental pollution exponent rise comparatively degree, have an adverse effect therefore, to the general target realizing the long range sustainable development ecological environment. The government has enlarged improvement of the ecological environment , has readjusted oneself to a certain extent with the focus of work having arrived at ecological conservation aspect during that period when scheme C lurking problem is to be put into effect in the plan, land use ratio is still lower but , has not made use of a field to develop degree still very low, but by cutting down cultivated land , being to be a wasted effort to come to be engaged in ecological conservation water area, Owe a scheme and economic growth slowly , have no way to satisfy the material culture need that people improves unceasingly , satisfy the development strategy that our country economy the coming 10 increases rapidly neither. Scheme B is a fairly good plan which harmonizes the relations among society, economy, and environment.
