Study On Environment Impact Assessment Of The Provincial Land Remediation Planning

Cultivated land per capita little arable land, poor quality, reserve cultivated land relative shortage of resources, the obvious contradiction between human and land is the basic condition of our country. Land renovation is the main ways to alleviate this one contradiction. The current our country land renovation has entered a new stage of development, it is not only to ensure the national food security, and is an important way to promote the new rural construction and urban and rural development important platform and build land ecological security of the important measures. Seventeen third session put forward large-scale implement land renovation, do well the planning, overall arrangement, sectors-connecting propulsion, accelerate lower-yield fields, raise the quality of cultivated land and greatly increase proportion of high and stable yield farmland. Land renovation plan as land renovation activities of programmatic planning, is the overall planning of the land renovation activities and overall arrangement.In land renovation planning process of environmental impact assessment, can prevent and a slowing from the source of regional environment planning the adverse effects. At present our country carry out land renovation planning environmental impact assessment research to less, theory system, the evaluation index and evaluation methods are not perfect. Thus, in the new round of land renovation plan comprehensively launched circumstances, carry out land renovation planning environmental impact assessment is of important theoretical and practical significance.Based on the comprehensive analysis of the strategic environmental impact assessment both at home and abroad, land use planning environmental impact assessment and domestic land renovation planning environmental impact assessment based on relevant studies, through the analysis land renovation environment impact assessment for planning environmental impact factor, connotation, constructing evaluation index system, using quantitative research theory discussion with qualitative description, combined with the empirical research, using the method of hasn't province as an example, the regulation of environment impact assessment for planning land were studied. Preliminary made a conclusion that:1,Land renovation plan environment impact assessment is strategic environmental impact assessment, its purpose is to consider the environmental impact of the decision-making process into planning, in order to reduce or relief from the source adverse environmental impacts.2,Carry out land renovation planning environmental impact assessment, not only to the theoretical support includes land resources theory, it should also include economics theory and ecology theory, so this paper on the basis of previous studies, introduce a externality theory, environmental economics and environmental resources value theory. 3,Environmental impact recognition is based on environmental impact assessment on environmental impacts, is the necessary condition of the indicator system study. This article from the land renovation plan of the connotation of environmental impact assessment of ecological, social and economic from three aspects of land renovation plan to comprehensive evaluation of environmental impact. Selected the cultivated land per capita amount, land reclamation rate, basic farmland BaoHuLv, per capita net income of farmers improve rate, forest coverage, land desertification control rate, disaster prevention and mitigation capacity assessment index, thirteen.4,In land renovation plan environmental impact assessment methods, through the analysis of the relevant research achievements at home and abroad, this paper adopted often planning level chromatography and artificial neural network model method, using the same evaluation index respectively, the soil renovation planning environmental impact comprehensive evaluation.5,In the case of the analysis phase, through the analysis of the land renovation planning (2011-2020).The results of the AHP:the first scheme's ecological environment, social final environmental and economic environment are 15.33,32.45 and 21.70 higher than 2010 year, the environmental impact comprehensive is 21.20 higher than 2010 year;the second scheme's ecological environment, social final environmental and economic environment are 16.90,34.12 and 22.74 higher than 2010 year, the environmental impact comprehensive is 22.66 higher than 2010 year.The results carry out that land renovation planning integrated regional environment conducive to the improvement, and scheme ii degree than plan one improve the freshmen. BP neural network for the output of 4.11 plan one score, scheme, the corresponding 4.57 redquin respectively environmental impact level less impact on and minimal impact or no effect, demonstrated that the two land renovation plan in the environmental impact level are feasible, but scheme ii is superior to the plan one. It can be concluded that the integrated regional environment from effect to see, after the land renovation plan of regional environmental effects all have certain degree rise that carry out land renovation plan from environmental levels to say feasible. Meanwhile, judging from the analytical hierarchy process (ahp), take a scheme, environmental impact comprehensive scores are higher than the score, illustration, ecological environment in land renovation plan comprehensive environmental impact, the influence of ecological environment is the biggest. At the same time, this paper puts forward several targeted reduced or alleviate adverse environmental measures.
