Ecological Environment Impact Assessment Of Land Consolidation

Our current contradiction between people is still very tense, especially arable land,18 million mu of arable land to adhere to the red line is an urgent need to address the problem. Through land consolidation, can effectively increase the arable land, and thus protect the country’s food security. But in the land consolidation activities inevitably impact on the local ecology. Then study the ecological impact assessment of land consolidation environment, it is very necessary and meaningful. Ecosystem Environmental Impact Assessment of Land Consolidation can guide the smooth implementation of land consolidation project planning and design, and the local ecological environment.In the actual process of ecological environment impact assessment and evaluation methods are more complicated and difficult to carry out, so the impact assessment study of simple and feasible method of ecological environment is very important and meaningful.This article is based on land consolidation project of Xiantao City West Town seven villages, by studying the ecological environment impact assessment procedures, index system, evaluation methods, calculation methods, examples of specific binding studies, the main draw the following conclusions.(1) Research ecological environment evaluation of technical specifications (Trial) (HJ/T192-2006) the method for calculating the normalization factor. When carrying out land consolidation activities, the ecological environment in the affected area to be evaluated, it may be across different regions, each region due to ecological differences, so during the ecological impact assessment of the administrative villages paper here into the intermediate value is calculated in units of a, then select the maximum intermediate value A, calculating a normalized coefficient index. This normalization coefficient calculation can be found in the village-level units of land consolidation project to promote.(2) According to the ecological environment evaluation of technical specifications (Trial) (HJ/T192-2006) of the index system, the index weight and calculation methods, land reclamation index used here instead of the land degradation index, before and after land consolidation project area were the ecological environment impact assessment, the conclusion is that the land consolidation project is feasible, the local ecological environment has had a positive impact. This is a quantitative analysis method is simple, easy to implement.(3) Try the feasibility of the ecological footprint, the ecological impact of Xiantao City West Town of land consolidation project, quantitative evaluation by calculating the ecological carrying capacity of the land consolidation project implementation before and after comparison, the change was not significant. Ecological footprint method is just a static analysis method can only reflect the status of the region’s ecological environment; ecological footprint ecological carrying capacity method by which a single evaluation index to reflect the impact assessment of the region’s ecosystem, the result is relatively simple, does not have a strong convince force.
