Study Of Land Use Change And Ecological Service Value Change In The Experimental Region Of New Rural Village Construction

Facing the problem of population-resource-environment, the whole world change especially land utilization/ land covers change is becoming one of the most enlivening studying fields in recent years. With the intersecting and mixing in subjects, the quantitative estimate of ecosystem economic effect is managed and the research fruits also begins to be applied and be one of the important factors which appraise the land use is reasonableness or not. In 2005 the Central Committee of the Party and State Council brought forward the historic task "building the new rural area of socialism". The land use and relevance studies in the experimental area of new rural construction have already become a new representative area case in the land use study of our country. The paper takes the analysis of land use degree and structure change as the main body, reveals the driving forces of land use change, and analyses the impacts of land use change over the change of ecological service value backward. Setting up the baishiyi town and gaofengsi village the experiment of national grade as examples, the paper analyses qualitatively and quantitatively to find the characteristics of the land use change in the experimental regions of new rural village.First of all, the paper prefaces the whole. It expounds the background, significance, content, method and train of thought of the research and summarizes the fruits of relevance research. Secondly it introduces the general situation of geographical feature and society economic growth in study areas and shows the source of data. Then is the key, including the analysis of land use change characteristics, driving forces, the impacts of the change of the ecological service value. In the research of land use degree change, discussing the method of the comprehensive analysis of level Four classification, and being aimed at the reality's conditions of new rural village experimental regions it proposes a new microcosmic model and quantitatively analyses the changes of land use degree over 10 years take the Baishiyi town as the example to reveal the characteristics. In the research of land use construction change, it compares the differences between the experimental Village and the average of its district taking Gaofengsi village as example and then revels the peculiar rules of the change of land use structure, the direction of land use transformation and the rate of change in the experimental village of new rural village construction. In the research of driving forces of land use change, using principal components analytic method finds its main forces are population structure factor, industrial composes factor and agriculture technology factor. And researching the driving forces of the policy of new rural village construction with the Partial Least-Squares Regression, concludes that the main factors are agricultural structural adjustment, land operation way converting, infrastructure construction in rural area and the building of peasant's new residence. In the research of impacts of land use change over the change of ecological service value, ascertains the service value in unit area and estimates the change and analyses the characteristics, then indicates that the land use change is beneficial to ecological environment and the whole value is increasing. Finally the paper makes the conclusion of main points and presents proposals in regional land use. And it also points out the shortage of itself and brings forward the further future of the study.
