On Land Layout Of Ecological Shelter Zone In General Land Use Planning

The study on land arrangement for ecological shelter zone is an emerging subject in general land use planning. Land for regional ecological shelter zone is an important guarantee for preserving regional ecological balance and improving ecological condition as well as for the improvement of comprehensive and sustainable development. General land use plan should be compiled according to the land pattern of ecological shelter zone in full consideration of the integrality and stability of ecological function to avoid any functional change. In order to coordinate the relationship between the development of national economy and the preservation of ecological environment and bring both up to a more scientific and rational level through the regulation of mode, scale and structure of economic development together with an effort to restore the balance among sub- ecosystems, it is necessary to identify the layout of ecological shelter zone to provide guidance for proper development of natural resources and reasonable industrial distribution on the basis of through understanding of the regional ecological conditions.With a summary on the former research on land for ecological shelter zone and a review of the research progress, this thesis first discusses the definition and connotation of land for ecological shelter zone and puts forward relevant theories applied in the research. Four methods are then adopted in this thesis to carry out the study on layout of ecological shelter zone, namely the heterogeneity analysis, analysis of land patch including analysis of patch characteristics and patch gap analysis, evaluation of ecosystem services function, and GIS space analysis. In the following part this thesis takes Xingzi County as an example and analyses its situation and existing problems of land for ecological shelter zone. On the basis of the identification of severe disaster area through a filed survey and the designation of protection area via evaluation of ecosystem services function, the study is made on layout of ecological shelter zone with the analysis of ecological corridor and land patch. In the closing part of the thesis it elaborates on the significant role of land distribution of ecological shelter zone in maintaining the continuity and integrity of ecological network as well as its coordination with the distribution of industrial land and residential land.
