Study On The Construction Of Rural Settlement Landscape In Eastern Jilin Province Under The Ecological Security Pattern

Jilin province is rich in ecological resources,especially the east natural condition is superior,because is located in the changbai mountain forest area,as a national important strategy resource reserves and ecological security barrier,ecological protection is good for a long time.But with the rapid development of China's urbanization and new rural construction to promote the rural settlement landscape,great changes have taken place in eastern jilin province ecology presents the natural substrate,less of woodland resources,the water environmental pollution and other issues.It is of great importance to coordinate the contradiction between rural settlement development and ecological protection and control the construction of rural settlements in eastern jilin province.Based on rural settlements as the carrier,in the eastern part of the jilin province forest ecological as the research object,combined with the theory of landscape ecological security pattern,using the RS and Arc GIS technology,as a typical sample of yanbian Korean autonomous prefecture,baishan and tonghua elevation,slope,vegetation,drainage,farmland and woodland ecological single factor analysis,so as to build the landscape ecological security pattern of the eastern jilin province.First,the natural conditions in east of jilin province,based on the research of ecological evolution and characteristics,by using landscape index method to quantify the typical villages,and combined with field survey summarizes the present situation of the eastern landscape ecological pattern.Secondly,by discriminating the single factor of eastern jilin province,an evaluation system was established,and the eastern ecological security pattern was divided into high,middle and low ecological security zones by Arc GIS spatial analysis.Finally,based on the characteristics of regional division three ecological function areas: tumen river ecological function of water conservation,the source forest conservation ecological function areas and the yalu river region construction ecological function areas,put forward the developmentstrategy of regional ecological,guide the rural settlement construction and development in the future.The aim of this paper is based on a typical eastern country settlement landscape characteristics and present situation analysis,combing the characteristics of the rural settlement landscape,supplement and perfect the rural settlement landscape in different regions theoretical research system,provides new theoretical support for development of rural settlements construction and planning guidance.At the same time,through the quantitative study of eastern jilin province ecological landscape,ecological zoning guidance strategy is put forward,and then promote the ecological sustainable development of jilin province,provide the theory and method for the development of jilin province rural settlements.
