Analysis On Changes Of Land Use And Their Ecological Environment Response In Ebinur Lake Basin

To demonstrate effect of land use changes on ecological environment of Ebinur Lake Basin in this18years of late base on study land use dynamic state change, quantitative analysis on the effect of the time and space structure of land use conversion, ecosystem-value and mode of land use transform on region’s quality of ecological environment, use correlation analysis to demonstrate Relations of land use and ecological environment in Ebinur Lake Basin for1990-2008years.The result revealed that:Firstly, Ebinur Lake Basin has take on a situation that acreage of city and village industrial land and plowland such obvious change scope, acreage of lea land change quantity is the least, acreage of unused land decrement is the most, acreage of the others land tape increased; Secondly, from the landscape pattern change, the degree of separate lower step by step, the degree of pieces rise before went down, diversify index and degree of well-distributed rise quickly before went down swift in Ebinur Lake Basin; Thirdly, it’s conclude that region’s surface area of land use type which have high value of ecosystem services enlarge can improve quality of ecological environment in whole region base on calculated value of ecosystem services, but ecosystem services still fragile and forward to increase; Fourthly, it is reflect that ecological environment worsen and quality of ecological environment lower when type of land use transform has happened, because of acreage of farmland, woodland, lawn and water area reduce, construction-land enlarged.
