Ecological sensitivity analysis and assessment of Kubuqi desert based on GIS
Ecological sensitivity assessment is an important means and link of regional ecological environment protection and construction work.Taking Kubuqi desert as the research site,six evaluation factors including elevation,slope,slope direction,water buffer,vegetation coverage and land use type are selected to construct the ecological sensitivity assessment system of Kubuqi desert in the paper.The ecological sensitivity of Kubuqi desert is analyzed and evaluated by using analytic hierarchy process and GIS technology,and five sensitivity levels are divided.The results show that the overall ecological sensitivity of Kubuqi desert is low,mainly mildly sensitive.Vegetation coverage affects the most,followed by land use type.Insensitive,mildly sensitive,moderately sensitive,highly sensitive and extremely sensitive are 27.37％,46.66％,22.00％,2.20％and 1.77％of the Kubuqi desert area,respectively.The areas with high sensitivity are mainly distributed in the northern end of Kubuqi desert,mainly lakes,rivers and vegetation reserves.The research results could provide some scientific suggestions for the regional ecological environment construction and protection work in the Kubuqi desert.
