The evaluation of the integrated ecological environment status of Shizuishan City based on Analytic Hierarchy Process

Distinguish the importance degree of the elements affecting the ecological environmental status of ShiZuishan City by expert scoring, establish the evaluation index system and calculate the weight of each element contributing to affect the quality of the ecological environmental status based on the Analytic Hierarchy Process. The analysis result shows that the most important four elements affecting the ecological environmental status of ShiZuishan City are as follows: vegetation cover condition, geomorphological Characteristics, soil erodibility and pollution status. Sketch out the integrated geographical union using the remote sensing image, endow the attribute to every integrated geographical union according to the basic materials, and then, make the attribute values being dimensionless, assort the attributes into several classifications, finally, use the modeling tool in Arctoolbox module of the ArcGIS9.2 software to build weighted comprehensive evaluation model, draw the final evaluation map of the integrated ecological environment status of Shizuishan city by stacking the four elements weighted. The ecological environment status of Shizuishan City is graded into four ranks, excellent, good, general and worse. Based on the comprehensive evaluation result, putting forward some suggestions to Shizuishan City on promoting sustainable development of economy and society, for example, suggest Shizuishan City to accelerate the closing of the high water consumption, high energy consumption and high pollution enterprises, lay the development emphases on PingLuo country, construct tourism facilities around the lakes and wetlands within limited, prohibit exploiting the nature reserve on the Ho-lan Mountain and cancel the coal mines out in the nature reserve.
