Zhang Liqian, Cai Jianming


This paper studies the Analytic Hierarchy Process (AHP), and puts forward the ecological environment AHP index of Xining City accordingly. By using GIS technology, Five-Laps-linkage Thought and Traffic Lights Principle, the writer makes a qualitative and quantitative analysis of Eco-environmental Quality, and gives an accurate and objective assessment to the Eco-environmental Quality of Xining City. These assessments would help a lot for government to determine the ecological environment protection policies. Studies show that, social circle, hydrosphere, atmosphere, lithosphere and biosphere make a decline in turn influence to Xining Eco-environmental Quality assessment, and hence the mean, social circle is the strongest influence to Xining Eco-environmental Quality. For a long time, the ecological environment in this area is in a precarious position; as a result, we should prevent to make aggressive decision during the urbanization, value the quality instead of quantity. Focus on the development of eco-industries; and gradually improve the Eco-environmental Quality in some area where is not so good; using the coordinative development principle between resources, environment and economy to guide regional urbanization.
