| Abstract: | This paper constructed the urban eco-sensitivity comprehensive evaluation model for Nanning through establishing the eco-sensitivity evaluation factor system and identifying the weight of evaluation factor using AHP method. It produced the evaluation result map using the spatial overlay and analysis function of ArcGIS. Then it analyzed the spatial distribution characteristics of urban eco-sensitivity in Nanning based on the result map,and presented relevant countermeasures to set up ecological security strategy and provided important decision making support for the sustainable developing of the urban ecological environment and social economy in Nanning. |
