- Abstract:
- Ecological suitability of the urban construction land is the fundamental way to alleviate the contradiction between the urbanization process and the land resources. According to the previous research, Analytic Network Process (ANP)-GIS integrated model was adopted to build up the ecological suitability evaluation of urban construction land in Changchun, combined with Changchun City’s natural, social, and economic characteristics. Finally,a visualized spatial distribution map(five suitability degrees) of ecological suitability of Changchun urban construction land was obtained. From the ecological suitability map, it can be seen that the most suitable land area for the construction land selection in Changchun is approximately 1 289.3 km2, the suitable area is 6 662.7 km2, the more suitable area is 9 461.4 km2, and the general suitable area is 2 848.2 km2, an unsuitable area 303.4 km2. The areas with high ecological suitability (the most suitable area and suitable area) for construction land in Changchun City are located in the hinterland of the Changchun region,where the degree of ecological suitability of natural, social, and economic indicators is relatively high. It indicates that the city’s future urban development and urban construction priorities can shift to the central region where ecological fitness is relatively high. The results showed that the reliability of ANP-GIS coupling model and provides the decision-making basis for Changchun’s construction land selection and Changchun city planning.
