摘要: 以山东省济宁市大运河生态经济区为例,探讨了煤炭资源型城市建设用地适宜性评价的指标体系、评价模型以及GIS技术支持下的分析评价方法。选取自然因素、社会经济因素、生态安全因素3方面8个单因子构成该研究区适宜性评价指标体系,利用模糊层次分析法确定指标权重,基于多因素叠加分析和GIS空间分析方法,设计了四种煤炭塌陷的未来情景,进行了研究区城市建设用地适宜性单因子评价和四种情景下的综合评价。结果表明:情景1(现状塌陷)中,可高强度开发(很适宜)的用地为7476.9hm2,占总面积的32.6%;较为适宜建设的土地为4967hm2,占21.6%;较不适宜与不适宜的土地共占33.49%。情景4(最终塌陷)中,适宜用地为4084.21hm2,占总面积的17.79%。较为适宜的土地为4511.56hm2,占19.65%。较不适宜与不适宜的土地共占53.44%。随着采煤塌陷面积的不断扩大,适宜建设的土地急剧减少。今后应根据不同的塌陷区现状,进行不同形式的改造、更新和再利用,引导形成集约高效的新型生态城区。

Abstract: With the speeding up of China's urbanization in recent years, some problems have emerged due to urban construction such as the conflicts between land and people, safety for human settlement, eco-environmental issues, and so on. Urban construction land suitability evaluation has aroused more attention. The rise of resource-based cities is associated with resource development. The conflict between coal mining and urban development is the long-term contradiction of coal resources cities. In view of this, the Grand Canal Ecologic and Economic Area in Jining city is taken as an example in this paper, and the index system and evaluation mode and GIS methods about the coal resources cities of land suitability evaluation are discussed. Firstly, the suitable evaluation index system contains eight factors in three aspects of natural factors, socio-economic factors and ecological safety factors. And then, using AHP to determine weights, by multivariate analysis and GIS spatial overlay analysis, four future scenarios of coal collapse are designed, and a single factor score map and the integrated evaluation map under the four scenarios are made for the study area of urban construction land suitability evaluation. Finally, evaluation results are analyzed. In addition, some countermeasures of urban development are put forward.
