基于模糊综合评价的多障碍因子建设用地空间拓展评价

Land Use Development Based on Fuzzy Comprehensive Evaluation for Multi-Obstacle Factor Construction Land Use

将模糊综合评价方法应用于土地供需紧张的福建邵武市建设用地空间拓展评价,根据研究区所处的自然地理环境及城市发展需求,利用专家知识、文献资料法提取研究区建设用地空间拓展障碍因子,并将障碍因子归类分为土地资源适宜性障碍因子、生态安全与生态服务障碍因子和地质灾害风险障碍因子。建立模糊综合评价指标体系及模糊综合评价模型,对研究区进行建设用地空间拓展模糊综合评价,得到研究区建设用地空间拓展适宜性程度空间分布状况,为海西地区的城市发展空间规划和优化配置提供数据参考。

Fuzzy comprehensive evaluation is a method of making comprehensive decision-making for the purpose of evaluation in a fuzzy environment. Considering influence of many factors,the fuzzy comprehensive evaluation method is used to evaluate the spatial development of construction land in Shaowu,Fujian Province,which is based on the tight supply and demand of land supply and demand. Regarding natural geographical environment and urban development needs of the study area,this paper uses expert knowledge and literature data to extract the spatial expansion barrier,and classify the barrier factors into land resource suitability disorder,ecological security and ecological service obstacle factor,and geological hazard risk factor. The fuzzy comprehensive evaluation index system and the fuzzy comprehensive evaluation model are established,and the fuzzy comprehensive evaluation of the land use space of the construction area is carried out. The spatial distribution of the spatial degree of spatial development of the construction land in the study area is obtained,which is the spatial planning and optimal allocation of urban development in the Economic Zone on the Western Coast of the Taiwan Straits.
