基于LSP方法的山地型矿业城镇空间拓展土地适宜性评价

Land Suitability Evaluation for Space Expansion of Mountainous Mining Towns Based on LSP Method

以北京市门头沟区为研究区域,采用LSP方法构建了山地型矿业城镇空间拓展的土地适宜性评价指标体系,并设置了4个聚合情景进行了实例验证。结果表明:LSP方法中强制性指标与可选指标的组合比单一指标体系更适合山地型矿业城镇空间拓展用地评价工作;选择不同的加权模式、不同的LSP聚合器可产生不同的LSP聚合结构情景来支持评价者的不同决策;情景2评价出的优化建设区、适宜建设区与现状建设用地在空间分布上基本吻合,且可以满足门头沟区未来拓展城镇空间的用地需求,更符合门头沟区的发展。

Taking Mentougou District of Beijing as the research area,the land suitability evaluation index system for spatial expansion of mountainous mining towns was constructed by LSP method,and four aggregation scenarios were set up to verify the results.The results show that the combination of mandatory indicators and optional indicators in LSP method is more suitable for the evaluation of spatial expansion land use of mountainous mining towns than a single index system.Different LSP aggregation structure scenarios can be generated by different weighting modes and different LSP aggregators to support different decision-making of evaluators.The optimized construction area and suitable construction area evaluated in scenario 2 are basically consistent with the current construction land in spatial distribution,and can meet the land demand of urban space expansion in Mentougou District in the future,which is more in line with the development of Mentougou District.
