武汉市建筑垃圾处理厂的选址适宜性评价

开展适宜性评价有助于建筑垃圾处理厂科学、合理选址。选取土地规划、人口密度、距新老城区距离、风向影响、地基承载能力作为选址适宜性影响因子；采用层次分析法（AHP）构建选址适宜性评价体系；基于ArcGIS对武汉市开展建筑垃圾处理厂选址适宜性评价。结果表明:武汉市适合建厂的区域主要分布于黄陂区的南部和中部、新洲区的西南部和中部、江夏区的北部和中部、东西湖区的东部和东南部、蔡甸区的东北部、洪山区的北部和东北部。研究结果可为城市建筑垃圾处理厂选址提供参考。

Suitability Evaluation of Site Selection of Construction Waste Treatment Plant in Wuhan

Suitability evaluation is scientific and reasonable for the site selection of construction waste treatment plant. According to literature review，land planning，population density，distance between the new and old urban areas，impact of wind direction and foundation bearing capacity were selected as the influencing factors for site selection. Analytic hierarchy process （AHP） was used to establish the suitability evaluation system of site selection. Based on ArcGIS，the suitability evaluation of site selection of the construction waste treatment plant in Wuhan was performed. The results show that the suitable areas for construction waste treatment plants in Wuhan are distributed in the southern and central area of Huangpi District，the southwestern and east area of Xinzhou District，the northern and central area of Jiangxia District，the eastern and southeastern area of Dongxihu District，the northeastern area of Caidian District，and the northern and northeastern area of Hongshan District. The research results can provide a reference for site selection of urban construction waste treatment plant.
