摘要
利用层次分析法开展武汉都市发展区地下水源热泵适宜性评价分区,根据武汉都市发展区地质环境条件,选取含水层出水能力、渗透系数、有效含水层厚度、含水层回灌能力、地下水位埋深、地下水位动态变化、地下水质量、结垢情况、开采模数、水位下降引起的环境地质问题（地面塌陷、沉降）和成井造价等11项作为评价指标。采用1~9标度法和专家打分确定权重,建立评价体系和综合指数评价方法。通过评价结果综合分析进行了适宜性分区,分区结果为地下水源热泵适宜区主要为长江、汉江一级阶地前缘—中缘;白沙洲地区、中南轧钢厂等地下水禁采区、汉南岩溶发育区、一级阶地后缘地区及部分隐伏岩溶区为不适宜区,为地下水源热泵的利用提供科学依据。
Using analytic hierarchy process to divide the suitability of groundwater heat pump in Wuhan urban development area,the paper selects aquifer effluent capacity,permeability coefficient,thickness of effective aquifer,aquifer recirculation capacity,groundwater depth,dynamic cjange of groundwater level,water quality,exploitation parameter,karst collapse settlement for water table depression and the cost of well as evaluation index. Using 1-9 scaling method and expert evaluation method to determine weight,establish evaluation system and composite index evaluation method. The evaluation result is that the suitable area include the front to middle of first grade terrace of Yangtze River and Hanjiang River,Baishazhou area,South-Central steel rolling factory and other prohibition exploitation of groundwater area,karst development area in Hannan,the background of first grade terrace,part of Covered Karst area are unsuitable areas of groundwater heat pump.
