改进层次分析法下的浅层地温能适宜性评价

Assessment of suitability of shallow geothermal energy based on improved analytic hierarchy process

传统的层次分析法(AHP)在划定权重时,赋值的跨度较大,很难对影响因子间的相对重要性进行数值的量化,因此采用改进的层次分析法,运用"三标度"法进行因子间的重要性量化,对于因子间的合理赋值取得了明显的效果。运用ArcGIS的空间分析模块,根据获得的权重值对研究区进行浅层地温能适宜性分区评价,经实际工程验证,确定评价结果的准确性。

It is difficult to quantify the values of impact factors relative importance because of the large range when using traditional Analytic Hierarchy Process（AHP） to designate weights.Therefore,the improved Analytic Hierarchy Process which is also called ＂Three-scale＂ method is used to quantify the importance between different factors.A significant effect is achieved when using the methed to evaluate the factors importance legitimately.According to the impact factors weights,the special analysis module in ArcGIS is used to classify the suitability evaluation of shallow geothermal energy in the study area.After the practical engineering verification,to determine the accuracy of the evaluation results.
