基于分级加权法的城镇垃圾填埋场选址评价

城镇垃圾填埋场场址选择受经济、交通、气候、自然地理、环境保护、水文工程地质等诸多因素影响,是一项十分复杂的工程。结合环巢湖地区的实际情况,筛选各影响因子，最终确定符合该地区的评价体系。利用分级加权法进行垃圾填埋场选址评价,将研究区依次划分为适宜区、较适宜区、适宜性差区。根据已有规范对填埋场分区结果的验证，评估方法可行，评价结果合理，为安徽环巢湖地区垃圾填埋场选址提供了可靠的地学依据。

Site selection and evaluation of urban waste landfills based on hierarchical weighting method

The site selection of urban waste landfills is a very complex project affected by many factors such as economy, transportation, climate, physical geography, environmental protection and hydro-engineering geology. Based on the actual situation around the Chaohu lake in Hefei, this work screened the influencing factors, and finally determined the evaluation system suitable to this area. The hierarchical weighting method was used to evaluate landfill site selection. The study area was divided into suitable area, fairly suitable area and undesirable area in turn. According to the validation of the results of landfill zoning in line with the existing criteria, the evaluation method is feasible and the results are reasonable, which provides a reliable geoscientific basis for landfill site selection around the Chaohu lake of Anhui Province.
