危险性废物场址的选择是一项十分复杂的系统工程，其影响因素具有信息不完全性、不确定性以及模糊性特点。以成都市为例，考虑地质构造、地理因素、地层岩性、水文地质条件、地表水系、地质灾害分布等因素，构建了多层次多目标方案优选评价指标体系；运用模糊数学综合评判改进模型对拟建成都市危险废物处置中心场址选择进行分析研究。结果表明，采用模糊数学改进模型进行废弃物场址选择的方法科学实用、操作简便，具有一定实际应用价值，可为相关工程提供借鉴。

The selection of hazardous waste disposal site is a complicated system engineering problem, and its influencing factors have the characteristics such as information incompleteness, uncertainty, and fuzziness. In this paper, a multi-level and multi-objective evaluation index system was developed in Chengdu City in consideration of geological structure, geographical factors, stratigraphic lithology, hydrogeological conditions, surface drainage, and geological disaster distribution. The fuzzy mathematical comprehensive evaluation method was used to analyze the selection of hazardous waste disposal site in Chengdu City. The results suggested that the fuzzy mathematical improved model is scientific and practical, easy to operate, and has certain practical application value, thus it can provide reference for related projects.
