摘　　要：近年来,填埋场开采成为填埋场生态治理的重要技术之一。然而,填埋场开采的可行性评估一直是制约填埋场开采项目的关键决策因素。以绍兴市越城区简易垃圾堆放场为例,基于该填埋场建设、运营概况及场地调查结果,从填埋场稳定化程度、环境风险等级和经济效益3个维度筛选并建立评估指标体系,采用层次分析法和综合评价法,构建了适用于城镇生活垃圾填埋场开采的可行性评估体系,为填埋场开采提供决策依据。结果表明:一期堆放场为中度稳定,低环境风险,低经济效益;二期堆放场为中度稳定,低环境风险,高经济效益。2期堆放场均具有填埋场开采的可行性,适合采用填埋场开采技术进行生态治理。In recent years,landfill mining is becoming one of the important technologies of landfill ecological management.However,the feasibility of landfill mining has always been a key decision-making factor restricting landfill mining projects.Taking a simple waste dump in Yuecheng District of Shaoxing as the example,based on the landfill construction,operation overview and site survey results,the evaluation index system was selected and established on three dimensions of landfill stabilization degree,environmental risk level and economic effect.And the feasibility evaluation system suitable for urban domestic waste landfill mining was constructed by using analytic hierarchy process and comprehensive evaluation method to provide decision-making basis for landfill mining.Results showed that:the first stage dump was moderately stable,with low environmental risk and low economic performance;the second stage dump was moderately stable,with low environmental risk and high economic performance.Landfill mining of both two stages dumps were feasible,and suitable for landfill ecological treatment.
