A landfill location method is proposed based on improved AHP and gray correlation model to improve the main deficiencies on influencing factors and expert weights of landfill location. Location influencing factors covering four categories are put forward as transportation conditions, environmental conditions, construction conditions and economic conditions. According to the preliminary investigation, laws, regulation and the Delphi methoc, the location factors are divided into fuzzy value and exact value and different methods are applied to the treatment. The Delphi method, improved AHP and gray correlation model are integrated into complex systems evaluation, and the expert weights are thought carefully over determining the weight of location factors. A case study is introduced to validate this method.%针对卫生填埋场选址方法在选址影响因素特性和专家权重处理方面的不足，提出了基于改进层次分析法与灰色关联模型的城市固体废物卫生填埋场选址方法。该方法主要特点：根据前期调查、法律法规及德尔菲法提出了涵盖交通运输条件、环境保护条件、建场条件和经济条件4类选址影响因素；将选址影响因素分为模糊数值和精确数值两种属性类别并采用不同方法进行处理和综合评价，并在确定选址影响因素权重时考虑了专家权重的不同。通过示例对选址评价模型的应用方法进行了具体说明，证实了其可行性。
