Abstract In order to solve the uncertainty, ambiguity and randomness in the closure evaluation of the municipal solid waste landfill in Dagang District of Tianjin, combined with the actual situation of saline-alkali land in the arid area, the cloud model was introduced to evaluate the landfill site closure and determine the filling. The site level of the burial field. The weight of each level of the evaluation index of the landfill and the score of each level of the index are obtained by the reverse cloud generator to obtain the corresponding cloud model, and each level of the index is qualitatively and quantitatively analyzed, and the cloud model is evaluated for the landfill. The evaluation results are presented and an improvement plan is proposed. The cloud model provides a new method for the closure of saline-alkali landfills in arid regions.
