Abstract: In May 2018, the Ministry of Ecology and Environment organized an action on fighting against environmental violations related to solid wastes, which is known as "Waste Clearance Action 2018", to ensure the ecological safety of the Yangtze River and curb the severe trends of solid waste illegal transfer and dumping. Based on the data collected duriing the implementation of "Waste Clearance Action 2018" from 11 provinces (province-level cities) in the Yangtze River Economic Belt, and using analytic hierarchy processes and linear weighted sum model, the effect of the actions on the rectification of environmental problems related to solid waste was evaluated. Four indicators of "clearing, tracing, punishing and blaming" were selected to build an assessment index system. Evaluation results show that the target of "Waste Clearance Action 2018" on rectification of environmental violations was highly fulfilled, with an overal rectification index of 0.85. Regionally, rectification levels of Anhui and Chongqing were the highest, with an index of 0.92 and 0.90, respectively, followed by Zhejiang, Shanghai and Jiangsu. According to the different categories of solid waste,environmental problems related to hazardous waste were most deeply remedied, with an index of 0.91, followed by general industry solid waste, mixed solid waste and other problems.

Key words: solid waste, illegal transfer, illegal dumping, Yangtze River Economic Belt, waste clearance action, rectification effect evaluation
