Abstract
By combining expert consultation and field investigation, an evaluation system, consisting of 29 indices in 5 aspects of water safety, water ecology, water management, water landscape and water culture, was established for water ecological civilization construction in coal mining subsidence areas. The weight of the indices was determined using improved group-decision fuzzy analytic hierarchy process and fuzzy mathematical method, and their score was determined according to their value before the pilot and the value at the end of the pilot. Combined with the weight, the actual score of the indices was obtained. Finally, a comprehensive index of water ecological civilization in coal mining subsidence areas was obtained. Through the weight and score of the indices, the construction status, existing problems and future tasks of coal mining subsidence areas were analyzed, in order to provide a reference for the region to further clarify the direction and key tasks of water ecological civilization construction.
