- Abstract:
- In view of the existing problems of water system in karst mountain areas, the construction strategy of sponge system in karst mountain areas was proposed according to the local natural environment characteristics and economic development. A combination weighting and cloud model evaluation method was proposed to truly reflect the comprehensive benefits of the sponge system. Firstly, an evaluation system reflecting the characteristics of sponge system in karst mountain areas was constructed. Then, analytic hierarchy process and entropy weight method were used to determine the weight of evaluation indexes. Finally, cloud model and similarity calculation were introduced to determine the evaluation level. The sponge system in karst mountain area, Jiuchi Village, Houping Town, Baokang County, Hubei Province, was constructed and its comprehensive benefit was evaluated. The sponge system in karst mountain area obviously improved the local ecological, economic and social benefits, indicating that the combination weighting and cloud model evaluation method was accurate, objective, feasible and effective.
