| Comprehensive Benefit Evaluation of Rocky Desertification Control in the Typical County of Karst Fault Basin: A Case Study of Jianshui County, Yunnan Province |
| To investigate the contribution of the Comprehensive Rock Desertification Control Project to environment, the authors set up a comprehensive efficiency evaluation index system of the Comprehensive Rock Desertification Control Project. Principal component analysis method and entropy method were used to evaluate the comprehensive efficiency of Rock Desertification Control Project of Jianshui, which is a typical county in 13th Five-Year Plan in the Comprehensive Rock Desertification Control Project. The efficiencies of three types, ecological efficiency, economic efficiency and social efficiency, were evaluated. The results are as follows: ①During 2007–2013, comprehensive benefits and ecological, economic, and social benefits showed an upward trend. However, the increasing range began to decrease from 2013. ②Positive sustainability appeared in the comprehensive benefits and economic, social and ecological benefits of rocky desertification control in Jianshui County. And the economic and ecological benefits in sustainability were significantly higher than the social benefits. Among the economic benefits, the rise of grain output was obviously lower than the increasing trend of the proportion of the secondary and tertiary industries in the total economic output and the income of cash crops. In Summary, from the beginning of the control of rocky desertification in Jianshui County, the industrial structure has been improved, the area of rocky desertification has been reduced, and the satisfaction of residents has been improved. |
