摘要
选择侵蚀山区有代表性的小流域——铁岭东沟小流域为研究对象,采用综合效益系数法和综合功能系数法,对水土流失综合治理前后小流域生态系统进行了综合效益和综合功能评价。通过分析发现,所采用的方法揭示了小流域水土保持生态建设治理项目的单项效益和综合效益,说明这种方法适用于复杂的侵蚀山区生态经济系统评价。
Taking the Donggou watershed as a small representative watershed for the mountainous area and using the integrated benefit method and the comprehensive function method, ecosystem of the small watershed is evaluated for the integrated benefits and comprehensive functions before and after soil erosion programs are implemented. Analyses indicate that the used methods can describe the single benefit and integrated benefit resulted from the projects of soil and water conservation and ecological construction in small watersheds, and are suitable to ecological economic system appraisal in the complex eroded mountainous area.
