文摘On the basis of deeply understanding the domestic existing evaluation method of ecological restoration for soil and water conservation, under the premise of analyzing characteristics of current commonly used evaluation index of ecological restoration, based on the actual situation in Ningxia Hui Autonomous Region, taking objectivity, independence and operability as the principles, nine evaluation indexes were selected, and a set of comprehensive evaluation method of ecological restoration for water and soil conservation based on AHP was constructed. The hundred mark system corresponded with ecological restoration level, and the weight of each index in evaluation system was calculated according to comparison matrix constructed by frontline workers of soil and water conservation. The method could be used to determine difficult degree of restoration of the disturbed and destroyed ecosystem and the rationality of ecological restoration for soil and water conservation.
