中国黄土丘陵区水土保持与生态恢复模式
Models of soil and water conservation and ecological restoration in the loess hilly region of China
摘要
Abstract
Ecological degradation characterized by severe soil erosion and water loss is the most imposing ecological-economicissue in the Loess Hilly Region; the soil and water conservation (SWC) and ecological restoration are crucial solutions to thisissue. It is of importance to explore SWC models for ecological reconstruction compatible with local socioeconomic andenvironmental conditions. The paper reviewed on SWC and ecological rehabilitation researches and practices and mainly concerned on eight small-scale (small catchments) models and Yah'an Meso-scale model in the Loess Hilly Region. To evaluatethe environmental and socioeconomic impacts of these models, their validities were examined using the participatory ruralappraisal. The results indicated that SWC and ecological restoration at different scales have played important roles both in localeconomic development and environmental improvement and provided an insight into sustainable economic development on theLoess plateau in the future. Furthermore, this paper strengthens our belief that, under improved socioeconomic conditions,SWC and ecological reconstruction can be made sustainable, leading to a reversal of the present ecological degradation.关键词
