青海省黄河流域生态修复适宜性的初步探讨

A Tentative Discussion of Feasibility of Ecological Recovery Along the Yellow River Valley Within Qinghai

青海省黄河流域不仅是黄河发源地,也是黄河流域主要产流区和水量的供给区之一,对黄河流域水资源可持续开发利用具有决定性影响。由于地处特殊地理位置和不利自然条件,生态修复尤为重要。生态修复范围可分为黄河河源区生态建设区、东部黄土高原水蚀生态建设区,通过对分区水土保持生态修复适宜性初步分析,认为水土保持生态修复是改善青海省黄河流域生态的有效途径之一。

The Yellow River valley within Qinghai is not only the headwaters area,but also one of key water-producing areas and water-supplying areas of the whole valley,having a decisive role in the sustainable development of water resources. Owing to special geograpical location and adverse natural condition,the ecological restoration is exceptionally essential. The ecological recovery area comprises the Yellow River headwaters area and the water erosion area in the east Loess Plateau. The feasibility of ecological recovery through zonal conservateion is analyzed and it is one of the effective approaches to the ecology along the Yellow River valley within Qinghai Province.
