水库小流域生态修复对策初步研究

通过对试点水库生态现状调查分析、生态修复规划设计及技术方案的实施，对水库小流域水源涵养林、消落区植被、库尾湿地和水库水体生态修复进行了研究。针对小流域存在的林相结构单一、陡坡种果严重、人工林出现衰退、水土流失、面源污染等生态问题，初步实施了退果还林、人工纯林改造、苗圃建设、消落区植被营造、自然湿地恢复、水体污染控制等生态修复措施。

Studies on the Ecological Restoration Countermeasures of Small Reservoir Basin

In Maohu reservoir, by ecological investigation, planning of ecological restoration and its implementation, ecological restoration countermeasures were studied about water conservation forest of small reservoir basin, level-fluctuating zone vegetation, wetland in reservoir tail region, reservoir water body. In small watershed of Maohu reservoir, there were some ecological problems including the single structure of the forest, planting fruit trees in the steep regions, decline of plantation, soil and water loss, non-point source pollution. Aiming at these problems, some ecological restoration measures were carried out, including conversion of fruits land to forest, transformation of plantation, construction of nursery garden, building of level-fluctuating zone vegetation, wetland restoration and water pollution control.
