桂林市青狮潭水库消落带土壤侵蚀及其生态修复

Soil Erosion and Ecological Restoration on Water-level-fluctuation Zone of the Qingshitan Reservoir,Guilin,China

水库消落带是因调度等原因而形成的特殊区域,库水位周期性变化,波浪对库区边坡不断冲刷,土壤侵蚀十分严重。以桂林市青狮潭水库为背景,研究消落带的土壤侵蚀问题,提出:植被重建和恢复是最好的治理措施;建立一套合理的生态评价指标体系;对修复前后的消落带植被进行长期监测、对比和判断,对其成果进行有效、合理的评价,为水库消落带的生态修复提供参考。

The water-level-fluctuation of reservoir is a section of special region around the reservoir caused by reservoir＇s schedule. The water-level-fluctuation of reservoir is a wetting and drying area because of repeatedly periodic variation alternation of the water level ,therefore the soil erosion is serious. As an environment unit research on ecological restoration of soil erosion, can help to understand the among relationship the environment essential factor＇s and the synergy of law of development,and to provide the basis for the water-level-fluctuation on the rehabilitation and reconstruction. Taking Qingshitan reservoir as an example, this paper studies the water-level-fluctuation with soil erosion problems,takes the vegetation reconstruction measures ,and provide the reference of the ecological restoration in the water-level-fluctuation.
