- 摘要:
- 通过对水库运行后消落带的特点进行分析，预测了金沙江干热河谷水电站水库建成后，由于水库水位的涨落形成的消落带，可能会带来环境污染、土壤侵蚀和水土流失、生态系统被破坏、诱发地质灾害等生态环境问题。通过实地调查、现场试验和对三峡等消落带的分析研究，确立了电站水库蓄水后消落带应该具备的立地类型和消落带区域在水库建设过程中应相配套的工程措施；以及在水库蓄水后水面以下0～5m应种植杨柳等高大乔木；5～15m应种植根系发达的草本，如香根草等；15～30m应以苏丹草、稗草、小米草等饲草为主。
- Abstract:
- In this paper,characteristics of level-fluctuating zone is analyzed after running the reservoir,because of the formation of the level-fluctuating zone by the reservoir water level fluctuation,which may resulted to some ecological environment problems such as the environmental pollution,soil erosion,ecosystem damaged,geological disasters and so on.By surveys,field tests and analysis of level-fluctuating zone Three Gorges area,site type and engineering facilities of level-fluctuating zone region are established after water reservoir.Moreover,some measures are provided such as planting willow below 0～5m of water level,planting Vetiver below 5～15m of water level,planting Sudangrass,barnyard grass,millet grass below 15～30m of water level.
