- Abstract:
-
Ecological issues on the drawdown zone of reservoir have widely gained attentions. Soil erosion on reservoir bank and non-point source pollution caused by the drawdown zone has threatened the reservoir operation and drinking water safety. The actuality and feature of the drawdown zone of reservoir in Shenzhen were analyzed in this study. The results showed that the vulnerable ecosystem and losing of amphiphyte were the key issues on drawdown zone repair. The ecological restoration technology of soil and water was proposed, which aimed at the area between the actual running level and the low level of reservoirs and the upper and lower 2 meters high tolerance range. And the ‘6 kinds of soil remediation system +6 amphibious plant community’ restoration scheme was proposed too, which devoted to repairing soil environment on bank slope by engineering measures, and selected suitable amphibious plant which have high afforestation survival rate and high vegetation coverage in the extreme environments. This study is expected to provide theoretical basis for ecological restoration on the drawdown zone of reservoir in red soil region of south China.
