- 摘要:
- 消涨带问题是国际上普遍关注的生态难题，水库消涨带所造成的库岸水土流失、面源污染等问题，对水库安全运行及水质危害明显。对深圳地区水库消涨带现状及生态特点进行分析，认为恶劣的库岸土壤环境和稀缺的两栖植物品种，是导致修复困难的核心因素。从水库消涨带可修复范围论证、水库消涨带类型划分着手，针对水库实际运行高水位和低水位及上下各2 m高差范围提出了消涨带水土生态修复技术体系，并提出了“6类整地+6种两栖植物群落”的修复模式，采用工程辅助措施营造岸坡植被生长的土壤环境，选择适生两栖植物进行造林复绿，以实现库岸造林的高成活率和植被的高覆盖度。该修复模式在深圳地区尚属首例，可为深圳及南方红壤地区水库消涨带水土生态修复提供参考。
- 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.
