深圳城郊水库消涨带植被重建技术

城郊水库消涨带既要具有水源保护功能又要满足生态景观要求。在深圳市水源保护林建设专题研究的基础上,结合消涨带植物筛选试验成果,初步提出库区消涨带植被重建的技术体系。在正常水位线往下3 m内栽植乔木和草被,正常水位线往下3-6 m内栽植草被,同时结合生物排水沟、生态袋反坡梯地及反坡鱼鳞坑等辅助工程措施,可为水库消涨带生态重建提供途径。

Restoration technique of vegetation in the water level fluctuating zone of suburban reservoirs in Shenzhen

The water-level-fluctuating zone(WLFZ) of suburban reservoir should not only protect the water resources,but also meet the requirements of the ecological landscape.Based on the monographic study on Shenzhen's water conservation forest and the result of the screening test of the suitable plants for the WLFZ,this paper proposes the technical system of vegetation restoration in the WLFZ of reservoirs.Trees and herbaceous vegetation cultivated in normal water level line downward 3m,herbaceous vegetation cultivated in normal water level line downward 3-6 m,simultaneously a combination of the biological drainage ditch,the reverse terrace &; the reverse scale pit with eco-bag and other auxiliary engineering measures may provide ways for ecological reconstruction of the WLFZ of reservoirs.
