综合生态防护工程技术在改善城市地景中的应用

Application of Integrated Bioengineering Protection Technique to Improvement of City Landscape

城市地景建设是改善城市人居环境和防治水土流失的重要内容。深圳市近年来开展了开发区大面积水土流失治理、裸露山体缺口的综合整治和水源保护林工程建设3个阶段的生态景观恢复工作。对各阶段城市地景生态防护工程技术进行了研究,并总结出生物砖排水沟、直接喷播绿化、喷混植生、人工植生盆(槽)、挂笼砖、景观再造法、生态袋护岸和水库消落带生态防护等关键地景生态防护工程技术,以达到城市地景生态近自然恢复的目的。

The city landscape building is of an important part to improve urban residential environment and control the soil and water loss.Shenzhen Municipality has done much work on the ecological restoration of landscape in the past decade,which includes three stages: the control of soil erosion happened in the developing areas,the comprehensive ecological construction of exposed hill pits and the construction of protective forests for water resources.Based on many years research in the urban landscape ecological restoration,the paper summarizes key bioengineering techniques for city landscape protection with the purpose of the natural ecology restoration,which includes biological brick drainage canal,hyproseeding,spray sowing,artificial groove for planting,brick of culture substratum,ecological-type bank revetment and the ecological protection technique of reservoir falling zone.
