余泥渣土受纳场景观恢复设计探讨——以深圳市下围岭余泥渣土受纳场为例

通过景观恢复措施,营造自然景观,解决深圳市下围岭的余泥渣土受纳场封场后人工化痕迹明显,与周边景观不协调的问题。该项目景观定位为常绿落叶混交景观林,以花海、色斑、丰富的季相变化为景观特色,将山体分为上、下部两块,分别营造道路原野型生态林景观区和城市背景型生态林景观区,形成＂小群落大混交＂和＂大群落大混交＂两种形式。综合考虑植物花期、色彩差异体现景观林的季相和色彩变化,大尺度营建特色鲜明的森林景观斑块,丰富林际线和季相景观,采用群落混交的方式配置植物,并利用生态挡渣坝、坡地覆土、土壤改良、绿化浇灌措施最终营造远、近景自然交融的景观恢复效果。

Discussion on Landscape Restoration Design of Construction Waste Treatment Field

By landscape restoration design and through creation of natural landscape,obvious artificial traces in construction waste treatment field on lower Wei Mountain of Shenzhen City had been eliminated and the treatment field became coordinating with surrounding landscape.The landscape had been identified as evergreen deciduous mingled forest,characterized by flower sea,colored patches and rich seasonal change.The mountain had been divided into upper and lower part to build ecological forest zone of field type and ecological forest zone of city background type respectively,forming"small community and large mingled forest"and"large community and large mingled forest".By taking plants'flowering period and color difference into comprehensive consideration,seasonal and color change of landscape forest would be manifested,forest landscape patches with distinctive characteristic would be built in large scale,and forest line and seasonal landscape would be enriched.By adopting mixed forest,and using ecological dam,coverage on sloping field,soil reclamation and greening irrigation,landscape restoration effect of integration of close view and distant view would be created finally.
