基于土壤重金属生态修复的社区花园植物景观设计

生活环境需求的提高要求景观绿地不仅要加强观赏性和体验性，同时要满足生态可持续的目标。城市更新下社区花园呈现迅速发展趋势，然而其景观设计与生态修复的研究缺乏理论基础。基于此，以土壤重金属污染为切入点，结合社区花园的景观特点和功能需求进行植物生态景观营造研究，提炼出基于土壤重金属生态修复的社区花园植物景观营造目标与原则。从社区花园的空间分区设计、植物群落层次、植物组团配置及重金属污染分级修复进行植物景观设计的探索，提出基于土壤重金属修复下的植物生态景观设计策略。以期为社区花园的长远发展和土壤重金属污染修复的景观营造提供借鉴。

Community Garden Plant Landscape Design Based on Soil Heavy Metal Ecological Restoration

The increasing demangd of living environment requires landscape green space not only to strengthen the appreciation and experience, but also to meet the goal of ecological sustainability. Community gardens develop rapidly under urban renewal, but the research of landscape design and ecological restoration lacks the theoretical foundation. Based on this, the paper takes soil heavy metal pollution as the starting point of community garden research, and extracts the target system and principle of community garden based on soil heavy metal ecological restoration. It explores plant landscape design, plant community group configuration, plant community level, and heavy metal pollution classification restoration, and forms a plant ecological landscape design module based on soil heavy metal restoration. It is hoped to provide reference for the long-term development of community garden and the landscape construction of soil heavy metal pollution restoration.
