植物在采石矿坑棕地景观再生中的运用——以苏州乐园森林世界为例

Application of Plants in the Landscape Regeneration of Quarry Brownfield:A Case Study of Suzhou Paradise Forest World

苏州乐园森林世界位于苏州大阳山,场地在改造前为采石场,其地形地貌及植物群落遭到严重破坏。植物景观修复是采石矿坑棕地景观再生的关键。以苏州乐园为例,从生态修复植被选择原则、植被种类选择、特色化植物群落构建、边坡植被及水体生态植被恢复等方面,探讨了采石矿坑棕地景观再生中的植物景观营造策略,总结了在采石矿坑棕地生态改造实践中抗污染性和适宜性较强的植物种类和针对不同矿坑宕口空间地质条件的植物应用经验,并提出了在棕地改造中营构建适应性强、观赏价值高的植物群落,优化生境条件,注重植物的后期养护管理等建议。

Suzhou Paradise Forest World is located in Danyang Mountain,Suzhou.The site was a quarry before renovation,and its topography and plant communities were severely damaged.Plant landscape restoration is the key to the landscape regeneration of quarry brownfields.Taking Suzhou Paradise Forest World as a case study,this paper discusses the plant landscape creation strategies in the landscape regeneration of quarry brownfields in terms of the principle of vegetation selection for ecological restoration,the selection of vegetation species,the construction of specialised plant communities,vegetation on slopes,and aquatic ecological vegetation,etc.It also summarizes the plant species with strong anti-pollution and appropriateness in the practice of ecological renovation of brownfield landscapes as well as the application of plants in response to the different spatial geological conditions.It also suggests constructing plant communities with strong adaptability and high ornamental value,optimising habitat conditions,and focusing on the post-care management of plants in brownfield rehabilitation.
