摘要
目前中国对植物园土壤改良的研究大多倾向于化学性质的改良,对物理结构的关注较少。大多数植物园在建设及运营过程中土壤质量均存在着不同程度的问题,影响着植物的良好生长和生态效益的发挥。通过辰山植物园土壤改良修复工程的研究实践,针对土壤理化性质退化、排水不畅等问题,运用植物原/异位保护、土壤配方改良和排水系统优化等技术关键,有效改善改良区内的土壤理化性状,优化排水系统,并提升专类园植物景观和生态环境,为同类植物园或绿地系统内土壤的改良修复提供有力的技术支撑与实践指导。
At present, the research on botanical garden in China is more inclined to improve the chemical properties of soil, but has been paid little attention to the improvement of physical structure. However, in the course of construction and operation, most of the botanical gardens＇ soil is destroyed in varying degrees, which will affect the plant landscape and ecological benefts. In this paper, through the analysis of the key technologies applied in soil remediation of Shanghai Chenshan Botanical Garden, aiming at the problem of the physical and chemical properties of soil degradation, poor drainage, the paper adopts plants in-situ/off-site protection, soil transplantation, the improvement of soil formula and underground drainage system optimization practice, thus improves the overall quality of the soil improvement in the region, and provides technical support and practical guidance for the same kind of powerful botanical garden or the soil of green space system in remediation.
