摘　　要：土壤是植物生长的基础,土壤条件的优劣对城市生态环境建设至关重要,而目前绿化土壤改良工作存在两级分化的问题。以上海临港新片区茉莉路景观提升工程为例,针对土壤存在的强碱性(pH值均值高达8.76)、有机质含量低(均值仅7.55 g/kg)、物理性状差(土壤密度和非毛管孔隙度均值分别为1.53 Mg/m^(3)和3.43%)的问题,因地制宜地制定改良配方、筛选和控制改良材料质量、资源化利用绿化废弃物,指导土壤改良施工有序开展;结合地上地下排水系统和土壤天然海绵体功能有效地解决土壤积水问题,为植物生长营造良好的地下环境。同时分析目前绿化土壤改良技术中存在的关键问题与解决措施,探讨土壤改良技术在景观提升中的生态作用,以期为相关的景观改造及城市绿地生态环境建设管理提供科学依据。Soil is the foundation of plant growth,and its quality is crucial to the construction of an urban ecological environment.But there are some different problems during the construction of soil amelioration.Therefore,an experiment was conducted on Moli Road in Shanghai Lingang New Area,in which there are lots of soil problems,such as strong alkalinity(the average pH is 8.76),low organic matter content(the average soil organic matter content is 7.55 g/kg),poor soil physical property(the average of soil density and non-capillary porosity is 1.53 Mg/m^(3) and 3.43%),etc.The objective of this study was to elucidate how to take effective amelioration of soil to improve the greening landscape in the study area.The soil amelioration formula selected the optimal materials for soil amelioration,and greening waste utilization were taken to make sure the construction of soil amelioration,combined the above-ground and underground drainage system and used the sponge function of the soil itself to solve the poor drainage capacity to maintain the better environment for plant growth.Meanwhile,analyze the key issue of soil amelioration at present and finally take reasonable measures to solve it.Taking into the results of this study,we can draw the conclusion that the application of soil amelioration has significantly positive effects on landscape restoration,which can provide a scientific basis for high-efficient restoration and optimized management in an urban greening environment.
