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/m3 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.
