摘　　要：以天津市海河教育园区为例,探讨土壤生态系统保育及修复在盐碱地园林绿化中的重要作用。所以,在已建园区,要时时监控土壤盐分的动态变化,通过合理的灌溉方式防控土壤次生盐碱化;在未建园区,应用基于土壤盐分空间分布的综合改土技术、自然景观的土壤排盐系统,来减少土壤盐害,并通过土壤生态条件的空间变异来优化植被类型分布及景观格局,最终实现生态功能的可持续化。With a case study of Haihe Education Park in Tianjin,the important role of soil ecosystem conservation and restoration in the saline-alkali soil landscaping was explored.Thus,it was important to constantly monitor the dynamic changes of soil salinity,to prevent and control soil secondary salinization through irrigation in the built park.In the unfounded park,to reduce soil salt damage,soil improvement technology was applied based on the space distribution of soil salinity,the soil salt drainage system of the natural landscape was also applied,and the regionalization of vegetation types and landscape layout should be optimized based on the result of the spatial variability of soil ecological conditions,ultimately,the sustainable ecological functions will be achieved in Haihe Park of Tanjin.
