摘　　要：从土壤工程入手,针对土壤质量制约中国生态景观质量提升且土壤工程系统研究报道较少的现状,以第十届花博会现场实施的土壤异位改良工程为例,分析其设计愿景和现状矛盾,总结出表土收集和再利用、土壤改良配方设计、土壤生产基地建设和运营、地形再建和改良种植土回填四大关键步骤和技术要领;并通过土壤质量主控指标全过程监控,确保58万m^(3)种植土成品的生产质量,为花博会的顺利召开和高品质景观营建提供了技术保障。分析了土壤异位改良工程符合我国的发展需求,阐述其兴起的时机已成熟,并提出将其作为专项实施工程,依托其快速成景的特点,建立适宜我国不同场地应用的技术体系,以及建立长期定位监测研究4条建议,以期为土壤异位改良工程在我国大型景观开发场地中的应用提供借鉴,丰富我国的土壤工程学技术。In response to the current situation that soil quality restricts the ecological landscape quality and few studies address the soil engineering system in China,this study,starting with the soil engineering,analyzes the contradiction between design vision and current situation on the 10th China Flower Expo.This article summarizes four key steps and technical essentials for the ex-situ soil amelioration project,which have been carried out in the field of the exhibition.Those steps included topsoil collection and reusing,formula design for soil amelioration,establishment and operation of soil production bases,and terrain reconstruction and backfilling of the ameliorated planting soil.The main control indicator of soil quality in the whole project was monitored to ensure the production quality in 580,000m^(3)of high-quality planting soil.The quality control could provide technical guarantee for smooth holding of the exhibition and construction of the high-quality landscape.It analyzes that the soil ex-situ amelioration project meets with the development demand of China and the opportunity for application is coming.This study proposes four pieces of countermeasures of implementing as a special engineering project,relying on formation of rapid scenery,establishing technique system for application in different sites,and performing research on long-term positioning and monitoring,which would provide experience for the application of the soil ex-situ amelioration project in large-scale landscape development sites in China and enrich the soil-engineering technology.
