| Application of Soil Ex-situ Amelioration Project in the Development of Large Landscape Sites in China—Taking the 10th China Flower Expo as an Example |

| Abstract: |
| 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 580,000m3
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. |
