开发建设项目施工中表土资源的保护与利用

Conservation of Surface Soil Resources in Development and Construction Projects

表土是非常珍贵的不可再生资源,表土剥离与回填能够节约利用资源、保护生态环境。目前表土处置过程中存在表土大量流失、表土防护不当导致地面植被稀少、地表裸露等问题,并对此提出表土剥离原则及厚度,探究表土堆放方式与保护措施,指出可采用平面均匀法、圆形点状法、坑状法、带(条)状法等4种回填方式对表土进行回填利用,以期强化对表土的保护及利用,旨在最大程度保护表土资源,发挥其重要效益。

Surface soil is a very precious non-renewable resource. Surface soil stripping and backfilling can save resources and protect the ecological environment. Through explaining the value of surface soil resources and the problems existing in the disposal process, the principle and thickness of surface soil stripping are explained in this paper, the ways of surface soil stacking and protection measures are explored, and different ways of surface soil backfilling utilization are also discussed, with a view to strengthen the protection and utilization of surface soil, in order to maximize the protection of surface soil resources and give play to its important benefits.
