Abstract

Disclosed is a method for vegetation recovery in garbage burying field using covering soil modified from urban sludge, comprising following steps: using the sludge of urban sewage factory as covering soil modifier for garbage burying field, adding amendment into the sludge, and mixing them uniformly with the covering soil to produce modified covering soil; covering the modified covering soil onto the surface of the covering soil in garbage burying field, smoothing without compaction, planting resistant plants adaptive to the garbage burying field environment. The method disclosed can accelerating vegetation recovery in garbage burying field obviously, and shorten vegetation recovery course; solve the problem of large area of dilapidated ground in garbage burying field, tight covering soil resource, and environmental contamination and landscape ecology sever damage, so as to economize in large amounts of ground resource and bring appreciable economic profit.
