VEGETATION SURVEY FOR ENVIRONMENTAL MONITORING ON ALARGE-SCALE LANDFILL

Abstract

In order to develop an effective environmental monitoring method for large-scale landfill sites, the authors carried out landfill gas monitoring, cover soil sampling and vegetation survey at the Laogang Landfill in Shanghai, China. The relationship between the degree of landfilled waste stability and the vegetation characteristics were tried to find out. Results indicated as follows;(1) after the landfill completion, vegetation began to grow where water content of cover soil was high, (2) the landfill gas concentration decreased where vegetation existed and permeability of air was high because of the effect of roots, and (3) the transition of the plant species was unique compared with normal land.
