Experimental Study on Soil Reconstruction and Vegetation Restoration in Bayan Obo Mining Area
In order to promote the utilization of solid waste resources and the restoration of mine eco-logical environment in Bayan Obo mining area,aiming at the problems of special climatic conditions,cold,drought,windy and lack of topsoil treatment in the mining area,the soil reconstruction test is carried out by using the tailings of the mining area and the fermented sludge of the sewage treatment plant as raw materi-als,and the characteristics of the reconstructed soil with different ratios and the growth of the plants are ex-plored.The test results show that the reconstructed soil can be prepared by using the tailings of the mining ar-ea and the fermented sludge of the sewage treatment plant.With the increase of the sludge content,the soil bulk density of the reconstructed soil is effectively reduced,the organic matter content is significantly in-creased,and the content of N,P and other nutrients in the soil is increased,which is conducive to the growth of plants and the restoration of vegetation.
