Abstract Based on experiments,the content of soil nutrients in mine areas wastelands were analyzed.The results show that: the content of soil nutrient of planted land is more higher than that of the wasteland and the natural restorated land,it shows that the soil nutrient of wastelands were clearly improved by plantation;except the phosphor content,the other soil nutrients are more less than that of the forest stands;the best plant with improving effect is the Salix matsudana,the soil organic matter content of which is 37.28 g/kg,2.6 times of the residue.The Hippophae rhamnoides L.plantation can increase the content of the soil nutrient in the cinder pile of power house,the soil organic matter content of which is 48.25 g/kg;The content of the soil nutrient were rise fast by plantation in flat coal waste rock pile and close to the forest stands,the soil organic matter content of mixed planting Larix gmelinii Rupr. and Ulmus pumila L.are 193.42 and 151.46 g/kg respectively,which is 8.9 and 7 times of that under natural recovery conditions;It was suggested that the dominant species(Pinaceae for example) should be planted to increase the speed of the succession.
