Abstract:: Through field investigation and experiment analysis,the soil nutrient status and microbiological properties of Populus cathayana plantation,Robinia pseudoacacia plantation,Pinus tabulaeformis plantation and wasteland were studied.The main results had abtained.The soil nutrient was significantly different in four vegetation types.The soil nutrient of Populus cathayana plantation and Robinia pseudoacacia plantation were the highest.The soil nutrient of Pinus tabulaeformis plantation is less and wasteland is the least.The quantity of soil bacteria is most,the quantity of soil actinomycetes is less,and the quantity of soil fungi is the least.Except of the quantity of soil fungi,the quantity of soil bacteria,actinomycetes and amount of microorganism of Populus cathayana plantation is the most,the quantity of soil bacteria,actinomycetes and amount of microorganism of Robinia pseudoacacia plantation is more,Pinus tabulaeformis plantation is less and wasteland is the least.The soil nutrient and microbiological quantity of four vegetation types deceased with soil depth increase,indicating that microbiological quantity was closely related to soil nutrient.The result of soil nutrient and microbiological quantity indicated that plantation was able to improve soil quality,and the improvement effection of broad-leaved is better than that of coniferous forest.
