摘要:
通过实地调查和试验分析，研究了秦岭北坡杨树人工林、刺槐人工林、油松人工林和荒坡等4种植被类型的土壤养分状况和微生物特征。结果表明：①4种植被类型土壤养分存在差异，杨树人工林与刺槐人工林土壤养分含量均较高，油松人工林养分含量相对较低，荒坡最低。②4种植被类型中，土壤微生物数量以细菌最多，其次为放线菌，真菌最少。除真菌数量外，细菌、放线菌和微生物总量依次为杨树人工林最多，刺槐人工林较多，再次为油松人工林，荒坡最少。③4种植被类型土壤养分含量与土壤微生物数量基本均随土层加深表现为减少趋势，表明土壤微生物数量与土壤养分含量有关。④4种植被类型中土壤养分含量和土壤微生物数量比较研究表明，人工林能够较好地改善土壤状况，阔叶林改善土壤状况较针叶林更为有效。
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.
