摘　　要：分析了长春市绿园、宽城、朝阳、净月、二道等蔬菜种植区不同使用年限的日光温室土壤的微生物区系时空变化情况。结果表明,绿园、宽城、净月区种植10～15年的日光温室细菌、真菌和放线菌数量呈上升趋势,随着种植年限的延长有所下降;朝阳和二道区的真菌数量表现为先降后升;绿园区土壤放线菌数量随着种植年限的延长有缓慢减少的趋势。各区微生物区系比较,宽城区的细菌和放线菌数量最高,真菌数量居中;绿园区的细菌、真菌和放线菌数量均较低;朝阳区的真菌数量最高,细菌和放线菌居中;净月和二道区的细菌、真菌和放线菌数量介于其它区域之间。各个区域空间变化随着土壤层次的加深细菌和放线菌数量呈明显减少的趋势,真菌数量减少不明显。Changes of soil microbial communities in different rhizosphere soil of solar greenhouse in Lvyuan,Kuancheng,Chaoyang,Jingyue,Erdao districts of Changchun city for 20 years was investigated in this study.The population of bacteria,fungi and actinomycetes at Lvyuan,Kuancheng and Jingyue district increased gradually from 10 to 15 years after cultivation and then decreased as time increased.As well as,fungi population at Chaoyang and Erdao district decreased until middle of the cultivation periods and then increased. While, the population of actinomycete decreased gradually with time. The highest populations of bacteria, actinomycete and fungi were found in Kuancheng district, Kuancheng and Chaoyang individually. However, the lowest populations of bacteria, actinomycete and fungi were found at Lvyuan district. Average populations of microbial communities were found at left areas. At all area, the obvious decrement in the populations of bacteria and actinomycete were found with depth. However, there was no clear decrement was found in fungi population.
