摘要
在玉林市远郊-近郊-市区等不同城市化水平区内选取林地、草地和路边土几种不同利用方式下的土壤,对土壤中微生物状况进行初步分析.结果显示:(1)从微生物的情况来看,从远郊到近郊再到市区,随着城市化水平的提高,微生物总量表现为远郊明显高于市区和近郊,近郊和市区的变化不明显.(2)从不同区域相同利用方式来看,林地、草地、路边土中细菌、放线菌、真菌的变化比较明显.(3)从相同区域不同利用方式来看,市区细菌、放线菌变化比较明显,真菌变化不明显,近郊真菌、放线菌变化比较明显,细菌变化不明显,远郊细菌、放线菌和真菌变化比较明显.
Top soil were sampled from woodland ,meadow and roadside separately in exurb, outskirts and the city zone in Yulin city and microorganism status in different samples was analyzed. The result shows that (1) the total amount of microorganisms in exurb is obviously higher than those in outskirts and city zone with the improvement of urbanization level. The change of microorganism amount in outskirts and city zone is not obvious, (2) In the view of the same using pattern of different regions, the amount of bacteria, actinomycetes and fungi from woodland,meadow and roadside change obviously.(3) In the view of the same regions of different using pattern, The amount of bactera and actinomycetes in city zone changes obviously, but the fungi does not. The amount of fungi and actinomycetes in outskirts changes obviously,but the bacteria does not. The amount of bacteria, actinomycetes and fungi in exurb changes obviously.
