长春市朝阳区绿地土壤微生物变化研究

Study on Green Land Soil Microbial Change of Chaoyang District Changchun City

对长春市朝阳区不同功能绿地下不同植被类型土壤的基本理化状况及微生物含量变化进行了分析研究。结果表明:不同功能区土壤微生物含量随有机质、含水量变化表现为公园绿地>广场绿地>学校绿地>居住区绿地;不同植被类型下土壤微生物含量变化表现为乔灌>草灌>草地;细菌变化较大,占有较大比例,而放线菌、真菌变化不明显。

The different vegetation types of soil physical condition, chemical conditions and basic variation content of microbial of the different function of green land in Chaoyang district Changchun city were analyzed. The results showed that microbes of different function areas changed with the organic content,water content were changed. The performance for water content changed of the park 〉 square〉 school〉 residential area. Under different vegetation types of soil, microbial content change showed arbors 〉 shrub 〉 grass. Bacteria content changed a lot and took a large proportion, actinomycetes and fungi did not change significantly.
