东北草原八种群落类型的现状及土壤环境的初步研究

A initial study on 8 communities and its soil environment in the Leymus chinensis grassland of northeastern China

通过对东北羊草草原 8种群落类型的地上植被 ,土壤理化因素 ,土壤微生物的初步调查 ,取得的数据用模糊分析的方法进行比较研究 ,结果表明 :虎尾草群落类型和杂草群落类型与羊草群落最相似 ,碱茅群落类型和碱蓬群落类型的相似程度最小 ,隐子草群落类型 ,拂子茅群落类型和芦苇群落类型的相似程度居中。在未来的群落演替过程中 。

The vegetation on the ground,physical and chemical factors in soil,microorganism were initialy investigated in 8 plant communities of the grassland of northeastern China,and analysed in blurred mathematics method.The results indicated: Chloris virgata community and weeds community are best similar with the Leymus chinensis community,and Puccinellia tenuiflora community and Sueda glauca community are less similar with L.Chinensis community,the similarity of Cleistogenes sqarossa community, Clamagrostis epigeios community and Phragmites communis community are mediate with L. chinensis community.
