Abstract:
The typical desert steppe in Yanchi,Ningxia was taken as example,selecting 4 kinds of common plant communities in the region,diversity and correlation of soil nutrient and soil microorganisms in different plant communities were analyzed.The results showed that the soil nutrient indexes had differences among different plant communities.The soil total nitrogen and alkaline nitrogen contents of Sophora alopecuroides community were relatively higher,the soil organic carbon content of Achnatherum splendens community was higher,the soil nutrient was generally poorer in Artemisia ordosica community,the soil available phosphorus content of Kalidium foliatum community was relatively higher.The quantities of 3 kinds of soil microorganisms in all 4 kinds of plant communities were different form each other in the same soil layer of different communities and in the different soil layers of the same community,but the quantities of soil microorganisms in 4 kinds of plant communities were bacteria>actinomycetes>fungi.There were differences of the correlations between soil nutrient and soil microorganisms in every index among 4 kinds of plant communities.The relations of various indexes of S.alopecuroides community were the most close,that of A.splendens community took the second place,that of A.ordosica and K.foliatum community were more complicated.Thus,according to the characteristics of soil nutrient and soil microorganisms of different plant communities,and provided a certain reference basis for desert grassland restoration and management.
