In the extremely arid hinterland of Taklamakan Desert, the artificial vegetation is irrigated by salt water with a salt content of 4~5g/L, thus the ecological environment is improved, soil forming process of aeolian sand soil is sped up, and the amount of soil inhabiting microorganisms and their activation are increased. The study results are as follows:① The amount of microporganisms in moving sand is a few and their activation is poor, which, however, are obviously increased after the vegetation is artificially planted and irrigated; ② Among the total amount of the soil-inhabiting microorganisms, bactoria are dominant, then actinomyces, and the amount of fungi is the least, and bacilli occupy a certain proportion in the bacteria; ③ The microbial physiological groups are also increased after the vegetation is artificially planted and irrigated; ④ Under the artificial vegetation, soil forming process has been started although it is still in an initial stage, and the biological sand-fixing effect is obvious.Read More
