The relationship between edaphon amount and distributing type of vegetation and soil in desert grassland in Ningxia. The result showed that:(1) the order of bacteria amount was light loam＞mid loam＞sand loam＞close sand;(2) distribution of actinomycete was close sand＞sand loam＞light loam ＞mid loam; (3) the distribution of fungi amount was mid loam＞light loam＞sand loam＞close sand; (4) the amount of edaphon varied with vegetation type while bacteria amount came to head in vegetation type ④, actinomycete in ① and fungi in ②; (5) vegetation in mid loam and light loam grew well and its value of 4-degree measurements was high accordingly but lower in close sand.
