Abstract: Choosing soil of campus green space such as pure forest, meadow, and bush fallow as researching materials in the Neijiang Teachers College, and the soil from the neighborhood farmland as reference object, soil anti-erodibility indices including volume-weight, the mechanical composition, the drying sieve aggregate, disintegration rate, water stability index were measured and analyzed. The results showed that there exists significant difference in the soil mechanical of different Campus green space. The order of physical clay content was as follows: bush fallow > pure forest > meadow >farmlands. The order of sand grain content was: meadow < bush fallow < farmlands < pure forest. There was significant difference among the drying sieve aggregate composition of different land model. The order of soil collapse rate was: bush fallow > pure forest > meadow >farmlands. Furthermore, the soil collapse rate of bush fallow, pure forest, and meadow were increasing in vertical direction, on the contrary, farmlands were in decreasing order. The order of water stability index was: bush fallow > pure forest > meadow >farmlands. On the other hand, the water stability index of pure farmlands was increasing in vertical direction; yet, the other 3 models were decreasing. According to the above analysis, the conclusion was that the order of soil anti-erodibility of campus green space was: bush fallow > pure forest > meadow >farmlands. Based on the results, advances some Suggestions on the campus soil protection were put forth in hope of providing some reference for the campus greening.
