Abstract: In order to cope with the problem of water accumulation in every rain on campus, taking the eastern campus of Baoji University of Arts and Sciences as an example, the average soil moisture content of 0~30 cm under different vegetation conditions is measured by weighing method, and the distribution characteristics of different green space types are analyzed. SPSS 20.0 and other relevant software are used for statistical analysis of the measured data. The results show that the average soil moisture content shows surface layer（0~10 cm）>subsurface layer（10~20 cm）> 20~30 cm soil layer; The average soil moisture content of trees forest after rain Ginkgo biloba L.>Cedrus deodara （Roxb.） G. Don>Cerasus yedoensis>Sophora japonica>Diospyro skaki Thunb>Prunus cerasifera; The average soil moisture content of shrub grass after rain shows Photinia×fraseri Dress>stratified vegetation>lawn>Phyllostachys sulphurea>Euonymus japonicus Thunb. Sparse forest is easier to absorb precipitation than dense forest, tree forest contains higher water value than irrigated land, and grassland is easier to reduce precipitation loss than dense shrub forest.

Key words: sponge campus, average soil moisture content, soil depth, campus greenland
