摘要: 为应对校园内每逢下雨便会产生的积水问题,以宝鸡文理学院东校区为例,用称重法测定不同植被条件下0~30 cm平均土壤含水率的变化,并分析不同绿地类型的分布特征,用SPSS 20.0等相关软件对测量数据进行统计分析。结果表明,平均土壤含水率表层(0~10 cm)>亚表层(10~20 cm)>20~30 cm土层;乔木林地雨后平均土壤含水率表现为银杏(Ginkgo biloba L.)>雪松[Cedrus deodara (Roxb.) G. Don]>樱花树(Cerasus yedoensis)>龙爪槐(Sophora japonica)>柿子树(Diospyro skaki Thunb)>红叶李(Prunus cerasifera);灌草地雨后平均土壤含水率表现为红叶石楠(Photinia×fraseri Dress)>复层植被>草坪>金竹(Phyllostachys sulphurea)>大叶黄杨(Euonymus japonicus Thunb)。疏林较密林更容易吸收降水量,乔木林地较灌草地含有高水分值,而草地较稠密灌木林地来说更易减少降水的流失。

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
