摘要
为了研究不同土地利用类型下土壤水分的变化情况,以渭南市临渭区2010—2014年的年降水量作为研究数据,根据陕西省渭南市临渭区的玉米地、苹果园、麦地、草地、蔬菜地、林地6种土地类型的土壤样品,总体上运用了对比分析法和Bonsal边缘分布函数法。结果表明：在临渭区的小范围内,蔬菜地的土壤水分含量在6种土地利用类型中是最高的,苹果园的土壤水含量是最小的;降水的季节变化与耕作层土壤水分含量的变化是成正相关的;降水级别的悬殊对土壤湿度的作用是正向的,而且不同的降水等级之间,土壤湿度的差异是非常明显的;在临渭区0~100cm各层土壤中,0~30cm的土壤湿度与降水量的关系最好。
In order to study the change of soil moisture under different land use types, taking Linwei annual rainfall of 2010-2014 as the research data, according to the corn, apple orchards, field, grass, vegetables, forestland six land types of soil samples, using comparative analysis and overall Bonsai edge distribution function method. Results show that in a small scale, soil moisture content in the land of vegetables is the highest in six kinds of land use type, apple orchard soil water content is the smallest ; Magnetism of seasonal change of precipitation is positively related to the change of soil moisture content ; Precipitation level difference is positive effect on soil moisture, and between differ- ent level of precipitation, soil moisture difference was very obvious;In the soil of 0 - 100 cm, the relationship be- tween soil moisture and precipitation in 0 - 30cm is the best.
