| 摘 要： | 利用2004年祁连山北坡五类天然草地生长季的土壤水分数据和同期的气象资料,以回归和相关分析的方法分析了气象因子对五类天然草地土壤水分动态变化的影响.结果表明:(1)土壤水分的动态主要受降水量及其季节分配的影响,并建立了降水量对土壤含水量的回归方程;(2)利用ASCE-PM模型计算了五类草地群落的潜在蒸散量,潜在蒸散量对...

| Abstract: | We conducted a field study by regression and correlation analysis to examine the relationships between soil moisture and meteorological factors for five kinds of grassland in the northern slopes of the Mountains Qilian;and soil moisture was collected from the study site along with synchronous meteorological data in 2004 for analysis.The results showed that(1) Dynamic change of soil moisture was determined by precipitation and its seasonal distribution,and regression equation between precipitation and soil m... |
