利用时间序列理论分析了降水动态和土壤含水量动态的相关关系。研究表明．降水序列为不相关序列，而各层土壤含水且序列同为自相关序列。相关时间里为2至7个行后时间里。降水序列和30、60、Kkm含水且及全剖面使水且（bel＆bxl）的协相关图呈现一定的周扭住，用用分别为3．5、4、5和4个踢后时间距（If后时间医为5天）．表明降水的动态变化在相同相应的话后时间区后分别在30、60、K）all深度含水且及全剖面储水量的动态图上得到重现。
Using time series theory, the correlation between precipitation dynamics and soil moisture content was analyzed. research shows. Precipitation sequence is irrelevant sequence, while soil layers in each layer have the same sequence of autocorrelation. The relevant time is 2 to 7 lines after the time. Precipitation series and 30, 60, Kkm water and total cross-sections of water and (cob / bxl) coherence showed a twist around the week, with respectively 3.5, 4, 5 and 4 kicking time interval After the time for medical 5 days). It shows that the dynamic changes of precipitation are reconstructed on the dynamic maps of 30, 60, K) all deep water and total water storage after the same corresponding post-time zone respectively.
