| 摘 要： | 利用2004-2007年每天的土壤水分监测数据,研究了重庆铜梁地区土壤水分的动态变化,并对生长季土壤水分的变化进行了动态模拟。结果表明,监测年内各层土壤水分无论在枯水年还是平水年均有显著差异,平水年土壤水分含量和变异系数均高于枯水年;土壤水分的季节变化可分为稳定期、消耗期、波动期。用Laio模型推导出的土壤水分峰度和变幅与观测结果基本一致。

| Abstract: | The daily monitoring data on soil water in 2004-2007 were taken to study the dynamic change of soil water in Tongliang region of Chongqing,and the change of soil water in growth stage was dynamically simulated.The results showed that the differences of water content in each soil layer in dry year and normal year were all obvious in monitoring year.The soil water content and its variation coefficient in normal year were all higher than those in dry year.The seasonal variation of soil water could be divided i... |
