| 摘 要： | 利用河北省平原区朱家河小流域下博站1992～2012年土壤含水率实际观测资料，对土层0．0—1．8m深土壤含水率年际和年内变化规律及影响因素进行了分析：阐明了土壤含水率有逐步增大的趋势。年内土壤含水率汛期6-9月份最高，小麦成熟收割期及玉米成熟收获期土壤含水率最低，其他时段土壤含水率也维持在较高水平；指出了降水和农业灌溉是保持土壤含水率稳定的基本条件。

| Abstract: | Basis on soil moisture content of the actual observation data from 1992 to 2012 of Xiabo station in Zhujiahe River small basin on plain, the paper analyzed the interannual change rule and rule during the year and the influence factors of 0.0 - 1.8 m deep soil moisture content. Clarify the soil moisture content has a tendency to increase gradually, the soil moisture content of flood season from June to September is the highest in a year, the soil moisture content of harvest time of wheat mature and mature corn harvest is the lowest in a year, the soil moisture content of other time in a year is also maintained at a high level. Pointed out the rainfall and irrigation is the basic conditions to maintain the soil moisture content stability. |
