| 摘 要： | 为了给新疆石河子垦区农业可持续发展、合理开展农业生产和气候资源利用等提供气候依据,笔者统计分析了新疆石河子国家一级农试站1996—2015年20年来0~50 cm月平均土壤湿度、年平均土壤湿度变化特征及与其他气象因子的相关性。结果表明:0~50 cm年平均土壤湿度总体呈偏湿趋势;石河子国家一级农试站0~10 cm月平均土壤湿度3月和4月湿度最大,6月、7月和8月湿度最小,随着土壤深度的增加,土壤湿度各月相差不大;0~10 cm年平均土壤湿度变化存在着准13年的年代际周期和准5年的年际周期,40~50 cm年平均土壤湿度存在着准10年的年代际周期和准5年的年际周期;0~10 cm和10~20 cm年均土壤湿度存在突变特征;0~50 cm年平均土壤湿度与年降水量、年蒸发量和年0 cm地温这些气象因子最为敏感。

| Abstract: | To provide climatic information for agricultural sustainable development, and reasonable utilization of agricultural and climate resources in Shihezi, Xinajing, the authors statistically analyzed 0-50 cm monthly average soil moisture, annual average soil moisture and its correlation with other meteorological factors in Xinjiang national agriculture test station from 1996 to 2015. The results showed that: 0-50 cm monthly average soil moisture overall showed a trend of wet; 0-10 cm monthly average soil moisture in March and April were the largest, the smallest humidity was found in June, July and August, with the increase of soil depth, soil moisture had little difference between each month; the change of 0-10 cm annual average soil moisture had a decadal cycle of 13 years and an annual cycle of 5 years, the change of 40-50 cm annual average soil moisture had a decadal cycle of 10 years and an annual cycle of 5 years; the characteristic of 0-10 cm and 10-20 cm annual average soil moisture had mutations; 0-50 cm annual average soil moisture was most sensitive to the meteorological factors of annual precipitation, annual evaporation and annual 0 cm ground temperature. |
