中文摘要:
      基于西昌旱地土壤湿度资料,以备选因子是否加入上一次实测值为前提,对土壤湿度和气象因子进行逐步回归分析,结 果表明,在所提供的备选因子中,降水量、蒸发量、无雨日数与土壤湿度相关关系更密切;加入上一次实测值作为因子,所生成 的回归方程拟合精度和预测精度均明显提高。
英文摘要:
      The stepwise regression analysis of soil moisture and meteorological factors was carried out based on the soil moisture data of Xichang dry land and whether the last measured values was added to the selected factors. The results showed that the precipitation, evaporation and rainless days of the selected factors were more closely related to soil moisture, and after adding the last measured values as a factor, the fitting accuracy and prediction accuracy of the regression equation are obviously improved.
