| 摘 要： | 本文采用水文时间序列模型ｘｔ＝Ｔｔ＋Ｐｔ＋Ｒｔ模拟实测水文过程．分析结果表明，人类活动 对趋势项Ｔｔ影响很大．而周期项Ｐｔ和随机项Ｒｔ则几乎没什么影响．在此基础上，根据Ｔｔ的变化 规律，作者对环境影响下的水文过程进行预测．

| Abstract: | In this study, time series model, Xt = Tt + Pt + Rt, is used to simulate the ob- served hydrologic process. The results show that human activities have a great influence on trend component Tt, but nothing on periodic component Pt and random component Rt . Based on the characteristics or Tt, this model is used to predict some hydrologic processes under the environmental changes. |
