中文摘要：

本文通过对海河流域的38个子流域及内陆河流域的7个子流域的逐年降水、径流及实际蒸散发和蒸发能力的分析．证明了基于Budyko假设的流域水热耦合平衡关系在海河及西北内陆河流域是成立的。根据各子流域的长期水量平衡结果，本文验证了水热耦合平衡模型中的唯一参数综合反映流域的下垫面条件且具有显著的区域分布规律，与此同时，本文还在海河流域及内陆河流域对根据流域平均坡度（tanB），相对土壤最大蓄水能力（Smax/^→ E0）和相对土壤入渗能力（Ks/^→ir）估算模型参数^~ω的经验公式进行了验证．计算结果较好。

英文摘要：

Through the analysis of annual water balance, based on Budyko Hypothesis, a coupled water-energy balance relationship has been established for the Haihe River basin and inland fiver basins. The unique parameter in the coupled water-energy balance model shows a signif- icant regional pattern. And it has been proved that this model parameter represents the land surface conditions of the studied catchments. At the same time, the present study has proved the empirical relationship （equation 3） for estimating the model parameter from average slope, the relative maximum soil water holding capacity and the relative infiltration capacity to be of validity in Haihe River basin and inland fiver basins.
