摘要
在分析黄河中游径流情势变化趋势的基础上，建立了适用于该区间的月水量平衡模型，并利用９个代表流域的资料进行检验，模型结构简单，具有较高的模拟精度。用所建模型分析１９７０年后人类活动对径流的影响，取得了比较可靠的结果。
Abstract The properties of the change of runoff regime at nine basins in the Yellow River are analyzed. A monthly water balance model was developed and used to analyze the change of runoff in the basins. It was found that an obvious decrease in the runoff since 1970. The effects of human activities on the runoff regime in the basins are analyzed quantitatively.
