Analyze the hydrologic characteristics of tao river basin, the influence on the hydrology progress imposed by physiographic factors, and variation of the relationship between rainfall and runoff.
分析研讨了洮河流域的流域特征、主要自然地理要素对水文的影响，以及降雨径流要素的变化规律。

The results shows, the relationship between individual rainfallrunoff depth and it's sediment yield is very close.
结果表明，次降雨径流深与其对应所产生的侵蚀量关系非常密切；
3
Surface crust could easily take place on bare land, so its runoff-yielding time primarily depended on rainfall intensity, and their relationship might be described by a linear function.
