The probability of annualrunoff for high, normal, and low flow years due to the change of meanannualrunoff was studied.
并研究了仅由均值变化引起的这两个流域丰水、平水及枯水年出现的概率变化。

For forest watershed and shrub watershed, the annualmeanrunoff coefficient was affected by meanannual precipitation, mean annual evapotranspiration and mean slope grade.
对于森林流域和灌木流域，其多年平均径流系数主要受多年平均降水量、多年平均蒸散量和平均坡度共同影响；

The further study shows that summer air temperature and precipitation have much correlation with annualmean of Manas runoff.
