摘　　要：影响小流域最大排涝量精度的因素有很多,一方面,由于测量数据的误差,也就是洪水资料的可靠性,代表性和一致性,这些因素会导致统计参数的偏差,从而影响设计洪水的精度;另一方面,目前国内推求小流域最大排水量的方法有很多,相互之间也存在差异。本文以潞市水闸和丰山水闸为研究区,通过排涝计算,比较经验公式法以及平均排除法求得的最大排涝流量与设计值之间的误差。There are a lot of factors influencing the accuracy of the maximum drainage capacity in small watershed. On one hand, because of the error of the data, which is flood data including reliability, representative and consistency, these factors could lead to deviation of statistical parameters, which and affect the precision of design flood. On the other hand, there were a lot of the current domestic new methods to determine the maximum displacement of small watershed has a lotin our country. They were different from there are also differences between each other. Taking the article based on Lushi and Fengshan sluice as the research area, this article compared the difference between the degined maximum drainage and calculated value through empirical formula method and average method.
