针对平原城市自排区的排涝特点，通过分析几种排涝计算方法的原理及计算结果，提出了适用于平原城市自排区排涝模数计算的一维非恒定流法。以安徽省宿州市主城区为例，分别采用平均排除法、割平头法和非恒定流法计算其排涝模数。结果表明：非恒定流法更适用于平原自排区排涝模数的计算，为城市排涝提供了依据。

Aiming to the characteristics of drainage in the plain city ,the paper put forward 1-D unsteady flow method by analyzing the principles and results of other methods .Taking the main city of Suzhou in Anhui province for example ,the paper used three methods including the average elimination , cutting flat-head law and unsteady flow method to calculate the drainage modulus .The result indicated that the un-steady flow method is more applicable in calculation of drainage modules of plain city and can provide a basis for urban waterlogging .
