| 摘 要： | 根据1999年竣工的南四湖清障工程实施前后的水文观测资料,从湖区水面比降、洪水落平时间等要素的变化,进行了湖区行洪分析。通过分析发现:工程的实施,降低了卡口段的水位,减小了工程位置以下的湖区水面比降,缩短了湖区行洪时间,加快了洪水宣泄,使入湖河道洪水尽快下泄,提高了湖区行洪能力,分析成果对南四湖防洪调度以及进一步做好湖内清障工程,具有重要的参考价值。

| Abstract: | According to observed data of the lake area water suface slope and the time of flood rise changes before and after bond around clear project completed from in 1999 the Nansi Lake's hydrology was analyzed It is known from analysis that after the execution of engineering,the water level of bayonet segment was reduced,the surface slop below the engineering site decreased,the lake flood time shortened,the flood dischange expedited,the water course flood dischange quickly made,and the ability of flood in take area improved.The analyzed results have the important reference value to Nansi lake's flood control scheduling and cleaning barrier project. |

| Keywords: | Nansi Lake lake area surface slop the time of flood fall and rise |
