摘要:

2000年8月29日下午, 受乌拉尔山低涡分裂短波东移的影响, 新疆昌吉州呼图壁县南部天山北坡山区位于86°15'00"~86°42'32" E, 43°41'50"~44°08'08" N的范围内形成局部强对流降水天气, 在军塘湖河流域与临近石膏沟流域发生特大暴雨洪水, 造成了流域内人民生命财产巨大损失. 水文部门于当年8月31日开展了对军塘湖河流域的洪水调查, 通过实地调查和流域降雨量分析, 以及采用比降面积法计算, 确定军塘湖河"8·29"特大洪水洪峰流量为781 m3·s-1, 其中, 石膏沟流域的东支沟洪峰模数达16.4 m3·s-1·km-2, 是新疆截至目前为止出现的最大洪峰模数. 调查结果和计算认定军塘湖河流域"8·29"洪水属于特大洪水.

Abstract:

On August 29, 2000 in the afternoon, influenced by low vortex division short wave eastward movement of Ural Mountain, Hutubi County Mountain Area Changji Prefecture South located at east longitude 86°15'00" to 86°42'32", and the north latitude 43°41'50" to 44°08'08". a local strong convection precipitation weather grew, causing a torrential rainstorm and flood in Juntanghu River basin and drawing near gypsum Ditch lake, which destroyed people's life and property. In order to master the levels of the flood, the department of hydrology investigated the flood in Juntanghu River basin on August 31 that year. Basing on a research and analysis on the field and rainfall, the peak flow of the huge flood is 781 m3·s-1, which calculated by slop-area method. The modulus of flood peak reached to 16.4 m3·s-1·km-2 in the east branch in the Shigaogou basin. The modulus is the biggest one in Xinjiang so far."August 29" flood in Juntanghu River basin was a catastrophic flood.

Key words: Juntanghu River basin, catastrophic flood, modulus of flood peak, Xinjiang
