摘要
分析了乌鲁木齐市以小流域为单元,在复杂的地形、地貌和不同的气候背景下,进行临界雨量的分区,并相应提出在阿拉沟流域取点与现有的气象站点构成5个代表点,运用泰森多边形法进行小流域分区,可达到科学、合理的效果,进而为山洪灾害防治规划研究提供了可靠的技术参数。
In the background of complex terrain and different climates in Urumqi,the critical rainfall distribution of mountain flood was found. In the process of research,Taisen polygon method is used. This method makes the results more reasonable and accurate,which can be used as reference for further study on prevention and control regionalization of mountain flood disasters.
