清水河是和硕县水资源利用的主要河流,亦为和硕县洪灾主要根源,其洪水灾害造成的损失已成和硕县洪灾损失的主体。由于流域内具有特殊的地形条件和气候条件,加上防洪能力不足,排洪出路不畅,使得洪水灾害频繁发生,水土流失日趋严重。特别是春洪,融雪加降雨,可形成较大的峰和量,造成房倒屋塌、人畜伤亡、水利工程被毁、土地被毁、交通、通讯、电力中断等。汛期破坏性极大的洪峰不能被调控削减,对平原灌区形成频繁的、大范围的洪水灾害;对流域区经济建设、城市建设及人民生命财产安全构成极大威胁。通过对清水河流域洪水特性的分析研究,对有效地做好该流域的防洪减灾工作,发展区域经济最有重要意义。
Qingshui River is the main river for water resources utilization in Heshu County. It is also the main source of flood in Heshuo County. The loss caused by flood disaster has become the main body of flood damage in Heshuo County. Due to the special terrain conditions and climatic conditions in the basin, coupled with insufficient flood control capability and poor flood discharge route, flood disasters frequently occur and soil and water loss become increasingly serious. In particular, spring floods, snowmelt and rainfall may form larger peaks and quantities, resulting in housing collapses, human and animal deaths, water conservancy projects, land destruction, traffic, communications and power interruptions. Flood peak destructive flood peak can not be controlled and reduced, the formation of frequent floods in the plain, a wide range of floods; basin economic construction, urban construction and the safety of people’s lives and property pose a great threat. Through the analysis of the flood characteristics of the Qingshui River Basin, it is of great significance to effectively carry out the flood control and disaster reduction in this basin and to develop the regional economy.
