淳安县位于浙西山区,地形地质复杂,源短坡陡,洪枯变幅大,洪水位高,水土流失严重。大部分城镇、村庄、良田和各种基础设施成点片状分布在溪沟两岸。随着保护对象的增多,洪灾造成的损失也逐年增大。该文结合淳安县几年来河道整治规划方面的经验,对河道整治规划设计的一些问题进行了探讨。 Chun’an County is located in the western mountainous area of ​​Zhejiang Province. Its terrain and geology are complex with steep source and short slope, large flood amplitude, high flood level and serious soil erosion. Most towns, villages, fertile fields and various infrastructures are distributed in flake distribution over both banks of the Xikou. With the increase of protection objects, the losses caused by floods also increase year by year. Combined with the experience of Chun’an County in river regulation in recent years, some problems of river regulation and design are discussed.
