        河道整治分类
        Classification of river regulation
        为防 洪、航运、供水、排水及河岸洲滩的合理利用,按河道演变的规律,因势利导,调整、稳定河道主流位置,以改善水流、泥沙运动和河床冲淤部位的工程措施。河道整治分两大类:①山区河道整治。主要有渠化航道、炸礁、除障、改善流态与局部疏浚等。②平原河道整治(含河口段)。主要有控制和调整河势、裁弯取直、河道展宽及疏浚等。中国有4000年前禹疏九河,导流入海的传说。明代的潘季驯治理黄河颇有成效,他还著有《河防一览》,其中“以河治河,束水攻沙”的理论,具有创见性和科学性,流传久远。随着近代水力学、河流动力学、河道泥沙工程学的进步,河工模型试验的发展及工程材料的改进,河道整治发展到一个新的阶段。
        In order to prevent flood, navigation, water supply, drainage and rational utilization of riverbank and beach, according to the law of river course evolution, adjust and stabilize the position of main stream according to the situation, so as to improve the engineering measures of flow, sediment movement and the location of riverbed scouring and silting. River regulation can be divided into two categories: 1. River regulation in mountainous areas. There are mainly channelized waterways, reef blasting, barrier removal, improvement of flow pattern and local dredging, etc. (2) Plain river regulation (including estuary section). It mainly includes controlling and adjusting River regime, cutting bends and straightening, river channel widening and dredging, etc. The legend of Yushu Jiuhe River flowing into the sea 4,000 years ago in China. Pan Jixun of the Ming Dynasty had made great achievements in harnessing the Yellow River. He also wrote A Glimpse of River Defense, in which the theory of "harnessing rivers with water and attacking sand with water" was innovative and scientific and had a long history. With the progress of modern hydraulics, river dynamics and river sediment engineering, the development of river model tests and the improvement of Engineering materials, river regulation has developed to a new stage.
