近年来,各地方河道流域的洪涝灾害频繁发生,而导致洪涝灾害发生的不仅仅是气候原因,最主要的原因是大多河道的主河槽变窄、河床被淤泥抬高阻塞、河滩大部分面积被附近村庄耕种农作物、河道建筑物及两岸堤防失修所造成的,因此,对河道流域的综合整治势在必行。 In recent years, floods and floods in various river basins have been frequent occurrences. The most important reason for causing floods and disasters is not only the climatic reasons, but also the narrowing of the main channel in most of the river courses, Due to the cultivation of crops in nearby villages, river structures and disrepair of embankments across the Taiwan Strait, comprehensive regulation of river basins is imperative.
