黄河下游两岸,由于历史上曾经多次决口和历年不断地培堤挖土,遗留下许多大小不等的积水坑,沿堤形成了一片低洼易涝地带。它不仅对发展农业生产不利,也十分严重地威胁着堤防的安全。近十年来,为了改变这种情况,下游人民在党的领导下,利用已建成的虹吸管和涵闸工程,进行了大量的放淤工作。做得较好的地区,既加固了堤防,也已初步改良了涝 Since both sides of the lower reaches of the Yellow River have repeatedly set off many dikes and dug dike continuously over the years, many water puddles of various sizes have been left behind, forming a low-lying flood-prone strip along the dike.
