近几年来,上海郊区河道普遍淤浅,据调查全市县、乡、村三级淤浅总土方达7000万立方米,严重影响了农业的排涝、灌溉和水运,一些地方落潮时河底朝天,电灌站在干旱季节甚至抽不上水,抗灾能力下降。为此1985年市、县、乡制订了疏河的三年规划,大声疾呼:动员群众开展疏河。三年已经过去,每年完成了近千万立方米疏河土方量,比84年增长了60％以上,但是三年规划要求每年疏河2000万立方米,远末完成三年规划要求。按照这个速度还要化十二年时间才能完成疏河任务。
In recent years, the suburbs of Shanghai generally have shallow silt up the river. According to the survey, 70 million cubic meters of silt mined at the county, township and village levels have seriously affected the drainage, irrigation and water transport in agriculture. In some places, Electric pumping station in the dry season and even pumping water, resilience decreased. To this end, in 1985, the city, county and township formulated the three-year plan for the Shuhe River to shout aloud: to mobilize the masses to carry out the flood control. Over the past three years, nearly 10 million cubic meters of earthwork have been completed every year, an increase of more than 60% over the past 84 years. However, the three-year plan calls for 20 million cubic meters of river dredging each year and fulfilling the three-year planning requirement. In accordance with this speed even further twelve years to complete the tasks of the river.
