通榆河在我省苏北东部地区,规划南起南通市接通长江,北至连云港市、赣榆县,全长360公里,是基本平行于京杭大运河的又一条苏北运河。该河从1958年起就进行了规划,并实施了部分工程,但未全线接通,不能发挥南北水运干线和送水的作用。最近省委、省政府决定进行综合开发通榆河的可行性研究,这是加快发展苏北的重要决策。解放以来,大规模的治淮建设和农田水利建设,极大地改变了苏北生产条件,农业面貌发生了根本变化,形成了里下河,徐淮两个新的商品粮基地,省内南粮北调的问题已根本解决。但是,就经济发展水平看,苏北与苏南还是有较大的差别。南通、盐城、淮阴、连云港四市总面积3万平方公里,人口1800余万,均占全省三分之一左右,根据1983年资料,人均产值950元;人均财政收入65元,都比全省平均值1350元和125元低很多。而苏夕常三 Tongyu River in eastern Jiangsu province in the eastern part of our province, planning Nantong City, connecting the Yangtze River from the north to Lianyungang City, Ganyu County, a total length of 360 kilometers, is basically parallel to the Beijing-Hangzhou Grand Canal is another Subei canal. Since 1958, the river has been planned and some projects have been carried out. However, the river is not connected to the whole line and can not play the role of the South-North Water Transport Trunk and the water supply. Recently, the provincial government decided to conduct a feasibility study on the comprehensive development of the Tongyu River. This is an important decision for accelerating the development of North Jiangsu. Since the liberation, the large-scale construction of water control and harnessing Huaihe River has greatly changed the production conditions in northern Jiangsu. The agricultural landscape has undergone fundamental changes, forming two new commodity grain bases in the Lixiahe and Xuhuai areas. The problem of adjustment has been basically solved. However, judging from the level of economic development, there is still a big difference between northern Jiangsu and southern Jiangsu. Nantong, Yancheng, Huaiyin, Lianyungang four cities a total area of ​​30,000 square kilometers, population 1800 million, accounting for about one-third of the province, according to 1983 data, the per capita output value 950 yuan; per capita financial income 65 yuan, than the whole The provincial average of 1350 yuan and 125 yuan a lot lower.
