江苏沿江地区城市空间格局发展构想

江苏沿江地区包括拥有长江岸线的6个省辖市和15个县级市，土地面积和人口分别占全省的25.9 %和30.2 %，而GDP却占全省的48 %。沿江地区社会经济发展水平较高，但江南与江北区域差异明显，在所选择的8项社会经济城市发展指标中，除城镇密度外，其它7项指标江北均低于江南地区。沿江城市带可构建成宁通、宁苏、苏通三条城镇发展轴，宁仪、三江、泰扬三个城镇发展组团，其中宁通、宁苏二条沿江发展轴是城市带的中心轴线。各发展轴及城市组团的协调发展要以市场为纽带，以共同发展为宗旨，以可持续发展为目的，加大区域合作的力度。离岸港口城镇有港区功能较单一的发展模式及功能较全面的一种发展模式，规模较大的离岸城镇宜采取港区功能较全面的一种发展模式，小城镇则选择港区功能较单一的发展模式比较适合。

The along river region of Jiangsu includes 6 cities governed by the province and 15 cities governed by counties holding Yangtze River bank. The ground area and people along river region account for 25.9 %and 30.2 % for the two categories of the areas,but their GDP in total 48 per cent of the whole province.
