江苏省海岸带北起锈针河口(北纬35°07＇),南抵启东咀(北纬31°46＇),岸线长1039.7公里。海涂土壤分布于海陆交界的潮间带,属滨海盐土土类。下分三个亚类:原始滨海盐土,面积为5,183,665亩;单甸滨海盐土,面积为656,540亩;沼泽滨海盐土,面积为297,960亩。三者总面积为6,138,165亩。其中已围未垦的面积为67.55万亩,堤外平均高潮线以上未围面积为124.75万亩。从统一规划、综合利用、因地制宜和生态平衡的要求出发,根据区内类似性、区间差异性的划区原则,把江苏省海涂土壤划分为四个开发利用区,即1.南通原始滨海盐土农、渔区;2.斗南草甸滨海盐土综合农业区;3.斗北沼泽滨海盐土苇、牧、渔区;4.淮北原始滨海盐土盐、渔区。
The coast of Jiangsu Province starts with rust pinhead (north latitude 35 ° 07 ’) and southward reaches Qidong Tsui (latitude 31 ° 46’) with a length of 1039.7 km. Tidal flat soil distribution at the junction of land and sea intertidal zone, is a coastal saline soil. It is divided into three sub-categories: the original coastal saline soil with an area of 5,183,665 mu; the single meadow coastal saline soil with an area of 656,540 mu; and marsh coastal salt soil with an area of 297,960 mu. The three total area of 6,138,165 acres. Among them, 67.55 mu of land has been encircled and not harvested, and 1.245 million mu has not been enclosed above the average height above the embankment. According to the requirements of unified planning, comprehensive utilization, local conditions and ecological balance, according to the principle of zoned area of similarities and interval differences in Jiangsu Province, the paper is divided into four development and utilization zones in Jiangsu Province, namely, 1. Nantong primitive coastal saline-soil agricultural , Fishing area; 2. Dounan meadows coastal saline soil comprehensive agricultural area; 3. Dabei marsh coastal salt soil reed, animal husbandry, fishing area; 4. Huaibei original coastal saline soil, fishing area.
