【摘要】 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。更多还原

【Abstract】 The coastland of Jiangsu Province lies from the mouth of the Xiuzhen River (35°07’N) in the north to Qidongzui (31°46’N) in the south, 1039.7 kilometers in length, The beach soils spread over the intertidal zone between the sea and the land. They can be classified into three subgroups: primeval seashore saline soil, 5,183,665mu; meadow seashore saline soil, 656,540mu; marsh seashore saline soil, 297,960mu; totalling 6,138,165mu. Among them 675,500mu have been dammed up but not yet cultivated, and 1,247,500mu above the average high-tide line have not yet been enclosed in dams. With the main of unified planning, comprehensive utilization, suiting the local conditions and maintaining ecological balance, according to the ecological conditions and the division principles of "similarity within the division" and "difference be tween divisions", the beach soils in Jiangsu Province are divided into four regions for reclamation, i.e.1) agriculture-fishery region of Nantong primeval seashore saline soil; 2)integrative agricultural region of Dounan meadow seashore saline soil; 3) Reed-livestock-fishery region of Doubei marsh seashore saline soil; 4) Salt-fishery region of Huaibei primeval seashore saline soil.更多还原
