苏北盐城地区的盐土,主要分布在串场河以东,拼茶运河以北,灌河以南,约有12,500平方公里,共有耕地686.6万亩。包括滨海、射阳、大丰三县全部,东台、盐城、阜宁三县串场河以东的部分地区。这一地区,是由江、淮、黄河冲积物受海水顶托而沉积的海滩平原。地势平坦,微向海面倾斜,海拔高度(以废黄河口零点为基点)在2—5米之间,在拼茶运河及废黄河床附近较高,为4—6米;以射阳河北部和滨海县东部地形较低,为1.5米左右,沿射阳河两岸局部地区在1米左右。气候属东南亚季风区,大致以射阳河为界,南部为海洋性气候,北部因接近华北大平原,兼受大陆性气候影响,气候湿润,年降雨量平均为700—1,000毫米,大半集中在7—9月。全年蒸发量(指自由水面)约为降水量的1.4—1.5倍;年平均气温在14.3—15.1℃之间;全年无霜期为180—210天,
The saline soil in the Yancheng area of northern Jiangsu is mainly distributed to the east of the Chuanchang River, to the north of the Pintu Canal and to the south of the Guan River, with a total area of 12,500 km 2 and a total of 6866,000 mu of arable land. Including Binhai, Sheyang, Dafeng three counties all, Dongtai, Yancheng, Funing three counties across the river in some areas. This area is a plain of beaches deposited by seawater from the Yangtze, Huai and Yellow River alluvial deposits. Flat terrain, slightly inclined to the sea, altitude (in waste Yellow River zero point as the base point) between 2-5 meters in the vicinity of the fight tea canal and the waste Yellow River higher, 4-6 meters; Sheyang Hebei And the lower coastal plain in eastern Binhai, about 1.5 meters, along the Sheyang River in some areas around 1 meter. Climate is a monsoon region of Southeast Asia, roughly Sheyang River bounded by the southern maritime climate, due to close to the North China Great Plains in the north, but also by the continental climate, humid climate, the average annual rainfall of 700-1,000 mm, mostly in the July-September. Annual evaporation (referring to the free surface) is about 1.4-1.5 times of precipitation; annual average temperature is between 14.3-15.1 ℃; annual frost-free period is 180-210 days,
