一、前言苏北沿海地区,位于长江以北,陇海铁路以南,串场河以东,约当北纬31°37′—35°,东径119°—122°之间,南自启东,北至赣榆,海岸全长约600余公里,共有土地面积21000平方公里左右。全区气候属于东南亚季风区,约以射阳河为界,在南部因受海洋的影响属海洋性气候,北部属华北平原则兼有大陆性气候,由于本区受海洋与内陆气候的影响,常年多风,所谓季风,全年最多风向为东南风,年平均风速为4.9—7.4米/秒,尤以夏秋之交常受太平洋台风袭击,7、8月最多,最大台风曾达11级(风速29.2米/秒),全年暴风(烈风以上)日数达70余日,故沿海风灾危害是较严重的,它给本区农业生产上,特别是在夏秋作物成熟阶段带来了最不利的条件,并给国家带来了巨大之损失。
I. Introduction The coastal areas of northern Jiangsu are located to the north of the Yangtze River and to the south of the Longhai Railway and to the east of the Changchang River. When the latitude 31 ° 37’-35 ° north latitude and 119 ° -122 ° east longitude, Ganyu north, the coast of about 600 kilometers in length, a total area of 21,000 square kilometers of land. The climate belongs to the monsoon region of Southeast Asia, about the Sheyang River as the boundary, due to the impact of the ocean in the southern maritime climate, the northern part of the North China Plain is both continental climate, due to the region affected by the ocean and the inland climate , The year-long winds, the so-called monsoon, the annual maximum wind direction for the southeast wind, the average annual wind speed of 4.9-7.4 m / s, especially at the turn of the summer is often hit by the Pacific typhoon, most in July and August, the largest typhoon had reached 11 (Wind speed 29.2 m / s) and the number of storms (above the gale) lasts for more than 70 days. Therefore, the damage caused by coastal windstorms is more serious, which brings the most unfavorable effects on the agricultural production in this area, especially in the maturing stage of summer and autumn crops Conditions, and brought great losses to the country.
