地理\n\n- 坐标：31.81306, 121.65739[^wikidata]\n\n启东市地处东海、黄海、长江交汇之处，长江入海口的北岸，三面环水，整体呈三角形。地表大部分为沿海冲积平原，地势平坦，自西北向东南略有倾斜。北临南黄海，东与日本隔海相望。西与江苏省海门市相接壤，南靠长江入海口北支，其中境内大部分与崇明岛隔江相望，另有部分沙洲与崇明岛接壤。启东市水系属于长江水系，地下水位常年处于1.2—1.6米。 启东市属于北亚热带湿润气候，一年四季分明，气温温和，有充足的光照和雨水，无霜期较长，春季气候多变，秋季气爽宜人。年均气温为15℃，年均降水量为1037.1毫米，年均相对湿度为81%，年均高于35℃的日数为5天，最多的一年为1964年的18天；年均风向最多为东南风，年均风速为3.5m/s；年均日照时数为2073小时；年均无霜期为222天。\n\n## 历史\n\n在汉朝以前，启东境内还是一片汪洋。唐朝初期境内涨出东洲和布洲两沙岛，后合并为东布洲。五代设海门县于东洲，县治在今启东吕四附近。元至正至清康熙时期，启东境内大部分复为大海，仅存吕四镇地区。18世纪中叶后，在境内南部先后涨出了惠安沙、永丰沙、永昌沙等10多个沙洲，时称崇明外沙，这片沙洲至民国初年连成一片。 因成陆时期不同，启东所辖地方曾分属三个县管辖。北部吕四地区，又称为“北沙”，在宋、元、明、清时属海门县，1912年-1942年间属南通县；中部又称为“下沙”，原属海门县；南部又称崇明外沙，原属崇明县。1928年3月，北部、中部、南部三地合并分设启东县，首任县长袁希洛。 1942年9月，为适应抗战形势需要，启东县与海门、崇明及通东地区地区合并为东南行署管辖区，属苏中四分区[^zhwiki]。",
