松江古称华亭，别称有云间、茸城、谷水等，是江南著名的鱼米之乡。唐天宝十年（751年），置华亭县。元至元十四年（1277年）升为华亭府，翌年改为松江府。至清嘉庆十年（1805年）演变为1府（松江）、7县（华亭、上海、青浦、娄、奉贤、金山、南汇）、1厅（川沙）。民国元年（1912年）废府，华亭、娄县合并为华亭县，归江苏省管辖。民国三年（1914年）改称松江县。解放后，苏南行政署设松江专区。1958年3月，松江专区撤消，改隶苏州专区。1958年11月由江苏省划归上海市。1998年2月，国务院批准撤县设区。 Songjiang, once called Huating in ancient times, also known as Yunjian, Rongcheng, and Gushui, is a famous town south of the Yangtze River. In 751 of the Tang Dynasty, Songjiang was named Huating County. In 1277, during the Yuan Dynasty, it was named Huating Prefecture, which was changed to Songjiang Prefecture the next year. Then, in 1805, in the Qing Dynasty, it was developed into Songjiang Prefecture with Huating, Shanghai, Qingpu, Lou, Fengxian, Jinshan, Nanhui, and Chuansha Counties subject to it. In 1912, when the prefecture was abolished, Huating and Lou were merged into Huating County of Jiangsu Province. In 1914, Huating County was changed to Songjiang County. After liberation, the area became Songjiang Special District. In March 1958, it was merged into Suzhou Special District, and in November, Songjiang became a county of Shanghai. Then, in February 1998, the State Council approved Songjiang as a district.

位置     Location    松江区位于长江三角洲内上海市西南部，地处东经121°45’，北纬31°，在黄浦江中上游。区内沪杭高铁、沪苏湖高铁、G60沪昆高速（沪杭高速公路）、G50沪渝高速（沪青平高速公路）、G1503上海绕城高速（同三国道）、G15沈海高速（嘉金高速）、S32申嘉湖高速（机场高速）、轨道交通9号线、22号线等干线形成了纵横交错的道路交通网，是上海连接整个长三角、辐射长江流域的核心区域。松江正日益成为上海西南的重要门户。Located in the southwest of Shanghai in the Yangtze Delta area, at 121.45°E and 31°N, and along the upper and middle reaches of the Huangpu River, Songjiang is a core area to Shanghai and the Yangtze Delta region thanks to its transportation network, including the Shanghai-Hangzhou High-speed Railway, Shanghai-Suzhou-Huzhou High-speed Railway, G60 Hu-Kun Expressway (Hu-Hang Expressway), G50 Hu-Yu Expressway (Hu-Qing-Ping Expressway), G1503 Shanghai Ring Expressway (Tong-San National Highway), G15 Shen-Hai Expressway (Jia-Jin Expressway), S32 Shen-Jia-Hu Expressway (Airport Expressway), Metro Line 9 and Line 22. Songjiang has become an increasingly important gateway to Shanghai in the southwest.    面积      Area    松江区总面积604.64平方公里，占上海市总面积的9.5%，整个区域南宽北窄，略呈梯形，其中陆地面积占87.9%，水域面积占12.1%。The total area of Songjiang is 604.64 square kilometers, accounting for 9.5% of the total area of Shanghai. The whole region is wide in the south and narrow in the north. In the shape of a ladder, 87.9% of the area is land, and the remainder is covered with water.    地势    Topographic Features    松江区地处长江三角洲平原，太湖流域碟形洼地的底部，地势异常低平，有2.7万公顷耕地的地表高程在△3.2m以下。Songjiang is in the Yangtze River Delta and a low-lying area of Taihu Lake Valley, which is unusually low and flat in topographic features with 27,000 hectares only about 3.2 meters above sea level.    气候     Climate    松江区属北亚热带季风区域，四季分明，雨量充沛，夏季炎热潮湿，冬季寒冷干燥。2022年，年平均气温偏高，降水量略少，日照略多。全年平均气温18.0℃，比常年高1.1℃；日照时数1895.5小时，比常年多110.0小时;降水量1095.8毫米，比常年少114.1毫米。年极端最高气温40.5℃，极端最低气温零下5℃。With a pleasant northern subtropical monsoon climate, Songjiang enjoys four distinct seasons and abundant rainfall. Its summer is hot and humid, while its winter is cold and dry. In 2022, the average temperature was significantly higher, with decreased precipitation and more sunshine. The average annual temperature was 18.0 degrees Celsius, 1.1 degrees higher than average. The city had 1,895.5 hours of sunshine, 110.0 hours higher than average, and 1,095.8 millimeters of rainfall, 114.1 millimeters less than average. The highest temperature was 40.5 degrees Celsius, and the lowest was -5.0 degrees Celsius.    水资源     Water Resources    松江区水源属黄浦江水系，上受淀山湖、太湖、浙北天目山等处来水，经黄浦江下泄入江海。境内河渠纵横，池塘众多，是典型的水网地带。所有河流均系感潮河道，每昼夜涨、落各2次。Songjiang’s water resources come from the Huangpu River, which gets its water from Dianshan Lake, Taihu Lake, and Tianmu Mountain in Zhejiang Province and then pours into the sea. All the rivers in the area are tidal; the tides rise and fall twice every day and night.
