Nanjing
Known as "natural geological museum", the Yangtze River floodplain, water-rich soft soil, hills, karst and other geomorphic units coexist? . Nanjing belongs to the hilly area of Ningzhenyang, mainly with low mountains and gentle hills. Low mountains account for 3.5% of the total land area, hills account for 4.3%, hills account for 53%, and plains, depressions, rivers and lakes account for 39.2%.
Ningzhen Mountain Range and Laoshan Mountain in the north of the Yangtze River run through the middle of the city. There are Hengshan Mountain and Donglu Mountain in the south, which are located in the southern boundary of the hilly area of Qinhuai River Basin. Nanjing's plane position is long from north to south and narrow from east to west, forming a positive north-south direction; The straight-line distance between north and south is 150km, the middle is 50-70km wide from east to west, and the north and south ends are about 30km wide from east to west.
The southern part is a geomorphic complex composed of low mountains, hills, valley plains, lakeside plains and beaches along the river. Nanjing enters spring in April 1, summer in June 8 and autumn in September 18. Winter is about 165438+ 10/2.
Nanjing is short in spring and autumn, long in winter and long in summer, and the temperature difference between winter and summer is significant. Due to the change of atmospheric circulation and the continuous afforestation in Nanjing, the summer heat in Nanjing is much lower than that in other cities, so the name "stove" was removed.
