The topography and climate of Jiaxing

Jiaxing is located in the northeast of Zhejiang Province, in the hinterland of Hangjiahu Plain in the Yangtze River Delta, and is one of the important cities in the Yangtze River Delta. The city boundary is between 30 degrees 2 1 min north latitude and 3 1 min east longitude 120 degrees 18 minutes to12/degree 16 minutes east, with the sea in the east and Qiantang River in the south. The Grand Canal runs through the whole territory. The city is located at the intersection of rivers, seas, lakes and rivers, at the throat of Hunan Corridor, less than 100 km away from Shanghai, Hangzhou, Suzhou, Lake and other cities, with obvious geographical advantages, especially between Suzhou and Hangzhou, which is a paradise on earth.

The city's land area is 92 kilometers long from east to west, 76 kilometers wide from north to south, and 39 15 square kilometers, including 3,477 square kilometers of plains, 328 square kilometers of water surface, 40 square kilometers of hills and mountains, and 4,650 square kilometers of urban waters.

There are more than 200 hills in the city, scattered on the north bank of Hangzhou Bay in Qiantang River, with the elevation mostly below 200 meters. The highest point of the city is Gaoyang Mountain, which is located at the junction of Haiyan and Haining. The city is a shallow dish-shaped depression near Taihu Lake, and the terrain is generally inclined from southeast to northwest. Due to thousands of years of human reclamation and development, the plain is divided by criss-crossing ponds and canals, and fields, land and water are interlaced, forming a three-dimensional topographic structure of "six fields, one water and three points".
