This data comes from Baidu map, and the final result is subject to Baidu map data.
46', latitude 2211'12 "to 22 46' 35". The whole city covers an area of 1.80 square kilometers, facing Shenzhen and Hong Kong across the sea in the east and 5 1 nautical mile from zhongshan port to Hong Kong. It is bordered by Zhuhai in the southeast, adjacent to Macau, and 60 kilometers from Shi Qi to Macau; West and southwest are adjacent to Jiangmen City, Xinhui City and Doumen County; The north and northwest are connected with Nansha District and Shunde City in Guangzhou; Ma 'an Island and Damao Island are located in the east and west of the city along the Pearl River Estuary.
topography
The terrain of Zhongshan City is like a clenched fist, long and narrow from north to south and short and narrow from east to west. Terrain configuration is divided into northern plain, central mountain and southern plain. The plain area accounts for about 68% of the city's area, the mountains account for 25%, and the rivers account for 7%. The city is surrounded by water on three sides, and its main waterways flow from northwest to southeast. More than 5,000 rivers and artificial irrigation and drainage channels are criss-crossed, interconnected and distributed in a radial fan shape with sharp corners as the apex. The topography of Zhongshan was formed on the basis of South China paraplatform after long-term climate change and wind and rain erosion. Now it is dominated by alluvial plains, with low hills and plateaus scattered among them. Zhongshan east zone
The basement of the plain is granite, which belongs to silting and floating origin. The city's plain covers an area of about 1242 square kilometers, which is divided into three major areas by low mountains and hills: the northern plain, starting from Zhangjiabian in the east, reaching Guzhen in the west, Huangpu in the north and near Shi Qi in the south, with an area of about 850 square kilometers, making it the widest plain in the city; The southern plain, also known as Jindouwan Plain, borders Zhuhai in the south and southeast, Modaomen Waterway in the southwest, and Wuguishan low hills and Baishuilin high hills in the north and northwest, covering an area of about 1 1O square kilometers, making it the second largest plain in the city. Southwest Plain, located on the east side of the middle reaches of Modaomen Waterway, covers an area of nearly 100 square kilometers, with low terrain, mostly below sea level and high groundwater level, which is a low-level soil distribution area in the city. Tidal flats are mainly distributed in the eastern coast, southwestern coast and river banks of the city, and some of them have crossed the outside of Hengmen, covering an area of about 150 square kilometers. The city's coast is 26 kilometers, close to the Lingdingyang area of the Pearl River Estuary, and most of them belong to the muddy coast. Due to the continuous downward deposition of alluvium and the continuous expansion of beach area, Xijiang River and Beijiang River estuary extend outward year by year, becoming a new alluvial plain. The hilly platform is located in the south of the central part of the city, covering an area of about 400 square kilometers. With Wugui Mountain as the main vein, it forms a low mountain and hilly platform with the surrounding mountains.
The elevation of the main body (3 pieces) of Sun Wen West Road Pedestrian Street is mostly between 100 and 300m, and there are more than 10 peaks over 300m. There are 9 mountain ranges in China, including Zhuoqi Mountain, Qishan Mountain, Changyao Longshan Mountain, Dajian Mountain, Nantai Mountain, Zhoudongkeng Mountain, Baiyunjing Mountain, Wugui Mountain and Feiyun Dongshan Mountain, among which Wugui Mountain is the highest, with an altitude of 53 1 meter. The mountains are continuous and majestic, and the southeast slope extends to Zhuhai city. Penny Mountain is located in the west of Wugui Mountain and reaches Modaomen Waterway in the west. Its area is smaller than Wugui Mountain, and its basement is mainly granite with strong weathering resistance. The mountain is steep, with five peaks over 300 meters, and the highest peak is Baishui Linda 473 meters. The low hills in Wugui Mountain and Penny Mountain are basically covered by vegetation; There are many trees and shrubs in the valley. On the periphery of mountainous hills, the height gradually decreases, which is a vast hill and an obvious platform with the same height, mainly distributed in Shaxi, Zhangjiabian and other towns. The altitude of the platform is generally between 25 and 50 meters, and the weathered layer is thick. Most of the fruit gardens and dry fields have been developed, and the cultural and economic activities in the city are mainly concentrated in this area. Rural settlements and highway access are also related to the platform.
geology
The exposed strata in Zhongshan City are mainly Cenozoic Quaternary, with Paleozoic, Mesozoic and Proterozoic Sinian strata exposed sporadically in the north, middle and south. Cenozoic Quaternary is widely distributed in China, which can be divided into eluvial, alluvial, alluvial and marine deposits according to genetic types. The geological structure system belongs to the central Guangdong depression in the northern, northeastern and central Guangdong depression belts of South China fold bundle. The central Guangdong depression is divided into several uplift fault bundles, and Zhongshan is located in the southwest section of Zengcheng-Taishan uplift fault bundle. The fault structures in the city are developed, widely distributed and exposed obviously. According to its trend, it can be divided into northeast, northeast, northwest and east-west arrays. Fold structures, because sedimentary rocks are not exposed much, but also damaged by fault changes and magma intrusion, are mostly incomplete, with only two obvious groups: Shenwan fold and Yongmo fold. Mineral resources, due to the simple stratigraphic distribution, mineral resources are not rich. Solid combustible minerals: Peat soil is the only fuel mineral in Zhongshan, distributed in Zhangjiabian, with oil content of about 10% and some as high as 16% ~ 18%. The quality is good, but the reserve is only about 6.5438+0 million tons, the topsoil is thin and the mining cost is low, so it can be used for small-scale open-pit mining in some areas. Metal minerals include magnetite, wolframite and placer tin. Because of small reserves, low grade, scattered veins and low mining value. Building minerals: oyster shells, widely distributed in the northern delta plain, are not deeply buried, and the thickness can reach 2 to 4 meters. They are distributed in strips and layers, rich in calcium, and are one of the commonly used building materials in cities. Stone is mainly granite, mainly distributed in the hilly area of Wugui Mountain. Kaolin is mainly distributed around the city and at Zhangjiabian.
hydrology
The density of river network in Zhongshan City is one of the larger areas in China. Waterways and rivers receive water from the west and north rivers, and the water begins to rise in April every year, and gradually drops at 5438+00 in June, and the flood season lasts for more than half a year. Northeast is the Li Hongqi waterway of Beijiang River system; The middle part is the East China Sea Waterway, and the lower branches are the Jiya Waterway and Xiaolan Waterway, which merge into the Hengmen Waterway. The west is the main stream of Xijiang River, and it goes to sea at Modaomen. Huangpu Waterway and Huangshali communicate with each other, forming a criss-crossing river network. There are 289 tributaries in the city, with a total length of 977.438+0 km. The main waterways are Jiya Waterway, which connects Ronggui Waterway in the north, and Dongfeng and Fusha Town in the north on both banks.

The waterway discharges the torrent of Xijiang River, and the two banks become flood control areas in Zhongshan City. Xiaolan Waterway is connected to Ma Ning Waterway in Shunde City in the north and flows into the urban area at Ying Ge Mouth. Both sides pass through Xiaolan, Tanbei and Port Town; The east coast passes through Dongfeng and Fusha Town, joins Jiya Waterway at Dananxu and flows into Hengmen Waterway to go to sea. The total length is 3 1 km and the width is 150 to 300 meters. The waterway discharges the upstream Xijiang flood, and the two banks become the main flood control areas in the city. Hengmen Waterway connects Xiaolan Waterway, Jiya Waterway and Shi Qi Waterway, passes through Zhangjiabian and Zhongshan Port Area, and flows out of the Pearl River Estuary through Hengmen. Total length 12km, width 800 ~1000 m. Huangshali is connected to Jiya Waterway in the west, flows eastward through the boundary between Huangpu and Sanjiao Town, and flows into Li Hongqi Waterway in Shatou, Shiji, with a total length of10km and a width of130 ~150m. It is the irrigation and drainage river of farmland in Huangpu Town, Sanjiao Town and Minzhong Town, and also the main flood drainage tributary of Jiya Waterway. Huangpu Waterway connects Jiya Waterway in the west and Li Hongqi Waterway in the east, with a total length of 1 1 km and a width of 100 to150m. It is the irrigation and drainage river of farmland in Huangpu and Nantou Town. Shiqi River passes through the city center, flows northeast through the border area between suburbs and Zhangjia, flows out of Donghekou Sluice and flows into Hengmen Waterway. From west to south, it passes through Huancheng District and Banfu Town, reaches Xihekou Sluice and exits Luozhoumen, with a total length of 46 kilometers and a width of 80 to 200 meters. Beitaixi originated in Wugui Mountain, between the wind-blown Luodai Peak and Meihua Dome. The trunk flows to the north and northwest, flows through Binglang Mountain and Shiying Bridge, turns west to Meihuakeng, flows out of Shiguta, Nankengkou, Ziniwan and other villages through manger, flows into Shi Qi through Beitai Bridge of Dadong Yangshan Guankouqi Highway, and flows around the northern foot of Huzhou Mountain. It is 23 kilometers long and 6 to 12 meters wide. The Dahuan River (small hidden surge) originates between the main peak of Wugui Mountain and the peak of Luodai, which is blown by the wind. The trunk flows to the north and northeast, and the water flowing through Huitongzi Pit in Daliao Village passes through Laowulin, exits the west fork, passes through Dahuan Village and flows into Hengmen Waterway. It is 25 kilometers long and 8 to 15 meters wide.
