What are the characteristics of the Pearl River? The difference between Zhuhai and Zhujiang

The Pearl River, also known as the Guangdong River.

It is the second largest river in China and the third longest river in China. The Pearl River originally refers to a 96-kilometer-long waterway from Guangzhou to the mouth of the sea, named because it flows through the famous Haizhu Island (stone), and later gradually became the Xijiang River and the Dongjiang River.

Bac Giang and the Pearl River Delta.

A general term for the rivers on it. The Pearl River originates from the Yunnan-Guizhou Plateau.

The Umeng Mountains are the Maxiong Mountains, which flow through six provinces and regions in central and western China and northern Vietnam, and flow downstream into the South China Sea from eight estuaries.

In 2012, researchers from the Institute of Remote Sensing Application of the Chinese Academy of Sciences used satellite remote sensing technology to measure the length and basin area of the Pearl River, and obtained accurate data, determining that the Pearl River is the second largest river in China. The annual runoff of the Pearl River is more than 330 billion cubic meters, ranking second in the country's river system, second only to the Yangtze River, and seven times the annual runoff of the Yellow River and the Huai River.

10 times. It has a total length of 2,320 kilometers and a basin area of 453,690 square kilometers (of which 442,100 square kilometers are in China and 11,590 square kilometers are in Vietnam. It is the largest river system in southern China and the third longest river in China.

There are 774 large and small rivers in the Pearl River water system, with a total length of more than 36,000 kilometers, abundant river water and numerous tributaries, which have brought superior conditions to the shipping industry of the Pearl River, and the shipping value is second only to the Yangtze River, ranking second in the country. The Pearl River water system is rich in water energy resources, and the famous hydropower hubs such as Tianshengqiao, Datengxia, Lubuge, and Xinfengjiang all belong to the Pearl River water system. Pearl River Basin.

The area is vast, mostly mountains and hills, accounting for the total area, the plain area is small and scattered, accounting for only 55%, and the larger is the Pearl River Delta plain. The Pearl River Basin is rich in tourism resources, and the famous Huangguoshu Waterfall.

Guilin's landscapes are all in the Pearl River Basin.

In the Pearl River system of Guangdong, the Dongjiang River, the Liuxi River and the Beijiang River flow roughly from northeast to southwest, and the Xijiang River and Tanjiang River flow roughly from west to east, and all converge in the Pearl River Delta network river area, and finally flow into the South China Sea by 8 major gates respectively, and the whole water system is a fan-shaped water system.

The topography of the Pearl River Basin in Guangdong is roughly inclined from north to south, and the highest peak, Shikenggang, is 1,902 meters above sea level. The area of the left bank of the main stream of the Pearl River is more than twice that of the right bank. The density of the river network is relatively large, and the density of the river network in the delta area is more than one kilometer per kilometer.

The bending coefficient of the main stream is that the main stream is a flat river. The Pearl River is a composite water system formed by the convergence of the Xijiang, Beijiang, Dongjiang and the Pearl River Delta, originating from the Maxiong Mountain of the Wumeng Mountains of the Yunnan-Guizhou Plateau, flowing through Yunnan, Guizhou, Guangxi, Guangdong, Hunan, Jiangxi 6 provinces (regions) and the northern part of Vietnam, thus forming the characteristics of many tributaries and waterways, and flowing into a network of rivers in the downstream delta, through the distribution of 6 cities and counties in Guangdong Province Humen, Jiaomen, Hongqimen (Li), Hengmen, Modaomen, Jiqimen, The Tiger Leaping Gate and the Cliff Gate flow into the South China Sea.

The difference between Zhuhai and the Pearl River is that Zhuhai is a prefecture-level city, and the Pearl River is a river in Guangdong Province. Zhuhai is located on the west bank of the Pearl River, and Zhuhai is an important city at the southwest end of the Pearl River Delta, located in the southwest of the Pearl River Estuary in Guangdong Province.

Zhuhai, a prefecture-level city in Guangdong Province and a provincial sub-central city, is a special economic zone in China, a core city on the west bank of the Pearl River Estuary, a coastal scenic tourist city, and an important node city in the Guangdong-Hong Kong-Macao Greater Bay Area.

Zhuhai topography.

The geomorphology is obviously controlled by the NE and NW trending tectonic lines, and the Zhuhai area is cut into fault-type uplift and subsidence geomorphic units by NE and NW-trending faults, forming fault-block uplift mountains and subsidence plains. There are many islands and vast sea areas, and there are 146 large and small islands in Zhuhai, which are distributed outside the Pearl River estuary. There are various types of coastal landforms, and the coastline is long, and the mainland coastline of the city is as long as 1,000 kilometers.

The sedimentation of plains and coasts is strong, and there is a vast alluvial sedimentary plain. The coastal mudflats move outwards more quickly, like the sharpening gate. The mouth of the bay on the coast of the mountain harbour has a headland, and there are sand banks and lagoon plains within the bay.

The slope of the ground is gentle, except for the steep slope of the island, the slope of the mainland is gentle. The hilly plateau is mainly composed of granite, and the granite of the Yanshan period is widely exposed in the city.

The Pearl River is characterized by a large volume of water, a large basin area, and a long flow. There are many tributaries, the seasonal change of water level is small, the sediment content is small, and there is no ice period, which flows into the South China Sea.

In the Qing Dynasty, the Pearl River cities entered a period of rapid development, the number of cities increased, and the spatial distribution of cities laid the basic pattern of the spatial distribution of modern and contemporary Pearl River cities. It is a common phenomenon to build cities close to water, but the proximity of Pearl River cities is different from that of the Yellow River system.

The Pearl River system is different from other water systems in that it is a composite water system, with three main streams and several tributaries, each of which has a different natural geographical environment and therefore different urban distribution. In addition, the natural geographical environment of different sections of each main stream is different, and the distribution of cities is also very different. This paper examines and analyzes the distribution and characteristics of cities along the Pearl River in each section of the Qing Dynasty by combing the relevant geographical data.

Notes:

The location of cities in the Pearl River system from the river basically follows the spatial distribution law that the upstream is farther than the middle reach, and the middle reaches are farther than the downstream. The above phenomenon is directly related to the topography and landform of different river sections.

There are many high mountains and valleys in the upper reaches of the three main streams of the Pearl River, mountains and hills in the middle reaches, and low and gentle alluvial plains in the lower reaches. Therefore, some sections of the upper and middle reaches of the Pearl River pass through many canyons or jungles and mountains, and there is no space for building cities and developing agriculture, so the construction of cities lacks geographical conditions and economic hinterland support.

The Pearl River belongs to the hotter areas in southern China, originating from the Yunnan-Guizhou Plateau, flowing through the Pearl River Delta of Guangdong Province, the upper reaches of the Yunnan-Guizhou Plateau and the Hengduan Mountains, the lower reaches of the alluvial plains, the land is fertile, and the region belongs to the Pearl River Delta Economic Circle, one of the three major economic circles in China.

Pearl River is in Zhujiang City, Tuanchun, Guangdong Province. The Pearl River, also known as the Yue River, is the second largest river in China and the third longest river in China. The Pearl River originally referred to a 96-kilometer-long waterway from Guangzhou to the mouth of the sea, named after the famous Haizhu Island (Shi), and later gradually became the general name of the Xijiang, Dongjiang, Beijiang and the rivers on the Pearl River Delta.

The Pearl River has three major tributaries, the Dongjiang River, the Beijiang River and the Xijiang River, and the question is very complicated, but it can be answered briefly, the upper reaches of the terrain are mountainous and plateaus, the middle reaches are mainly hills, and the lower reaches are plains. Economically, it is getting better from the upper reaches to the middle to the lower reaches, and the Pearl River Delta is the most developed.
