Who can give me the geographical knowledge of Taiwan Province Province and the Pearl River Delta?

Pearl River Delta 1) Location: The Pearl River Delta is located in the south-central part of Guangdong Province, adjacent to Hong Kong and Macao. The Tropic of Cancer runs through its northern part and borders the South China Sea, which is the mouth of the Pearl River. (2) Natural features: The Pearl River Delta is a composite delta consisting of Beijiang River, Xijiang River Delta and Dongjiang River Delta, with an altitude of about 50 meters and an area of about 1. 1.000 square kilometers. In the meantime, the hills are strewn at random, the rivers are vertical and horizontal, the soil layer is deep, the soil is fertile and the irrigation is convenient. It belongs to subtropical monsoon climate, rich in heat and long growing period, and can be harvested three times a year. It is rainy in spring, hot and humid in summer, frequent typhoons in summer and autumn, less cold in winter and obvious changes in four seasons. The flood season of rivers is from April to September. (3) Economic development: The Pearl River Delta is one of the four famous industrial bases in China, and together with the Yangtze River Delta, it is called the two engines of China's economy. At present, the economic growth mode of the whole Pearl River Delta has changed from extension to connotation, from labor-intensive to capital-technology intensive, from extensive management to intensive management, from traditional industry to modern industry, from urban-rural division to urban-rural integration, forming a knowledge-technology intensive industrial system with high starting point, high standards and large-scale tertiary industry and competitive main industrial clusters. In addition, it has formed comprehensive advantages in transportation, communication, finance, information consultation, high technology, tourism, culture and foreign exchange. As far as geographical advantages are concerned, they can be summarized as follows: ① Unique geographical advantages: superior natural geographical environment, adjacent to Hong Kong and Macao, facing Southeast Asia, natural sea lanes and good ports, and convenient foreign trade. Superior popularity advantage: It is one of the famous hometown of overseas Chinese in China, which is conducive to attracting investment. ③ Strong complementary advantages: As one of the international financial centers, Hong Kong is rich in capital, information resources and human resources, but the labor cost is too high and the market capacity is small; Macao is a world-famous tourist city, but its development space is narrow. The Pearl River Delta is rich in natural and human resources, and the rapid economic development has attracted a large number of cheap labor and technical personnel from the mainland, which, coupled with the radiation of the economy, has formed a huge consumer market. ④ Unique advantages of economic follow-up: Compared with Hong Kong, Macao and developed regions, the Pearl River Delta is a late-developing region. The geographical advantages adjacent to Hong Kong and Macao not only provide a lot of money and technology for local economic development, but also accumulate rich experience and lessons. ⑤ Abundant talents and technical advantages: Due to the rapid economic development and high economic benefits of the Pearl River Delta, it has attracted a large number of various technical and management talents in the Mainland, forming its unique technical and talent advantages. (4) Ecological environment and natural disasters: In addition to the environmental pollution caused by the discharge of waste water, waste gas and waste residue due to the development of industrial production in recent years, the oil pollution in the Pearl River Estuary caused by traffic and oil exploitation, as well as the red tide and salty tide in the Pearl River Estuary are all noticeable. Strong winds, heavy rains and storm surges caused by typhoon landing in summer and autumn are extremely harmful. Affected by human activities and the rapid changes of delta rivers, the flood threat is becoming more and more serious. (5) Tangji agriculture: ① the process of ecological cycle: the combination of mulberry, silkworm and fish can save the cost of feed and fertilizer. A. Use low-lying land, dig a pond, and pile the soil into a foundation. B. In pond culture, the pond mud is used as fertilizer to grow crops. C. Crops can also be used as feed, and ponds and bases are cultivated with each other to form a benign "land-water mutual cultivation". ② Classification: According to the different crops planted on the embankment, it can be divided into mulberry-based fish ponds, sugarcane-based fish ponds and fruit-based fish ponds. ③ Agriculture: accurate land use can produce rice, silk, sugar cane, fruits, flowers, fish and shrimp. ④ Industry: Due to the supply of the above-mentioned raw materials, the agricultural product processing industry is developed. ⑤ Landscape change: Due to the establishment of special economic zones and the development of industries and small towns, many fish ponds have been filled with soil, and the land use is in a transitional state as factories and houses. (6) Urbanization and migrant workers' mobility: With the development of economy, especially industrialization, urbanization in the Pearl River Delta region has developed rapidly, with the urbanization level reaching 73%, far higher than the national average. A contiguous urban agglomeration has been formed, with a high concentration of population and industry and strong economic radiation, and a "Pan-Pearl River Delta Economic Circle" has been formed, including Guangdong, Fujian, Jiangxi, Hainan, Hunan, Sichuan, Yunnan, Guizhou, Hong Kong and Macao. Another notable feature of the population composition in the Pearl River Delta region is the large number of migrants. The rapid economic development not only attracts outstanding talents from many parts of the country to work and settle here, but also attracts a large number of migrant workers, becoming one of the main destinations of migrant workers in China. According to incomplete statistics, plus migrant workers, Guangdong's population has exceeded 100 million, making it the most populous province in China. TW absolute position: 120E~ 122E, 22N~25N relative position: southeast coast of Asian continent, west coast of Pacific Ocean, north of Philippines, southwest time zone of Ryukyu Islands: GMT+8: 00 Taipei Taiwan Province Island is located in the western Pacific Ocean, which looks like a sweet potato, and its east coast is the Pacific Ocean, about 75km away from Japanese Ishigaki Island. The Taiwan Province Strait separates the west coast from Chinese mainland. The island covers an area of 35,798 square kilometers, which is long and narrow from north to south and long and narrow from east to west. The terrain is high in the east and low in the west. The terrain is dominated by mountains, hills, basins, platforms and plains. Mountains and hills account for about two-thirds of the total area of the island. Taiwan Province Island is located at the junction of Eurasian plate and Philippine plate, and the crust is squeezed and uplifted to form mountains, which run through the whole Taiwan Province from north to south, with the central mountains as the main body and high terrain. From here, it gradually descends to the east and west sides to low and flat hills or platforms, and is finally alluvial by rivers into low and flat plains. Basins are scattered among mountains, hills or platforms. Among them, plains, hills and terraces are mainly distributed in the west. As Taiwan Province Island is located in the center of East Asia island arc, bordering on Taiwan Province Strait, an important international waterway, it has important strategic value. There are five Sinian-trending mountains in the whole island, which are divided into central mountains and eastern coastal mountains. From north to south, the Central Mountain consists of Snow Mountain Range, Central Mountain Range, Yushan Mountain Range and Alishan Mountain Range. Taiwan Province Province has the widest mountainous terrain, many of which are over 3,000 meters, among which 100 peaks have been selected as Baiyue Mountain. The Central Mountain Range starts from Su 'ao in the north and ends at Eguanbi in the south. It is the backbone of Taiwan Province Island and the watershed of rivers in the east and west. The main peak of Yushan Mountain is 3952 meters high, which is the highest peak in the whole island. It is also the highest peak in Northeast Asia. Hills are distributed between mountains and plains, mainly in Taozhu Temple and Peninsula. The leveling principle is distributed in the southwest coastal and eastern mountain valleys, accounting for 30% of the total area, with Jianan Plain in the southwest being the largest, Changhua Plain, Yanglan Plain, Pingtung Plain and Taitung (East China) longitudinal valley (the dividing line between Eurasia Plate and Philippine Sea Plate). Terrain is flat, but the platforms with higher terrain are Linkou Platform, Taoyuan Platform, Dadu Platform and Bagua Platform. As far as basin topography is concerned, Taibei Basin, Taichung Basin and Puli Basin are typical. Because Taiwan Province Province is located in the volcanic seismic belt around the Pacific Ocean, there are various volcanic landforms, mainly including the Datun volcano group in Keelung in the north, the coastal mountain volcano group in the east (including Green Island and Lan Yu Island) and the Penghu volcano group in the outlying islands. But at present, there is no obvious active volcanic activity on the island. Altitude limit: lowest point: 0 m in the South China Sea; Highest point: Yushan 3952 meters. There are 0/29 large and small rivers/kloc-,and only 6 rivers exceed 100km, namely Zhuoshui River, Gaoping River, Danshui River, Dajiaxi, Zengwenxi and Daduxi. The turbid water stream in the middle is the longest river in Taiwan Province Province, while the Gaopingxi river basin in the south is the widest. Other major rivers are Keelung River, Fengshan River, Da 'anxi River, Daduxi River, Bazhangxi River, Xiuguluanxi River and Lanyangxi River. The average annual rainfall is 2,500mm (3.5 times of the average rainfall on land in the world, but the annual water resources allocated per capita is only half of the world average). Huoshaoliao, located in Pingxi Township, Taibei County, has the highest annual rainfall in Taiwan Province Province and East Asia. There are not many natural lakes in Taiwan Province Province, the largest of which is Sun Moon Lake, with an area of only 4 square kilometers. Most of the rest are artificial ponds and reservoirs, such as Hutou Valley, Zengwen Reservoir, Wushantou Reservoir and Shimen Reservoir. The affiliated outlying islands of Taiwan Province Island include Lan Yu, Green Island, Little Ryukyu Island, Kameyama Island, Huamian Island in the northeast of Keelung, Pengjiayu Island and Diaoyutai Liyu, with a total of 22 islands. Volcanic Island: Most of the outlying islands around Taiwan Province Province belong to volcanic islands. Among them, the rock composition of Penghu Islands is basalt, which is caused by the short-term submarine expansion of the South China Sea, and the rest is andesite. The last eruption on Kameyama Island was about 7000 years ago, and there is still volcanic activity. Coral reef islands: most of them are distributed in the southern waters. Special case: Jinmen and Mazu are islands, because the coastal hills are affected by the relative rise of sea level. Climate Taiwan Province Province is bounded by the Tropic of Cancer, with tropical monsoon climate in the south and subtropical monsoon climate in the north (southwest wind blows in summer and northeast wind blows in winter). It is warm in winter (the mountainous area is lower than the flat, and the northern part is lower than the southern part), hot in summer (except the mountainous area, the rest are above 20℃) and rainy (the mountainous area is higher than the flat, the east coast is higher than the west coast, and the northern part is higher than the southern part). May and June are rainy seasons, and June to September is typhoon season. Natural disasters in Taiwan Province Province: There are three or four typhoons every year on average. Typhoon is the main factor affecting the climate in Taiwan Province Province. In addition to the damage caused by strong winds, the instantaneous rainfall caused by tropical depression is also easy to cause heavy rain. Because of the uneven distribution of rainfall in space and time, it is easy to cause floods and mudslides. On the other hand, tropical islands are prone to drought in winter due to insufficient rain brought by typhoons in summer. Earthquakes: As Taiwan Province Province is located at the junction of plates, earthquakes are frequent, with an average of more than 100 felt earthquakes every year, and catastrophic strong earthquakes occur every 5- 10 years. The latest major earthquake was19.21earthquake with a magnitude of 7.3 on the Richter scale in Nantou county in 1999. Cold damage: Although it is warm in winter in Taiwan Province Province, there are occasional cold air masses from the mainland, and the temperature drops below 10℃, resulting in the loss of agricultural and fishery crops. West coast (beach coast)-there are many beaches, sandbars and lagoons, the coast is flat and monotonous, and the sea is shallow. East coast (rocky coast)-the mountains are adjacent to the deep sea, the coastal plain is narrow and the sea water is deep. The northern coast (rocky coast)-rocky headland and bay alternate, which is the most tortuous section of the coast of Taiwan Province Province. South coast (rocky coast)-mainly coral reef topography. Regional Topographic Mountains Central Mountain Range-the longest and largest mountain range in Taiwan Province Province, starting from Suao in the north and reaching Luanbi in the south. It is 330 kilometers north-east, south-southwest and runs through the whole island. Known as the roof of Taiwan Province Province. Snow Mountain Range-Located in the northwest of Taiwan Province Province, it starts from Sanminkao in the north and ends at Zhuoshuixi in the south, with a total length of 180 km. It is northeast and southwest. Yushan Mountain Range-located on the west side of the Central Mountain Range, bounded by Zhuoshuixi and Xueshan Mountains in the north and Qishan Mountain in Kaohsiung County in the south. Alishan Mountain Range-Located on the west side of Yushan Mountain Range, it starts from the upper reaches of Zhuoshui River in the north and reaches the upper reaches of Zengwen River in the south, with a length of 135km and a north-south trend. The mountains are low, and there are no peaks over 3000 meters. Coastal mountain range-starts from the south of Hualien Xikou in the north and reaches the north of Taitung in the south, showing a north-south trend, with a length of148km. The northern section is low, and the southern section is as high as 1, 500m m.
