What's the difference between the Yangtze River Delta and the Pearl River Delta?

First, the location is different.

1, the Pearl River Delta, located in the middle of Guangdong Province, China, is both a geographical region and an economic region.

The new Pearl River Delta urban agglomeration includes "Guangzhou-Foshan-Zhaoqing+Qingyuan+Yunfu+Shaoguan", "Shenguanhui+Shanwei and Heyuan" (Shenzhen, Dongguan, Huizhou+Shanwei+Heyuan) and "Pearl River+Yangjiang" (Zhuhai, Zhongshan and Jiangmen+Yangjiang).

The Pearl River Delta consists of 9+6 cities. The Greater Pearl River Delta region also includes Hong Kong and Macao Special Administrative Regions.

2. The Yangtze River Delta is an alluvial plain before the Yangtze River enters the sea, the largest economic zone in China, the economic center with the strongest comprehensive strength in China, an important international gateway in the Asia-Pacific region, an important advanced manufacturing base in the world, and an area where China takes the lead in becoming a world-class urban agglomeration.

According to the regional planning of the Yangtze River Delta approved by the State Council in 20 10, the Yangtze River Delta includes Shanghai, Jiangsu and Zhejiang provinces with an area of 2 10700 square kilometers. It accounts for 2. 19% of the land area. Land area 186802.8 square kilometers, water area 23937.2 square kilometers.

Second, the climate is different.

1, the Yangtze River Delta is dominated by subtropical monsoon climate. The annual average temperature, the annual average maximum and minimum temperatures all increased significantly, and the warming rate was higher in winter and spring and the lowest in summer.

The warming rate of big city stations is obviously higher than that of small towns and medium-sized city stations, and the urbanization effect is basically a warming effect on the temperature in big cities, with the largest warming rate and contribution rate to the average minimum temperature and the smallest contribution rate to the average maximum temperature. The trend of temperature change and the contribution rate of warming rate, warming rate and urbanization effect in the Yangtze River Delta region are consistent with those in other regions.

2. The Pearl River Delta has a subtropical climate, which is warm and humid all year round. The annual average temperature is 2 1 ~ 23℃, with the highest Leng Yue 13 ~ 15℃ and the hottest month above 28℃. There are frequent typhoons from June to 10, with concentrated rainfall and the hottest weather. The annual average precipitation exceeds1500mm.

The rainy season is synchronized with the high temperature season, with fertile soil and rivers, which is beneficial to agriculture. Below 200 meters above sea level, the terrain is flat. The weather is hot and rainy, mainly subtropical monsoon climate.

The tropical climate of South Asia in the Pearl River Delta is characterized by four unknown seasons, no snow in three winters, evergreen trees, evergreen fields and no frost. Zhu Kezhen said in his book "Special Climatology" that the tropics are places where "all seasons are summer, and it rains in autumn". He thinks that the south of Wuling Mountain is in the tropics. But the Pearl River Delta is in the subtropical zone.

Third, the ecological environment is different.

1, the Yangtze River Delta region has complex ecosystem types and diverse surface coverage. The main land use types include cultivated land (including paddy field and dry land), woodland (including sparse woodland, shrub woodland, sparse woodland and other woodland) and grassland (including high coverage grassland, medium coverage grassland and low coverage grassland) 14 subcategory.

Waters (including rivers, lakes, reservoirs, pits and beaches), construction land (including urban land, rural residential land and bus construction land) and unused land (including bare land and bare rock land).

2. The Pearl River Delta is composed of landform, climate, hydrology, vegetation, animals and other elements from the geographical environment. The Pearl River Delta is a subtropical delta, which is different from the Yellow River. Terrain and hydrology are characterized by good water network, numerous tributaries, wide rivers and deep water.

The climate is rich in heat and radiation; Vegetation grows vigorously, with many kinds and animals, which is very beneficial to industrial and agricultural production. In terms of types, the Pearl River Delta is similar to tropical deltas such as the Red River Delta and Mekong Delta.
