Describe the spatial distribution characteristics of annual average solar radiation in Anhui Province.

Describe the spatial distribution characteristics of annual average solar radiation in Anhui Province as follows:

Northern Anhui has a high latitude and a small sun height. The northern part is a mountainous area in the south of the plain. The areas with higher altitude in the south and lower altitude get less solar radiation, while the northern part is rich in solar radiation, mainly sunny days, and the atmosphere has little effect on reducing solar radiation. In summer, the days are longer and you get more solar radiation.

There are four main factors affecting solar radiation: ① Latitude: the lower the latitude, the stronger the solar radiation; ② Weather conditions: There are more cloudy days and less solar radiation in East China; Northwest China is inland, with less precipitation, more sunny days and more solar radiation. ③ Altitude: high altitude, thin air, good atmospheric transparency and strong solar radiation. ④ Sunshine time: long sunshine time and strong solar radiation. For example, in June 5438+10, the Antarctic was extremely daytime and the Arctic was extremely night, and the solar radiation in the Antarctic was much stronger than that in the north.

Anhui was founded in the 6th year of Qing Emperor Kangxi (A.D. 1667). The names of provinces were synthesized by the initials of Anqing and Huizhou at that time, because there were Wanshan and ancient Anhui countries in the Spring and Autumn Period, which was called Anhui for short.

Anhui, located in the central and eastern part of China, is the most dynamic part of the Yangtze River Delta. The province is about 570 kilometers long from north to south and 450 kilometers wide from east to west. The total area is 14.0 1 10,000 square kilometers, accounting for about 1.45% of the land area of China. Anhui has 16 prefecture-level cities, 9 county-level cities, 50 counties and 45 municipal districts, including Hefei, Huaibei, Bozhou, Suzhou, Bengbu, Fuyang, Huainan, Chuzhou, Lu 'an, Maanshan, Wuhu, Xuancheng, Tongling, Chizhou, Anqing and Huangshan.

There are various types of plains, plateaus (hillsides), hills and mountains in Anhui Province, which can be divided into five landform areas, namely Huaihe Plain, Jianghuai Plateau Hilly Area, Western Anhui Hilly Area, Riverside Plain and Southern Anhui Hilly Area, accounting for 30.48%, 65,438+07.56%, 9.99% and 24.938+0 respectively.
