From the perspective of developing tourism, this paper compares the regional differences between the Qinghai-Tibet Plateau and the hills in the south of the Yangtze River (list comparison)

The annual average temperature in the hilly areas of the south of the Yangtze River 16 ~ 20℃. Summer is extremely hot and lasts for a long time. The average temperature in the hottest month is 27 ~ 31℃. The extreme maximum temperature is over 40℃, 44℃ in Ji 'an and 44.9℃ in Shuixiu. It is warmer in winter, with the lowest monthly average temperature of 3 ~ 9℃. The active accumulated temperature above 10℃ is 5000 ~ 6000℃, and the frost-free period is 235 ~ 300 days. Crops in the low hilly basin can be harvested three or two times a year; Crops in mountainous areas are harvested twice or once a year. There is no barrier in the north, and the absolute minimum temperature in winter can reach-12℃, which is not conducive to the overwintering of subtropical economic trees.

The Qinghai-Tibet Plateau has high altitude, dry and thin air, strong solar radiation and low temperature. Due to the complex and changeable terrain, the climate of the Qinghai-Tibet Plateau itself changes greatly with different regions. Generally speaking, the rainfall on the plateau is less than that on the uplifted Qinghai-Tibet Plateau.

Conclusion: The temperature difference in hilly areas of the south of the Yangtze River is large, and the Qinghai-Tibet Plateau is dry and cold all the year round. Spring and autumn are the peak tourist seasons in the hilly areas of the south of the Yangtze River. There is little difference between the four seasons in the Qinghai-Tibet Plateau, but autumn is the main season.
