The Yunnan-Guizhou Plateau is between 400 and 3500 meters above sea level. Yunnan-Guizhou Plateau includes the borders of eastern Yunnan Province, Guizhou Province, northwestern Guangxi Zhuang Autonomous Region and Sichuan, Hubei and Hunan provinces. It is the intersection of two groups of mountains in China, which run from north to south and from northeast to southwest. The terrain is high in the northwest and low in the southeast. Wumeng Mountain can be roughly divided into Yunnan Plateau and Guizhou Plateau.

There are contiguous karst mountains in Yunnan-Guizhou Plateau, which are concentrated in the adjacent areas of Yunnan, Guizhou and Guangxi, with a total area of nearly 6.5438+0.7 million square kilometers. Karst landforms account for more than 70% of the total area of Guizhou Province.

Climatic characteristics of Yunnan-Guizhou Plateau.

Yunnan-Guizhou Plateau belongs to subtropical humid area and subtropical monsoon climate (Xishuangbanna belongs to tropical monsoon climate). Although it is a plateau in topography, the climate is significantly different due to different altitude and atmospheric circulation conditions. The amount of solar radiation varies greatly in the meridional distribution of total solar radiation throughout the year, and the western part is larger than the eastern part. Due to high altitude, large temperature difference and strong ultraviolet rays.
