Test analysis:

The hydrological characteristics of (1) River are analyzed from the aspects of water level, water quantity, sediment concentration and ice age. Wujiang River is located in the subtropical monsoon climate zone, with large runoff and obvious seasonal changes. As can be seen from the figure, the Wujiang River has a large drop, which indicates that the flow speed is fast and the water energy resources are abundant.

(2) The causes of soil erosion are natural and man-made reasons. Natural causes are mainly heavy precipitation and low vegetation coverage, while human causes are mainly caused by unreasonable human activities such as vegetation destruction, steep slope land reclamation and mining. The solutions can be explained according to the reasons, mainly from the perspective of vegetation, such as adjusting agricultural structure, returning farmland to forests, improving agricultural ecological environment and controlling population growth.

(3) Industrial location factors generally include raw materials, markets, transportation, labor, science and technology and policies. The main geographical advantages of developing pepper processing industry in Guizhou Province are abundant raw materials (the largest pepper production scale in China), low labor cost (Guizhou Province is a developing region) and large market demand (Guizhou Province is one of the major spicy provinces in China).

(4) "cool summer capital Guiyang" is because Guizhou Province is located in Yunnan-Guizhou Plateau, with high altitude and low temperature in summer; "Ethnic original ecology, southeast of Vientiane" is because Guizhou Province is located in the southwest of China, inhabited by ethnic minorities, and its ethnic culture is diverse and unique. "Red culture continues to write Zunyi red classics" because Zunyi is a revolutionary historical memorial and a red tourist attraction.
