Causes of rocky desertification in karst landform

Rocky desertification is the abbreviation of "rocky desertification". Rocky desertification is an evolutionary process in which the contradiction between man and land is prominent, vegetation is destroyed, soil erosion, land productivity is reduced or lost, and rocks with similar desert landscape are gradually exposed under the fragile ecological environment of karst. From the cause of formation, the main factor leading to rocky desertification is human activities. For a long time, natural vegetation has been destroyed continuously, and a large area of steep slope has been reclaimed, resulting in bare surface. In addition, the karst mountain area has thin soil layer, shallow exposed bedrock and strong rainstorm scouring ability. After a lot of soil erosion, rocks gradually emerged, showing the phenomenon of "rocky desertification", and with the passage of time, the degree and area of "rocky desertification" are also deepening and developing. The most direct consequence of rocky desertification development is the loss of land resources. Due to the lack of vegetation and water conservation in rocky desertification areas, it is often accompanied by serious drinking water difficulties for people and animals.
