Abstract
Based on the research of soil erosion and soil and water conservation in karst areas in China in recent years, the status and progress of soil erosion and soil and water conservation in karst areas in China are discussed. The results show that the soil and water loss in the karst area mainly has two types of soil erosion: surface soil erosion and underground soil erosion. Soil and water loss management in karst areas mainly adopts measures to adjust land use structure, increase vegetation coverage, carry out slope-to-ladder construction, and promote clean energy applications. Different governance models should be adopted for different landform types, different landform parts, different slopes, and different levels of rocky desertification in karst areas.
Highlights
Soil and water loss refers to the damage and loss of water and soil resources and land productivity caused by external forces such as water power, gravity, wind, and freeze-thaw and human activities
Soil erosion in the ground, or soil leakage, is a special type of soil and water loss that occurs in karst rocky desertification areas
Domestic scholars have carried out applied research on karst rocky desertification control in karst areas such as Guizhou, Guangdong, and Guangxi, and summarized the soil and water conservation models in karst areas
Summary
Soil and water loss refers to the damage and loss of water and soil resources and land productivity caused by external forces such as water power, gravity, wind, and freeze-thaw and human activities. Soil and water loss in karst areas mainly includes surface water and soil loss and soil erosion in the ground
