摘要
综述了人类活动通过影响坡面流水过程、坡地重力过程、河流过程、风沙过程、海岸过程而引起的土壤侵蚀现象,指出人类活动是造成水土流失的重要原因之一。
Soil erosion is a major and serious aspect of the human role in environmental change.Deforestation and agriculture are the prime causes of soil erosion.Human activites also can affect the geomorphological processes,such as mass movement,river and coast erosion,and reactivation of sand dunes,thereby intensify the soil erosion.Through a lack of understanding of the operation of processes and links between different processes and phenomena,humans may deliberately try to protect soil from erosion,but set in train a series of events which were not anticipated or desired.
