西南喀斯特山区具有独特的喀斯特土壤特征与土壤侵蚀的环境效应,普遍面临着因土壤侵蚀导致的"石漠化"问题.已有研究认为,在气候、地质地貌、植被和人为活动等环境因素的影响下,喀斯特山区土壤侵蚀以混合侵蚀方式进行.但由于对喀斯特山区土壤侵蚀过程的认识不同,致使研究者得出土壤侵蚀强度差异较大的研究结果.有关喀斯特土壤侵蚀系统研究重点应该在土壤侵蚀机制、土壤侵蚀分级强度与土壤合理流失量等方面开展研究.

Karst mountainous area commonly faced with the risk of soil erosion leading to lithic desertification especially in Southwest Chinas which has particular soil characteristics and its environmental effect. The current research considered that the soil erosion proceeded in mingled forms affected by the closely related element including weather, geological and geomorphologic factors, vegetable and human activities. But different researcher reported the soil erosion intensity with bigger difference guided by their own thought on karst soil erosion process. The systematic karst soil erosion research should put emphasizes on the soil erosion mechanism and the soil erosion intensity classification and and the assume of reasonable soil loss.
