摘　　要：西南岩溶区的土壤侵蚀问题严重威胁区域的生态环境安全和经济的可持续发展,从20世纪后期至今,研究者们对该区的土壤侵蚀进行广泛的研究,取得显著成果.在系统分析把握已有研究现状的基础上,阐明西南岩溶区土壤侵蚀的特点;同时,从短时间(短期,<50 a)、中时间(中期,<100 a)和长时间(长期,>100 a)3种不同时间尺度入手,分析和总结目前西南岩溶区土壤侵蚀的研究方法、现状和不足.针对西南岩溶区水土保持工作的需求,提出笔者的3个展望:首先,推动学科交叉融合,引入并应用多种新技术和新方法深化岩溶区土壤侵蚀研究;其次,拓宽研究视野,运用多元化手段探究岩溶区土壤侵蚀在长时间尺度上的演变特征;最后,对现有土壤侵蚀模型进行优化升级,融入试验数据,以提高对未来土壤侵蚀趋势的预测能力.Soil erosion in karst area of Southwest China poses a severe threat to the regional ecological and environmental security and sustainable economic development. Since the latter half of the 20th century, extensive research has been conducted on soil erosion in this area, yielding significant achievements. Based on systematic analysis of the research progress, this paper elucidates the characteristics of soil erosion in the Karst area of Southwest China. Furthermore, this paper analyzes and summarizes the current research approaches, their current state, and inherent limitations across three distinct temporal scales, that are the short-term (<50 years), medium-term (<100 years), and long-term (>100 years) scales. To address the demands for soil and water conservation in Southwest China, this paper puts forward three prospects. Firstly, fostering interdisciplinary research by integrating novel technologies and methods to advance soil erosion studies in Karst areas. Secondly, expanding research horizons to explore long-term soil erosion history in Karst areas using diverse approaches. Lastly, refining existing soil erosion models with experimental data to enhance predictive accuracy for future trends.
