摘　　要：土壤侵蚀已成为全球环境领域关注的焦点,严重威胁生态平衡与区域可持续发展,它不仅导致土壤质量下降,还影响土壤提供的生态系统服务。为此,本研究以苏州市吴江区为例,利用中国土壤流失方程(CSLE)模型,结合遥感技术与空间分析方法,深入探究了水土流失的影响因素,并构建了水土流失敏感性评价指标体系。研究结果显示,吴江区的土壤侵蚀主要集中在平原沙土区域,其中水力侵蚀尤为显著。尽管宏观层面水土流失程度较低,但实际土壤流失量高达897.92t。这表明,必须加强水土保持监管工作并采取有效措施进行治理。这一研究不仅为吴江区的水土保持工作提供了科学依据,也为其他类似地区的环境保护与水资源管理提供了有益借鉴。通过遥感技术与空间分析方法能够更准确、全面地评估地区的水土流失状况,为制定有效的水土保持策略提供有力支持。Soil erosion has become a global focus in environmental concerns,posing a serious threat to ecological balance and regional sustainable development.It not only leads to a decline in soil quality,but also affects the ecosystem services provided by soil.Therefore,this study takes Wujiang District in Suzhou as an example,utilizes the Chinese Soil Loss Equation(CSLE)model,combines remote sensing technology and spatial analysis methods,deeply explores the influencing factors of soil erosion,and constructs a soil erosion sensitivity evaluation index system.The research results show that soil erosion in Wujiang District is mainly concentrated in the plain sandy soil region,with water erosion being particularly significant.Although the degree of soil erosion is relatively low at the macro level,the actual amount of soil loss is as high as 897.92 t.This indicates that we must strengthen supervision of soil and water conservation and take effective measures to manage it.This study not only provides scientific evidence for soil and water conservation work in Wujiang District,but also provides useful references for environmental protection and water resources management in other similar regions.The application of remote sensing technology and spatial analysis methods can more accurately and comprehensively evaluate the status of soil erosion in the region,providing strong support for the development of effective soil and water conservation strategies.
