摘　　要：在3S技术的支持下,利用遥感影像、水土保持观测数据对水土保持现状进行监测,通过对遥感数据和专题数据进行综合分析,得出结论泸桥镇大部分土地主要以中度侵蚀为主,少量的微度、轻度和强度侵蚀,为水土保持信息发布、水土保持规划、治理措施实施等提供科学的依据。With the support of 3S technology,remote sensing images and soil and water conservation observation data are used to monitor the current situation of soil and water conservation.Through the comprehensive analysis of remote sensing data and thematic data,it is concluded that most of the land in Luqiao Town is mainly moderate erosion,and a small amount of slight,mild and intense erosion,which provides scientific basis for the release of soil and water conservation information,soil and water conservation planning and the implementation of governance measures.
