    摘要:

    3S技术是集遥感(RS)、地理信息系统(GlS)和全球卫星定位系统(GPS)于一体的新兴技术。以影响土壤侵蚀最为显著的植被覆盖度、坡度和土地利用状况3大因素,按照土壤侵蚀分类分级标准的指标,应用3S技术对厦门市的土壤侵蚀状况进行快速调查,及时掌握监测区域的土壤侵蚀现状,实现对土壤侵蚀的监测和评价,同时探讨了土壤侵蚀分布的规律和成因,为今后厦门市水土保持规划和土壤侵蚀防治工作提供科学依据。

    Abstract:

    The 3S technology,an integrated technology with remote sensing,GPS and GIS,is a new high-tech means.The 3S technology was used for the investigation of soil erosion in Xiamen,and the studying method may be outlined as follows.First,the author obtained the slope data by DEM,the vegetation cover rate by interpretation of SPOT5 images,and the land use data by the digital land use map.Second,the author understood the situation of soil erosion by following the standards for soil erosion classification and gradation and using the overlaying function of GIS.Third,basing on the situation of soil erosion in the region,the author analyzed the changes and causes of soil erosion distribution.The result provides a scientific base for soil and water conservation planning and soil erosion control.
