摘要：借助地理信息系统软件ArcGIS空间分析平台,利用增强型专题绘图仪（ETM）遥感图像和地理空间数据库,定量分析了浙江省富阳市不同水土流失程度下的地理特征（坡度、坡向、高程、土地利用方式等）,揭示了研究区域土壤侵蚀与地理环境背景的空间关系。结果表明：水土流失的地理环境分异明显,94.57%的水土流失发生在500 m以下高度带;85.33%的水土流失集中在15°~35°的坡度上;57.23%的水土流失发生在南坡;49.40%的水土流失分布于黄泥土;76.85%的强度及其以上程度水土流失发生在园地;58.35%的水土流失发生在低山丘陵区。
This paper analyzed the geographical features of different soil erosion intensities such as gradient,slope direction,altitude and land utilization with the ETM remote sensing images and geographical spatial database by the platform of ArcGIS analysis,to reveal the spatial relationship between soil erosion and its geographical environmental background.The results showed that soil erosion had high selectivity of geographical factors.94.57% of soil erosion occurred in areas below the altitude of 500 m,85.33% in the areas with gradients between 15°-35°,and 57.23% in southern slopes,49.40% in areas with yellow soil;76.85% of high-intensity soil erosion were found in garden land and 58.35% in low mountains and hills.
