摘要
以TM影像、1:1万数字地形图以及其它辅助数据为基础,以土地利用类型、植被覆盖度以及坡度等作为影响因子,在遥感和GIS技术的支持下,对余江县洪湖乡的土壤侵蚀强度进行了快速分级评价实验。结果表明,该方法所获取的土壤侵蚀强度信息与实际情况比较吻合。
TM image, digital topographic maps on the scale of 1：10000, and other ancillary materials were used in this study. Land use type, vegetation cover rate and slope were selected as impact factors to make a rapid evaluation of soil erosion intensity in Honghu, Yujiang County, supported by remote sensing and GIS. As a result, the classification map of soil erosion intensity was obtained. On such a basis, the situation of soil erosion intensity in the study site was analyzed, and the results show that the soil erosion intensity information derived from the method in this paper is quite close to the real situation.
