摘要
基于GIS技术对秦巴山区的宁强县土壤侵蚀特征进行研究。通过解译遥感影像得到研究区的土地利用现状和植被覆盖等数据,使用GIS技术对地形图数据处理得到DEM等数据,并用因子法计算研究区的土壤侵蚀模数,最终生成该区的土壤侵蚀模数图。研究结论可为该地区水土保持与土壤侵蚀防治提供科学依据。
Soil erosion characteristics in Ningqiang County of Qinba mountainous area are studied based on the GIS in the paper.We obtained the data about land used and vegetation covered by interpreting the remote sensing image.And based on GIS technology,After processing of the topographic map data,the DEM and other data are achieved.The article also calculated the soil erosion modulus by the factor method and finally formed its modulus map.The studies conclude which can provide the scientific basis for soil and water conservation together with the soil erosion control.
