摘要:
NDVI是区域土壤侵蚀评价的最佳植被因子.基于遥感影像TM数据提取了NDVI值并将其与土地利用信息同时集成于土壤侵蚀图的每个图斑,建立了包含多种因子的空间数据库.通过每个图斑林草地面积百分比和NDVI值的统计分析,建立了NDVI与植被盖度的线性关系.多重因子数据库和NDVI-植被盖度关系,可以为区域土壤侵蚀定量评价提供支持.
Abstract:
For modeling soil erosion at the regional scale,NDVI is extracted from TM images.NDVI and landuse information are integrated into each of the polygons of soil erosion map,by relating NDVI value to the ratio of forest and grass,relationship between NDVI and vegetation coverage was built.The model,NDVI-vegetation coverage,can provide support to develop regional soil erosion model.
