Assessment of Vegetation Coverage Factor in Soil Erosion Model Based on ASTER Image Interpretation
摘要/Abstract
摘要：
针对土壤流失方程中植被覆盖度遥感估计存在的方法不确定问题,利用ASTER影像数据,使用植被指数及混合像元线性分解方法,结合地面调查数据,对土壤流失方程中植被因子做了进一步的研究分析,改进了利用混合像元分解定量估计土壤流失方程植被覆盖因子的方法.
Abstract：
Experiment s in Aibi lake area were made in order to compare the difference in soil erosion model between vegetation index and vegetation coverage obtained by linear spect ral unmixing. The results of the experiment indicate that vegetation coverage is more suitable for soil erosion model.
