| 摘 要： | 使用新型遥感数据-“北京一号”小卫星数据,采用BP神经网络法对密云水库流域内的植被覆盖进行反演,并将结果与传统回归分析法和NDVI像元二分法进行比较。结果表明：在山区植被信息遥感反演算法中，神经网络方法以其对非线性过程的精确模拟而具有比传统算法更高的精度,尤其对于遥感反演算法难度较大的山区植被覆盖信息提取效果较好。

| Abstract: | Beijing-1 is a new type of earth observation satellite which is lunched by China.An Artificial Neural Network(ANN) method for vegetation cover retrieval with Beijing-1 in Miyun Reservoir basin has been developed in this paper,and then the result was compared with the traditional regression analysis method and the NDVI method for dimidiate pixel model.It demonstrates that for vegetation cover retrieval in mountainous areas,ANN has the advantage of precise simulation of non-linear transmission over traditiona... |
