动态综合层次判别分析方法──以水土流失强度综合分析为例

随着遥感技术的发展，可获取的遥感信息越来越丰富，各种分类算法也层出不穷，然而在分类精度上却始终无法突破遥感数据本身的局限，而且不同的方法在判识的结果上往往有很大的不同。本文认为不同遥感信息、不同的判别分析方法，对不同的对象在不同的地表组合条件下其判别的能力是不同的，只有综合地运用这些不同的方法才可能在现有遥感资料的能力下提高分类精度。本文提出一种动态综合层次判别分析算法可将多种并行的分类算法综合在一起，取长补短，提高最后分类精度。通过在浙江省新昌县某地进行水土流失强度分析试验，取得了良好的效果。

Dyoamic Compreheasive Hierarchy Discriminatory Analysis Method: A Case Stady on Soil Erosion Intensity Analysis

There an a lot of different types of remotely sensed information sources, and various information abstraction methods by the development of remote sensing technique. But the improvement of the analysis accuracy is difficult because of the limit of remotely sensed data. Dynamic Comprehensive Hierachy Discriminatory Analysis Method proposed in this paper can concentnte the advantage of various information abstrction methods to improve the final accuracy in remote sensing application. An application case study on soil erosion intensity analysis for Xinchang county, Zhejiang Province shows a very good effect.
