研究基于TM遥感影像，运用多种方法针对典型内陆淡水湿地的水体信息进行了提取实验，通过对实验结果的分析得出：在面积的准确性、提取的准确度以及视觉效果3种指标下，光谱分类法较其它方法效果要好，其次为单波段阈值分析法与植被指数法，较差的是多波段谱间关系法与水体指数法；影响提取效果的主要原因是湿地水体提取不够完全，这是由影像的分辨率及湿地特殊的水文条件所造成的，采用像元分解及多源遥感数据融合技术将成为提高水体提取精度的重要手段。

PCA is not only used as feature extracting method (where process variables are subjected to multivariate normal distribution), but also as a tool for dimension reduction; BSA is used to extract independent features or process blind source signals from process information in information theory sense, which is more effective than PCA in describing the process.

主元分析方法不仅作为一种过程特征的提取方法（在过程信息服从多元正态分布的情况下），而且也作为一种过程数据降维的主要工具（在过程盲源信号提取的情况下）；盲源信号分析是从信息论的角度，从过程信息中提取出尽可能独立的过程特征信号或过程原始信源信号，它具有比主元分析更好的刻画过程运行特征的性能。

By above research, the following results are obtained.(1)The extracting module of aero-radioactive thematic information is integrated with ENVI, the remote sensing image processing software;(2) Based on the IDL, the computer program modules extracting following uranium thematic information have been developed, including initial uranium contents, active uranium contents, uranium migration coefficient, uranium information strengthen, uranium D-value and variance Ratio etc, al. Some of kalium special information extracting modules are also developed;(3)Based on the IDL, the aero-radioactivity information multi-parameter focus analysis module is developed;(4) It is proposed that a lots of phenomenon of uranium immigrating exist in Keping-Kuche are in the Neocene period. Because of the uranium pre-enrichment, the areas with high uranium content were formed in Neozoic and Quaternary. The above migration uranium are also the abundant source for uranium ore-forming in favorable strata of Mesozoic and Cenozoic system;(5)There are obvious uranium immigrating and enrichment in Eastern Portion of Keping Block Uplift, Yinate-Laolongjiang, and Qidaoban-KuChe.
