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.
