The surviveand development of CA law system can not leave the certain material life condition andcertain production pattern, so, different CA ecology reflects different economy foundation: Traditional accusatorial action based on the ethics order is co-related with the originaleconomy ecology; Traditional inquisitorial action based on the administrative order isco-related with developed cultural economy ecology. The difference of western economyecology and eastern economy ecology leads to the different genes though them faced thesame traditional inquisitorial action. The modern CA based on the law order lies on thedeveloped commercial economy, the mature market economy and modern citizen societybring about the modern CA ecology whose task is resolve the action contradiction withration.

Taking for example the salt rhythms of the Qianjiang Formation in the Qianjiang Sag of the Jianghan Basin (which is a typical Paleogene saline lacustrine basin in eastern China), through a detailed study on cores, the authors have determined for the first time the Ⅳ-order salt rhythm based on Ⅰ-,Ⅱ-and Ⅲ-order salt rhythms which were determined previously and got to know that the sedimentary process following the sequence of desalinizing→salinizing and crystallization of salt minerals from halite rock→(mud-bearing) glauberite rock→dolomite-bearing mudstone (mud-bearing doloston)→mudstone→doloston→glauberite rock→halite rock. The authors also analyzed the Ⅳ-order salt rhythm and the correspondence between its sedimentary records and the fluctuation of the palaeosalinity of waters and the short-scale (0.05~1.0 ka duration) change of dry-moist palaeoclimate.
