Based on dynastic period division and AMS C 14 dating performed on the sedimentary layers at Zhongba and Yuxi sites, and also the analysis of Na, Ca and Mg of 201 sedimentary samples from Zhongba site and that of Ca and Na in 47 sedimentary samples from Yuxi by using an inductively coupled plasma-mass spectrometry (ICP), the AA. found that there were 35 time periods when the contents of Ca and Na were reversely correlated : 21 time periods with the peak values of Ca indicating 21 prosperous periods of ancient salt production and 14 time periods with the peak values of Na indicating 14 declined periods of salt production at Zhongba site. All the results indicate indicate that there is a reverse relationship obviously between the contents of Na and Ca in sediments at Zhongba site for ancient salt production, which can be used to reveal the process of rise and decline of ancient salt industry at Zhongba site
