exhibits distinct salt accumulation processes in different regions.This study aimed at providing scientific basis for the improvement of ecological environment of the Luohuiqu irrigation district by exploring the variations of groundwater salinity.Periodical variations of groundwater level and electrical conductivity has been analyzed at well 76# using Morlet analysis.It is shown that the two variables were significantly closely correlated.The period of groundwater level on small scale was similar to that of electrical conductivity
but approximately two times longer on large scale
with a reverse phase.The electrical conductivity background of the groundwater was relatively high
because of the large amount of soluble salt layers found in this area.Due to indirect water supply from precipitation
electrical conductivity values fluctuated with groundwater levels within a certain range.
