内容提要：
This piece of scientific work is of vital importance for those who want to understand and further investigate the temporal variation the chemical characteristics of Lake Ziway - a fresh water lake in the Ethiopian Rift-Valley lakes system. It is devoted to the discussion of variations over years in the salinity and sodicity of the lake. The salinity and sodicity trends are probed in relation to the annual and seasonal variation in the hydro-meteorological factors that determine the chemical characteristics of the lake. It succinctly depicts the causal interrelationship between the temporal level of salinity and sodicity of the lake and the hydro-meteorological factors that govern the lake's chemical characteristics. It summarizes varied historical hydrological, meteorological and hydro-chemical data from previous records and researches to lucidly presents their implication on the temporal variation in the salinity and sodicity of the lake. It finally suggests some recommendations as to how the freshwater nature of the lake can be sustained.
