Abstract: Closely hydraulic connection and frequent conversion relationship exist between river and groundwater. In recent decades, due to natural causes and human beings activity, the relationship drives to complexity, water cycle is varied, and series of negative effect of ecological environment are induced, which make the water resource and ecological problems sharp. The relationship and its evolution are one of the most important problems of the interaction between river and groundwater, and are parts of the basic research contents of maintaining mechanics of river and reproducible capability of groundwater. Based on types division about conversion relationship between river and groundwater, according to indoor test and field experiment data, incorporating geological and hydrogeological condition, the authors analyse the seepage characteristic of each type and the factors which affect the evolution of the relationship. On the basis of current study situation, the authors analyse the shortage existing in current field and related scientific problems needed to be resolved which provide scientific basis for quantitative simulation and evaluation of the evolutional relationship between river and groundwater.
