                   Abstract:The exchange of water quantity between surface water and groundwater is a complex process that
                   is influenced by topographic factors, hydrologic factors and hydrogeologic factors. This article focused on
                   the analysis of a representative district of the Sanjiang Plain with four rivers as the research area bound⁃
                   ary: Songhuajiang, Heilongjiang, Naolihe and Wusulijiang rivers. The spatial-temporal variation of water
                   quantity exchange between river and groundwater in representative river sections of this region was investigat⁃
                   ed based on field hydrogeological investigations and analysis of the spatial distribution of river and ground⁃
                   water level dynamics from 2000 to 2018. The findings revealed that there is a strong hydraulic connection
                   between surface water and groundwater at representative river sections in the Sanjiang plain,which is signif⁃
                   icantly or highly correlated in more than 50% of the years during the study period. The Fujin section of
                   Songhuajiang River had the strongest correlation whilst Caijuzi section of Naolihe River and Haiqing section
                   of Wusulijiang River had a correlation between Fujin section of Songhuajiang River and Qindeli section of
                   Heilongjiang River. The weakest correlation was observed at the Qindeli section of Heilongjiang River. On a
                   perennial scale, the Caijuzi section of Naolihe River is ground water recharged by surface water, whereas
                   the Fujin section, the Haiqing section and the Qindeli section, of Songhuajiang River, Wusulijiang River
                   and Heilongjiang River respectively are all surface water recharged by groundwater. The perennial average
                   water quantity exchange per unit width of the river and groundwater in Fujin section of Songhuajiang River

                   is 10 (m /d·m), and Haiqing section of Wusulijiang River is 10 (m /d·m) The correlation coefficient
                                                                                 .
                   and the magnitude of water quantity exchange per unit width of the river and groundwater had a positive re⁃
                   lationship, the bigger the correlation coefficient value, the higher the water quantity exchange per unit
                   width, and the results of MK trend test show that the water quantity exchange between surface water and
                   groundwater in representative river sections has a decreasing trend,the trend is significant in Haiqing sec⁃
                   tion of Wusulijiang River, Fujin section of Songhuajiang River has the least decreasing trend. The water
                   quantity exchange of surface water and groundwater in the Fujin section of Songhuajiang River is strongly
                   dominated by annual and interannual fluctuation and only June showed a significant decreasing trend on in⁃
                   terannual scale,which does not constitute the significant annual decreasing trend,therefore the water quan⁃
                   tity exchange relation changes frequently wish a weak regularity. The Qindeli section of Heilongjiang River
                   is dominated by annual and interannual fluctuation,comparable to the Songhuajiang River,though to a less⁃
                   er extent,there is no significant interannual decreasing trend thus it does not constitute the significant an⁃
                   nual decreasing trend. The interannual fluctuation dominate the Caijuzi section of Naolihe River and there
                   was a significant decreasing trend from January to May,but it does not increase the fluctuation in interan⁃
                   nual scale and not constitute the significant annual decreasing trend. The Haiqing section of Wusulijiang
                   River is mainly dominated by annual fluctuation, the significant decreasing trend from June to September
                   and December increase the fluctuation in interannual scale and constitute the significant annual decreasing
                   trend. The findings of this study can serve as a scientific basis for the evaluation of water resources in the
                   typical district of Sanjiang Plain,as well as a theoretical reference for the scientific development and utili⁃
                   zation of water resources in this region.
