Calculation And Evaluation Of Groundwater Resources In Transboundary Aquifers Between China And Russia In The Jiebuxun Plain

The Sino Russian transboundary aquifer in the Jiebuxun plain is a shared aquifer between China and Russia.It is named after the Heilongjiang River,the Jieya River,the Bulieya River and the Xun River.Previously,China and Russia did not assess the groundwater resources of the aquifer in the same way.Each country used its own standards and procedures to assess the groundwater resources of its own part of the aquifer.There are different views on the scope of aquifers,and there is no consensus.Only a few aquifers in China have been allocated for groundwater resources,and no similar research results have been found in Russia.Therefore,in order to effectively assess the groundwater resources of the aquifer,it is necessary to assess and determine the zoning of the aquifer and its groundwater resources.According to the analysis of the physical geography and socio-economic characteristics of the Sino Russian transboundary aquifers in the Jiebuxun Plain,and the analysis of the principles and methods of the zoning of the study area,the scope of the aquifer is evaluated and determined from the perspective of the whole aquifer,and the groundwater resource zoning analysis and evaluation are carried out in combination with the relevant maps.The results show that the Sino Russian transboundary aquifer in Jiebuxun plain is located in the middle of Heilongjiang Basin,with a total area of 11.82×10~4km~2,including 1.59×10~4 km~2 in China,10.23×10~4 km~2 in Russia;Based on the full collection and sorting of hydrological and meteorological,geological background and other information of the basin,the study area is zoned and analyzed by using the dominant indicator method and overlapping method,According to hydrogeological conditions,it can be divided into 3 groundwater evaluation zones,8 surface water zones according to surface water conditions,and 24 administrative zones according to administrative zones.After coupling,73 coupling zones are obtained;Deduct the internal repeated calculation of groundwater 9.96×10~8m~3,the annual average groundwater resources are about143.34×10~8m~3,including 19.67×10~8m~3 in China,123.67×10~8m~3 in Russia.
