黑河流域地下水电导率空间分异特征及影响因素研究
Spatial differentiation characteristics and impact factors of groundwater conductance in the Heihe River basin
摘要
Abstract
Heihe River is the second largest inland river basin in arid regions of northwest China.Study on groundwater conductance of the Heihe River basin has important significance in protecting its groundwater resource and reducing destruction of ecological environment. Characterization of spatial variation of groundwater conductance and its relation with maj or ions revealed that shallow and deep groundwater in the upper reaches showed low conductance values, lower than in the middle and lower reaches. Shallow groundwater in the middle reaches showed higher conductance than deep groundwater,but there was little difference between shallow and deep groundwaters in the lower reaches.Regionally,conductance of shallow groundwater in main stream of the middle reaches increased along the flow path.In the middle and lower reaches,shallow groundwater samples near the river channel had higher conductance than samples far away from the river channel.Conductance of shallow and deep groundwaters of the upper reaches and piedmont plain were lower,significantly lower than in the fine soil plain area of the middle reaches.In the lower reaches,deep groundwater conductance along the river channel from Langxin Mountain to Ej ina city was significantly different from areas from Juyan Lake to China-Mongolia border region.Relationship between groundwater conductance and maj or ions revealed that groundwater conductance in mountainous area of the upper reaches was mainly due to Na+ and Cl-,but mainly attributed to Na+,Cl- and SO2-4 in the middle and lower reaches. In addition,samples of deep groundwater in the middle reaches far away from the river channel and samples of shallow and deep groundwater near river channel in the lower reaches were also affected by agricultural irrigation activities.关键词
