The sugan lake basin is located in the inland arid region of northwestern China,in which groundwater is of great significance to human and ***,it is necessary to understand the chemical characteristics and quality of groundwater in the *** on samples collected from 35 groundwater wells in sugan lake basin,the spatial distribution characteristics of groundwater chemistry,main hydrogeochemical processes and groundwater quality have been discussed in this paper by using the multivariate statistics and hydrochemistry analysis *** results showed that the groundwater is weakly alkaline,and its total dissolved solid(TDS)and total hardness(TH) are high,with the average values of 1244.03 mg/L and 492.10 mg/L,*** types of groundwater are mainly HCO_3^--SO_4^(2-)-Ca^(2+)type in the runoff area and Cl^--SO_4^(2-)-Na^+type in the catchment *** weathering and ion exchange are the main controlling factors of regional groundwater chemistry,followed by evaporative crystallization,and human activities have less impact on *** spatial difference of groundwater quality is obvious,the water quality of the catchment area is not suitable for drinking,and the suitability for plant growth is also *** groundwater in the runoff area can be used for drinking,but the hardness is slightly higher,which is more suitable for ecological purpose.

Understanding controls on river planform changes can help to build predictive models for distributive fluvial systems,and then guide the oil and gas *** do this we have undertaken a detailed investigation of the modern Great Halten River distributive fluvial system from the sugan lake basin,Qinghai,*** aerial vehicle(UAV) photography,satellite remote sensing data and elemental analysis were used to determine differences in the sedimentary characteristics of the distributive fluvial *** the apex to the toe,the changes in the slope,river morphology,sedimentary characteristics and element content in different regions were determined and three facies belts:“proximal”,“medial” and “distal” were *** found that the sedimentary structure and elemental content characteristics of each facies differ *** compare the large-scale evolution of rivers from braided to meandering rivers,and the fine description of sedimentary characteristics in combination with each observation,we strengthen our overall understanding of the modern DFS from macro to micro *** the same time,we summarize the sedimentation model of the Great Halten River DFS,and our study provides a reference for establishing the sedimentary model in continental petroliferous basins.
