摘 要：
The neutron activation method is firstly used to determine the geo-chemistry background value of surface water in southern Xingjing. Seven water samples are collected from Keriya River,of which,thirty element contents are determined. The results show that:1. The geo-chemistry background value of surface water in arid area is greater than that in tropical and subtropical area of southern China,the former is normally n. 0. 001-n. 10~7p. p. b,the later n. 0. 0001-n. 10~5p. p. b2. The geo-chemistry element contents of surface water in arid area result from geo-endogenic force and geoexogenic force. The later plays an important role in the Keriya River.3. The geo-chemistry backgroud value of water in lake is greater than that in river.In conclusion,the geo-chemistry background values of surface water in arid area have deep relationship with regional climate,hydrology and geo-chemistry composition of rocks.
