Abstract:: Through the spatial factor and experimental data analysis of oasis soil salinization of Kaidu River Basin, taking the downstream oasis as an example, using application of grey correlation degree analysis of each factor in size relative influence of land salinization process, six impact factors were selected. The results showed that the natural and anthropic factors commonly influenced soil salinization. Soil moisture correlation in 0—10 cm layer between the amount of salt and influencing factors ranked in the order of groundwater depth > recent drainage distance > elevation > recent irrigation canals distance > recent lake distance > mineralization of groundwater; for 10—30 cm layer, groundwater depth > recent lake distance > recent drainage distance > elevation > recent irrigation canals distance > mineralization of groundwater; for 30—50 cm, recent irrigation distance > groundwater depth > recent drainage distance > mineralization of groundwater > recent lake distance > elevation. Each one in each soil depth on influence factors is different, soil salinization of land in the area is complex, its governance work required a comprehensive consideration of all factors.
