Abstract:: This study selected straw sand-barriers in Qinghai Lake areas, to study desertification combating measures how to influence sandy soil, measuring soil water by drying method and saturated hydraulic conductivity by tension infiltration. The preliminary results were obtained: in Ketu area, soil water content of the straw sand-barriers of semi-mobile dune, the mobile dune, the interdune, the fenced area, and the straw sand-barriers in the bottom of slope, the middle of windward and the bottom of slope of the east of Lake all first increased nearly, then it showed the reducing trend. The saturated hydraulic conductivity in Ketu area, the semi-mobile dune>the interdune>the straw sand-barriers in the bottom of slope>the fenced area, and in the east of Lake, the middle of windward was higher than the bottom of slope. The saturated hydraulic conductivity was related with the sand soil particle, soil water, vegetation cover and soil crust.
