针对青海湖周边流动沙丘的治理，采用化学固沙材料W—OH，进行了坡面直接喷涂、开沟喷涂和设对照的治沙试验，重点对W—OH的入渗深度、不同处理喷涂后的植被数量、地温及含水量进行了统计分析。结果表明：在同一播种量的条件下，开沟喷涂处理内植被数量最多，明显高于坡面喷涂处理和对照；在2cm土层内，3种处理其地温无显著差异，在12、20cm土层内，喷涂W—OH的处理显著高于对照（P〈0．05），且保水效果好。

Experiments were conducted using sand fixing material W-OH by spraying directly on the dune slope surface, furrow surface. Check was set for comparing. The soil of water content, infiltration depth, temperature and the number of plant were measured. The results show the W-OH ＋ furrow method is the best in water conservation and the soil temperature. Spraying W-OH ＋ furrow processing resulted in higher vegetation than the other two treatments. No belowground temperature difference was detected in depth of 2 cm. Soil temperature and moisture were significantly higher than those of check in depth of 12 cm and 20 cm, and which were conducive to the vegetation root system layer to make full use of water.
