摘要：以沙珠玉治沙试验林场内人工植被恢复的长期定位监测为基础,通过分析30 a生的6个植被类型区（青杨、柠条、乌柳、沙棘、柽柳、赖草）以及2个对照区（农田、流动沙区）0~30 cm土壤机械组成、p H值、有机质及主要养分等理化性质指标,明确了高寒沙区不同植被类型对土壤改良的效果差异。结果表明：（1）各类型区在植被恢复30 a后,土壤质地得到极大改良,土壤养分含量显著提高（P〈0.05）,但表层土壤的p H变异性较小,0~5 cm表层土壤的恢复效果明显好于5~30 cm层;（2）植被对土壤改良顺序为柠条〉青杨〉沙棘〉赖草〉乌柳〉柽柳;（3）柠条和沙棘林适宜在高寒沙区推广种植,并且可以采取适当抚育管理措施,以实现高寒沙区林场的可持续发展。
This study based on the vegetation restoration of long term monitoring experimental in sandy field forest at Shazhuyu, a village of Alpine Sandy Land. This study selected 6 vegetation plots（Populus, Caragana, Salix,Hippophae, Tamarix, Leymus） and two control plots（farmland, flowing sand land）, and analyzed soil texture, p H, soil organic matter and major nutrients properties at the soil depth of 0- 30 cm. The different effects of different vegetation types on soil improvement were clearly in Alpine Sandy Land. The results showed that：（1） After 30 years of various vegetation restoration, soil texture had been greatly improved, soil nutrients content increased significantly（P 〈0.05）, but the variability of soil p H was very little at the soil surface, the recovery was significantly better at 0- 5 cm soil layer than at the 5 ~ 30 cm soil layer, the nutrient mainly accumulated on the top soil layer;（2） The effect of vegetation on soil improvement decreased as follow： Caragana 〉 Populus 〉 Hippophae 〉 Leymus 〉 Salix 〉 Tamarix;（3）Caragana and Hippophae was more suitable for planting in Alpine Sandy Land, and it could take appropriately forestry management measures to achieve sustainable development in this area.
