中文摘要	对阿拉善荒漠草地恢复初期（1998～200l）植被特征和土壤养分的变化进行了研究。结果表明：草地恢过程中，植被的盖度和生物量比封育前分别增加272％～536％和44．39％～305．3％。植被的恢复使土壤理化性质发生了变化，与封育前相比土壤中有机质、全N、速效K以及细砂、特别细砂和粘粒含量显著增加；速效N、速效P降低。土壤有机质、全N和全P的含量与土壤中＜0．05mm颗粒和速效K含量呈极显著正相关，并且前三者之也呈极显著正相关（P＜0．01）。
英文摘要	In this paper, vegetation change and soil nutrition in the early period of restoration of desert grassland in Alxa were studied. The results showed that vegetation coverage and hiomass of enclosed desert grassland increased by 272% -536% and 44. 39% -305. 5% respectively compared to those of unenclosed desert grassland under the similar environments. Vegetation restoration also resulted in the changes of soil physicochemistry properties including the significant increase in contents of organic matter, total nitrogen, available potassium, fine sand, very fine sand and clay, and the decrease in available nitrogen, phosphorus. Significantly, positive correlations were found between soil contents of organic matter, total N, total P and <0. 05 mm clay particle, available K, and between contents of organic matter, total N and total P.
