中文摘要	小叶锦鸡儿(Calpharaganalpha microphylla)和差不嘎蒿(Artemisialpha halodendron)是科尔沁沙地典型的固沙灌木,它们在退化沙地的恢复过程中起着重要的作用。本研究对这两种灌木林地表层土壤理化性质和酶活性进行了比较。结果表明:小叶锦鸡儿比差不嘎蒿对沙丘土壤理化性质和酶活性的改善作用较大。其中,小叶锦鸡儿林地土壤黏粉粒含量比差不嘎蒿高3倍左右,土壤含水量是差不嘎蒿的1. 31倍,土壤有机碳和全氮分别是差不嘎蒿的1. 35和1. 36倍,土壤过氧化物酶和脲酶活性分别是差不嘎蒿林地土壤的2和3倍。科尔沁沙地流动沙丘中种植小叶锦鸡儿和差不嘎蒿后,两种灌木均能改善沙丘土壤理化性质和酶活性,但是其改善能力存在一定差异,总体来说,在退化沙地土壤肥力和生物活性的恢复方面,小叶锦鸡儿的优势高于差不嘎蒿。
英文摘要	Caragana microphylla and Artemisia halodendron are two typical shrubs for stabilization of sand dunes, and play an important role in combating desertification in the Horqin Sandy Land. We studied the differences of soil physicochemical properties and enzyme activities between C. microphylla and A. halodendron dominating shrub lands. The result showed that C. microphylla is better to improve soil physicochemical properties and enzyme activities in sand dunes than A. halodendron. Clay and silt content is 3 times higher in C. microphylla shrub land than that in A. halodendron shrub land; soil water content is 1. 31 times more in C. microphylla than that in A. halodendron ; soil organic carbon and total nitrogen is 1.35 and 1.36 time in C. microphylla of that in A. halodendron, respectively ; soil enzyme (peroxidase and urease) activity is significantly higher (twice and triple) in C. microphylla than that in A. halodendron. After years of planting C. microphylla and A. halodendron in mobile dunes, both of the shrub species could improve soil fertility and enzyme activity, and better in C. microphylla shrub land than that in A. halodendron shrub land.
