| 摘 要： | 流动沙丘造林固沙后，土壤酶活性发生了变化，不同造林树种和不同造林时间的沙丘土壤酶活性均不相同。沙丘结皮层的土壤酶活性明显比下层沙土强，土壤微生物的泪长与土壤酶活性变化基本相似。

| Abstract: | The soil enzyme activity in afforested Satnd dunes is variable compared with shifting sanddunes. It varied with the forest species and ages.The soil enzyme activity is higher in crust layers ofsand dunes than in the subsoil layers.The intensity of soil enzyme activity is related to the growthcondition of microorganism. |
