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。

关键词: 固沙造林, 流动沙丘, 土壤酶活性

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

Key words: Afforested sand dune, Shifting sand dune, Soil enzyme activity
