摘  要:
选择伊犁河谷为研究区,采集不同土地覆被下的土壤样品,研究林地、耕地、园地、草地等4种不同土地覆被对土壤酶活性的影响。结果表明:不同土地覆被下,在0~60cm的土壤深度中,土壤蔗糖酶、脲酶与过氧化氢酶这3种酶的活性随着土层深度增加都呈现出降低趋势,土壤蔗糖酶、脲酶、过氧化氢酶均表现为林地>耕地>园地>草地。通过不同土地覆被土壤酶活性与养分相关性分析,得出林地的脲酶活性与其有机质有极显著相关关系(P<0.01);耕地和园地中的3种酶活性都与其有机质有极显著相关性(P<0.01);草地中的蔗糖酶的活性与其养分有极显著相关性(P<0.01)。

摘  要:
Collecting soil samples under different land cover in Yili valley area.Effect of woodland,farmland,orchard,meadow on soil enzyme activities was researched.The results showed that soil depth of 0-60 cm under different land cover,the soil invertase,urease and catalase activity exhibited increasing with soil depth,but they had emerged decreasing trend.Soil invertase,unease,catalase all showed woodland>farmland>garden>lawn.Through correlation analysis of soil enzyme activity and nutrient in different land cover,the urease activity of woodland had a significant correlation with its organic matter(P<0.01);there kinds activity of enzyme in farmland and parkland had a significant correlation with its organic matter(P<0.01);the invertase activity of the grass had a significant correlation with its nutrients(P<0.01).
