- 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0~60 cm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）。
- Abstract:
- 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).
