武夷山不同海拔典型植被带土壤酶活性特征
Soil enzyme activities in typical vegetation zones along an altitude gradient in Wuyi Mountains.
摘要
Abstract
This paper measured the activities of soil urease, sucrase, acid phosphatase, and cat-alase in four typical vegetation zones, I e. , evergreen broadleaf forest (EBF), coniferous forest (CF) , sub-alpine dwarf forest ( SDF) , and alpine meadow { AM) , along an altitude gradient in the Natural Reserve of the Wuyi Mountains in Fujian Province of East China. In the four zones, there were no significant seasonal variations in the activities of test enzymes except acid phosphatase, whose activity was significantly higher in autumn than in any other seasons. The activities of test enzymes differed significantly with altitude, but less affected by the interaction of season and altitude. The enzyme activities showed an overall increasing trend with the altitude, being significantly higher in AM zone than in EBF and CF, and decreased with soil depth. The soil urease activity in the four zones was in the range of 1. 28-3. 87 mg · g-1 · 24 h-1, and in the order of AM>EBF>SDF>CF; soil sucrase activities was in the range of 36. 18-244. 08 mg · g-1 · 24 h-1, and in the order of AM>CF>EBF>SDF; acid phosphatase and catalase activities were in the ranges of 0. 18-0. 62 mg · g-1 · 2 h-4 and 1.78-1. 98 ml · g-1 · 20 min-1 , respectively, and in the order of AM>CF>SDF>EBF. The soil enzyme activities were significantly positively correlated with soil total organic carbon and total nitrogen, and had complicated correlations with soil temperature, moisture, and pH.关键词
