- Title:
- Study on Soil Organic Carbon and Its Oxidation Enzyme in Karst Area
- Keywords:
- oxidation organic carbon; soil enzyme; karst area
- 分类号:
- S153.62
- 摘要:
- 研究喀斯特地区不同土地利用方式下土壤的可氧化有机碳的含量以及碳转化酶的活性，结果表明：1/3 mol/L，1/6 mol/L，1/30 mol/L可氧化有机碳在不同的土地利用方式下含量的大小依次是乔木林>花椒林>荒地>耕地；蔗糖酶活性在7 a，10 a，13 a，14 a生花椒林中较高，其次乔木林，2 a生花椒林活性较低，荒地中蔗糖酶、多酚氧化酶活性最低。2 a生花椒林中蔗糖酶、过氧化氢酶活性最低。其余为耕地中酶活性最低。花椒林中大部分酶的活性介于荒地与耕地之间，并且通过相关性分析表明：三种可氧化有机碳，有机质、全氮与土壤酶活性（除过氧化氢酶外）之间存在显著或极显著的正相关关系。
- Abstract:
- The oxidation organic carbon content and soil enzyme activity were analyzed in different land use patterns. The results showed that: the oxidation organic carbon of 1/3 mol/L,1/6 mol/L,1/30 mol/L in different land use patterns performed arber forest>Zanthoxylum planispinum’s forest > wasteland > Arable land. The activity of sucrase in 7 a, 10 a, 13 a, 14 a was highest in the Zanthoxylum planispinum’s forest, the next one was arber forset. The activity of sucrase and polyphen oxidase were the lowest in the arable land. The activity of sucrase and catalase were the lowest in the 2 a Zanthoxylum planispinum’s forest. The most soil enzyme was on the mid of arable land and wasteland. And the correlation was analyzed. The results showed: the significantly or very significant positive correlation was performed between the oxidation organic carbon, organic matter, total nitrogen and the soil enzyme activity.
