摘  要：
在浙江省凤阳山自然保护区选取海拔相近的6个典型林分类型(常绿阔叶林、针叶林、针阔混交林、杉木林、毛竹林以及柳杉林),在其林下采集土壤样品,分析了脲酶、蔗糖酶、酸性磷酸酶和过氧化氢酶、蛋白酶5种主要土壤酶活性的变化。结果表明,在6个林分类型中,常绿阔叶林土壤脲酶、过氧化氢酶、酸性磷酸酶活性均较高;柳杉林分土壤蔗糖酶活性较高;而针叶林则表现出土壤蛋白酶活性最高;杉木林则表现出土壤脲酶、蔗糖酶活性较低;土壤酶活性具有明显的垂直分层分布,土层越深,土壤酶活性越低;同时该地区土壤酶活性与土壤理化性质指标相关性较高,尤其是pH值和有机质含量与土壤酶活性关系最为密切。

摘  要：
The activity of 5kinds of soil enzymes(urease,protease,acid phosphatase and catalase,sucrase) were studied in six typical forest types(evergreen broad-leaved forest and coniferous forest,conifer/broadleaved mixed forests,chinese fir forest,Bamboo forest and Cryptomeriafortune forest)at the similar altitude in Fengyang Mountain nature reserve of Zhejiang Province.The results showed that evergreen broadleaved forest soil urease and catalase,acid phosphatase activities were higher;Cryptomeriafortune forest soil invertase activity was higher;And coniferous forest showed the highest soil protease activity.In contrast,the chinese fir forest soil′s urease,invertase activity was low;Soil enzyme activity had obvious vertical stratification distribution,the soil was deeper and the enzyme activity was lower;At the same time,correlation analysis showed that the soil enzyme activity and soil physical and chemical properties index correlation was higher,especially the pH value,organic matter content and soil enzyme activity in most close relations.
