天台山不同林型土壤酶活性与土壤微生物、呼吸速率以及土壤理化特性关系研究

Study on the relationship among enzymes activities, microorganism, respiration rate and physico-chemical properties of soil under different forests of Tiantai mountain

天台山8种不同林型土壤环境酶活性的模糊数学分析表明,不同土壤环境总体酶活性水平的相似优先比顺序为:云锦杜鹃土壤>黄山松林土壤>茶园土壤>竹林土壤>金钱松林土壤>日本花柏林土壤>柳杉林土壤>七子花林土壤。不同酶之间以及酶与土壤环境因子之间存在着不同程度的相关关系。因子分析揭示了控制天台山不同土壤因素综合作用的主要因子为:土壤7种酶、土壤微生物数量、土壤呼吸速率和土壤总有机质。

The Fuzzy mathematic analysis of soil enzyme activities from 8 kinds of forest in Tiantai mountain indicate that the similar sequence of the net level of enzymatic activities from the different soil environments was: Rhododendron fortunei soil>Pinus taiwanensis soil>Tea plantation soil>Bamboo soil>Pseudolarix amabilis soil>Chamaecyparis pisifera soil>Cryptomeria fortunei soil >Heptacodium miconioides soil. There existed different relationships among the enzymes and between enzymes and soil environmental factors. The Factor analysis revealed the important factors governing the synthetic effect of soils. These important factors were 7 kinds of soil enzyme, soil microbial numbers, soil net respiration rate and soil gross organic matter.
