摘要

土壤酶活性的高低可以直接或间接反映土壤肥力和土壤健康程度。研究选取烟台市黄务镇破坏山体周边7种植被恢复模式

测定土壤脲酶、多酚氧化酶、过氧化物酶、过氧化氢酶活性及土壤理化性质和细菌、真菌、放线菌数量。目的是探讨不同植被恢复模式对土壤酶活性的影响机制

为合理恢复植被提供参考依据。结果表明:不同植被恢复模式的土壤酶活性表现为0-10cm土层高于10-20cm土层;对土壤酶活性的改善作用为混交林>纯林>灌草丛

人工植被恢复模式中以黑松麻栎混交林最优;土壤酶活性具有显著差异(P<0.05)

其中以脲酶差异最为显著

与自然恢复的灌草丛相比

0-10cm土层脲酶活性增加44.71%～231.79%

10-20cm土层脲酶活性增加163.00%～959.00%;4种酶的活性均与有机质有密切的关系

提高土壤有机质的含量可以增强酶活性;脲酶、过氧化物酶、过氧化氢酶之间存在密切关系

并且三者与微生物含量的相关性也达到显著水平(P<0.05)

其中脲酶和多酚氧化酶可以作为破坏山体土壤质量评价的指标。破坏山体植被恢复过程中应以营造针阔混交林为主。

Abstract

The soil enzyme activities can reflect the soil fertility and healthy status directly or indirectly.Soil samples were collected from 7 revegetations in Huangwu county

Yantai city

Shandong province

and their activities of urease

peroxidase

catalase and polyphenol oxidase

soil physicochemical properties

number of soil bacteria

actinomycete and fungus were measured.Its aim is to analyze the impact mechnism of revegetation types on the soil enzyme activities to provide scientific references for reasonable veget...
