| 摘 要： | 为探讨土壤健康的生物学指标，该文对北京八达岭地区不同植被类型0～5 cm土层的土壤酶活性及其与土壤肥力状况的相关性进行了研究. 结果表明:不同植被类型的土壤酶活性有显著的区别，其中除过氧化物酶外，糠椴林的土壤酶活性均属最高水平，而灌草丛所有酶活性都属最低水平；灌木丛中脲酶和碱性磷酸酶活性显著高于杂木林； 华北落叶松林的磷酸酶和过氧化氢酶活性均高于油松林. 相关分析表明，脲酶、酸性磷酸酶、碱性磷酸酶、过氧化氢酶与土壤肥力状况的相关性较好;总磷酸酶活性与土壤肥力状况的相关性高于单项磷酸酶； 多酚氧化酶和过氧化物酶与土壤肥力状况的相关性较差.

| Abstract: | In order to approach the biological indicators of soil health, the activity of soil enzymes and its relations with the soil fertility in 0-5 cm horizon under different vegetation types were studied. Results showed that the activity of soil enzymes was obviously different. Among the different vegetation types, the activity of soil enzymes under Tilia mandshurica forests was the highest except peroxidase, whereas that under shrub-grass was the lowest. The activity of soil urease and alkaline phosphate under shrub was higher than that under the mixed forests. Activity of soil catalase and phosphate under Larix principis-rupprechtii forests was higher than that under Pinus tabulaeformis. The relations between enzyme activity and soil fertility showed that urease, acid phosphate, alkaline phosphate and catalase were all had good correlations with soil fertility. Secondly, the correlation coefficient of the total phosphate was higher than the individual. Polyphenol oxidase and peroxidase were not related to soil fertility. |
