摘要：为了确定不同海拔毛竹林的土壤肥力状况,选择土壤理化性质、微生物性质和酶活性作为土壤肥力评价因子,运用灰色关联度分析方法定量分析毛竹林的土壤肥力,并进行综合排序。结果表明:5个海拔毛竹林土壤肥力关联度的大小依次为700 m>600 m>500 m>400 m>300 m。关联度与土壤化学性质、真菌和放线菌数量以及土壤淀粉酶、β-葡糖苷酶和多酚氧化酶呈正向相关关系。因此,土壤化学性质与土壤酶活性可以作为土壤肥力快速评价指标。
In order to determine the soil fertility of Moso bamboo forests at different altitudes in Dagang Mountain , soil physical and chemical properties , microbial properties and enzymatic activities were chosen as assessment indicators . Soil fertility was analyzed quantitatively by grey relational analysis , and ranked by correlation degrees comprehensively . The results showed that the order of soil fertility in Moso bamboo forests at different altitudes was 700 m〉600 m〉500 m〉400 m〉300 m.Correlation degree had a positive correlation with soil chemical properties , the number of bacteri-um, actinomycetes , activities of amylase ,β-glucosidase and polyphenol oxidase .Consequently , we concluded that soil chemical properties and soil enzymatic activities can be used as indicators for assessing soil fertility rapidly .
