摘要
通过对武夷山9种林型土壤酶活性的研究表明:不同林型各种土壤酶活性呈现上层高下层低的层次性;不同林型各种土壤酶活性表现出差异性;不同林型各种土壤酶活性大多有明显的夏季高冬季低的季节性动态变化;不同林型各种土壤酶活性及土壤养分的季节性变化与林木生长高峰相吻合;不同林型各种土壤酶活性与土壤氮、磷、钾肥力呈显著正相关,故各种土壤酶活性水平可作为评价土壤肥力的指标。
By means of studies on the soil
enzyme activities of nine forest types in the Wuyi Moun-tain this paper reveals that various
soil enzyme activities of different forest types are high in the upper layer and low,in the lower
layer:they are different:most of them possess evident seasonal dynamic changes(i.e.high in
summer and low in winter):the seasonal changes of them and soil nutrients tally with the
growth peak of forest trees;they assume significantly positive correlation with the fertility of
nitrogen,phosphorus and potassium in the soils and so the various soil enzyme activity levels
can be as the indexes of evaluating soil fertility。
