    摘要:

    对桉树林地土壤酶活性与土壤养分性质和林木生长关系的研究表明:桉树林地土壤酶活性同土壤养分之间存在一定的相关性,并且有一定的专性特性;林分蓄积量和生物量同土壤酶活性之间也存在一定相关;间种菠萝林地较之纯林地具有更适宜的酶活性;但以土壤酶活性作为桉树林地土壤肥力的评价指标,还须对其适宜范围作进一步探讨。

    Abstract:

    The relations among soil enzyme activities, soil nutrition content and stand growth in a eucalypt plantation were studied. The result is as follows: Soil enzyme activities are correlated with soil nutrition content fairly, and there is certain speciality in eucalypt plantation; the volume and biomass are correlated with soil enzyme activities fairly; soil enzyme activities in eucalypt stands with pineapple are more applicable than in those with no pineapple; but the applicable range must be further investigated before soil enzyme activities are used as appraisal indicators for soil fertility in eucalypt plantation.
