摘要:
利用空间序列代替时间序列的方法,研究了浙江天台山常绿阔叶林次生演替系列群落土壤微生物生物量和土壤酶活性变化。结果表明,从灌草丛到常绿阔叶林的不同演替系列群落土壤的有机质、总N、总P含量总体呈逐渐升高的趋势。灌草丛微生物生物量最低,微生物生物量C是从针叶林到常绿阔叶林阶段明显增加,但微生物生物量N却是针阔混交林>常绿阔叶林>针叶林。磷酸酶、脲酶与βD葡萄糖苷酶活性均以灌草丛土壤最低;在其他3个演替系列群落土壤中,脲酶和βD葡萄糖苷酶活性大小是常绿阔叶林>针阔混交林>针叶林,而酸性磷酸酶的活性大小是常绿阔叶林>针叶林>针阔混交林。
Abstract:
The changes of microbial biomass and enzyme activity of soils in different secondary succession stages of evergreen broadleaved forest on Tiantai Mountain in Zhejiang Province were analyzed by the method of spatial sequence instad of temporal sequence. The results showed that the content of soil organic matter, total nitrogen and total phosphorus increased in different secondary succession stages from scrub grass to evergreen broadleaved forests. The soil microbial biomass in the stage of scrub grass was the lowest, soil microbial carbon increased from needle forest to evergreen broadleaved forest, while soil microbial nitrogen decreased in the stage of needle broadleaved mixed forest, evergreen broadleaved forest and needle forest gradually . The activities of soil acid phosphatase, urease and βDglucosidase were the lowest in the stage of scrub grass. The activities of soil urease and βDglucosidase ranked in a decreased order of evergreen broadleaved forest, needle broadleaved mixed forest and needle forest, while the activity of soil acid phosphatase ranked in a decreased order of evergreen broadleaved forest, needle forest and needle broadleaved mixed forest.
