| 摘 要： | 从植物一土壤碳氮循环入手，对比研究外来入侵种飞机草、紫茎泽兰，土著种泽兰、佩兰与土壤间碳氮循环的差异，结果表明，飞机草和紫茎泽兰极大改变了生态系统中的碳、氮流，有利于加速被入侵生态系统的养分循环；且显著甚至极显著增大了生态系统中的植物碳、氮库，对土壤碳、氮库有影响但不显著；因此加快了生态系统的碳、氮循环，且这种改变对其自身有正反馈效应，这可能是其入侵成功的机制之一。

| Abstract: | Starting from the plant-soil nitrogen and carbon cycle,the difference of C and N cycle of exotic invasive plants Eupatorium odoratum and E.adenophorum and relative native species E.japonicum and E.fortunei and soil were compared and studied.The results showed that C and N flux in the ecosystem were changed patently by E.odoratum and E.adenophorum,which was propitious to quicken nutrient cycling of invaded ecosystem.Meanwhile,C and N stock in plants were multiplied extremely and remarkably and soil C and N s... |
