    日本中部风景林凋落物量、养分归还量

    Study on Litterfall, Nutrient Returned by Litterfall and Nutrient Use Efficiency in Scenic Forests of Central Japan

    • 摘要: 研究了日本中部的3个风景林-常绿针叶林、常绿阔叶林和常绿落叶阔叶混交林的凋落物,养分归还量和养分利用效率。常绿针叶林、常绿阔叶林和常绿落叶阔叶混交林的年凋落量分别为7562、6023和5565kg/hm^2,养分年归还量分别为233.87、125.20t 140.23kg/hm^2,各养分中N、K和Ca的归还量大于P和Mg叶的养分归还量占养分年归还量的64.19%-79.29%。常绿针叶林和常绿阔叶林中 Mg的利用效率高,表明Mg可能是这2种风景林生长的限制因子。
