| 摘 要： | 为探讨不同人工林经营模式对土壤肥力的影响，该研究于2000年在北京九龙山地区设立样地，对华北落叶松、油松、白蜡人工林和椴栎杨天然次生林的枯枝落叶数量、养分含量、分解速率和养分归还量进行研究和分析。结果表明:①林下枯枝落叶储量的顺序为:油松椴栎杨落叶松白蜡；②单位面积各营养元素的总量与枯枝落叶的储量及营养元素含量成正相关关系；③落叶松、椴栎杨林下枯枝落叶分解较快，油松和白蜡相对较慢；④对于枯枝落叶归还到土壤中的N、P、K数量,落叶松人工林最大，其次为椴栎杨天然次生林，油松和白蜡人工林最少。

| Abstract: | In order to study the effects of various plantation management models on soil fertility,in 2000,the quantity,nutrition,composition and decomposing rate of litter layer in the plantations of Larix principis-rupprechtii,Pinus tabulaeformis,Fraxinus chinensis and secondary forests mixed by Tilia mandshurica,T.mongolica,Quercus liaotungensis and Populus davidiana were studied in the sample plots of Jiulongshan Mountains in Beijing.The results showed that: 1) litter storage under the plantations and forests foll... |
