| 摘 要： | 研究比较第2代连载杉木纯林、杉木与火力楠混交林以及火力楠纯林3种人工林生态系统的C、N贮量。结果表明,杉木与火力楠混交林生态系统C贮量要高于杉木纯林和火力楠纯林,而生态系统N贮量是火力楠纯林和杉木与火力楠混交林高于杉木纯林;生态系统C和N贮量的空间分布基本一致,土壤层占主要部分,其次为乔木层,再次是根系,林下植被层和凋落层所占比例最小;相关分析表明,土壤C、N贮量分别和林下植被生物量以及与森林凋落物现存量之间都具有良好的线性关系,说明林下植被和森林凋落物对土壤C、N贮量有着深刻的影响。 |

| Abstract: | Chinese fir(Cunningharnia lanceolata),a type of subtropical fast-growing conifer tree,widely distributed in South China,and its plantation area in China is more than 7×10~6 hm~2,accounting for 24% of total area of plantation forest in China.In recent decades,the system of successive plantation of Chinese fir is widely used in the southern china for an anticipated high economic return.However,recent studies have documented that the practice of this system led to dramatic decreases in soil fertility and fores... |
| Keywords: | Chinese fir plantation mixtures of Chinese fir and broad-leaved forest carbon stock nitrogen stock |
