主要讨论了闽南绿竹(Dendrocalamopsisoldhami)林C、N元素的含量、库存量、年动态及C/N。结果表明:(1)绿竹林各组分C、N元素含量有一定差异,含量范围分别为:C38.74%~44.77%、No.557%~1.012%;C/N在38.281~77.792之间。(2)绿竹林C、N元素的现存库存量分别为6760.0369/m2和112.3979/m2,其中地上部分别为5891.5739/m2和94.101g/m2;地下部分别为868.463g/m2和18.296g/m2。(3)1996年7月至1997年6月一年中绿竹叶的C、N元素含量基本上是在生长期的春末夏初含量高,在冬季含量低:C/N在24.707~38.281之间,在生长期的春季比例低,在冬季比例高。(4)绿竹细根的分解过程中C、N元素含量处于释放或累积的相间波动之中,而C/N在细根分解的前几个月下降,而后处于上升和下降的波动之中。
The contents of C and N in Dendrocalamopsisoldhami forest, stock quantity, annual dynamics and C / N were mainly discussed. The results showed that: (1) The contents of C and N in the components of P. mongolicus differed from one another in the range of C38.74% ~ 44.77%, respectively. 557% ~ 1.012%; C / N between 38.281 ~ 77.792. (2) The existing stocks of C and N elements in green bamboo forest were 6760.0369 / m2 and 112.3979 / m2 respectively, of which 5891.5739 / m2 and 94.101g / m2 respectively in aboveground part and 868 in underground part. 463 g / m2 and 18.296 g / m2. (3) The contents of C and N in the leaves of bamboo leaves from July 1996 to June 1997 were basically high in early spring and early summer and low in winter: C / N was 24.707 ~ 38.281, the low proportion of the spring season in the growing season, the high proportion in the winter. (4) During the decomposition process of fine bamboo roots, the contents of C and N were in the phase of release or accumulation, while C / N decreased in the first few months of fine root decomposition and then fluctuated in ascending and descending .
