In the present paper,the floristic characteristics,community structure,population structure,spatial distribution and regeneration pattern of Cryptomeria fortunei were analyzed and discussed at 1 100 m on Mt.

运用系统的群落学调查方法对天目山分布于海拔1100m处的柳杉Cryptomeriafortunei群落进行调查，分析其种类组成和群落结构特征，并对柳杉的种群结构和分布格局进行了探讨。

Biomass and soil organic carbon dynamics of Cryptomeria fortunei plantations at 5,10,17,22 and 26 years-old were studied at Pengzhou County,Sichuan Province,employing volume-biomass method and soil profile investigation.

以四川彭州为典型案例，采用材积源生物量法和土壤剖面分析方法，对栽植5、10、17、22和26年的人工柳杉林生物量及其土壤碳动态进行了初步研究。

15 Nests were found in the study and about 86. 7% of them were located in the Cryptomeria woodland, 80% of the nesting trees were C. fortunei.

To address the issue, we analyze the correlation and similarity of the different radii sequence and the different combination sequence with the full- ring-sample sequences, based on 642 δ13C data of cellulose fixed in tree-ring at 8 different radii of two Cryptomeria fortunei tree disks from Mt. Tianmu, a subtropical mountain of China. It suggests that 2 to 4 radii mixture sample is the better and more efficient choice for the tree-ring δ13C analysis. It had better to take samples at obtuse angle with each other when to take samples at two or three radii.

研究利用来自天目山的两个柳杉树盘的多方位的和整轮的碳同位素测试数据（共计642个），通过不同方位和不同方位组合的平均碳同位素序列与整轮碳同位素序列的关系的多角度的考查、分析发现，并不是采样的方位数越多越好，选择2~4个方位采样合并分析树轮稳定碳同位素，既经济方便又能比较好的反映一棵树的δ13C变化过程与趋势。

According to the data of the analyses,revealed the population of Cryptomeria fortunei exhibited clump distribution pattern,single-dominant community type,sporadic type population structure and is able to natural regenerate...

柳杉种群呈典型的集群分布，并随个体的增大，由集群分布向随机分布发展的趋势，为间歇型的种群结构。通过对天目山柳杉的起源及其更新类型的探讨表明：天目山柳杉林属天然林与人工林共存状态，并可通过幼苗库进行天然更新，但具有机会性和波动性，需林窗和林内倒木等条件。图3表2参25

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
