Description

Supplement_data.txt is a tab-separated file. It contains the data compiled from literature-sourced data, information about compilation methods, and sources.

Column definitions:

1.RECORD_ID - record number.

2.SOURCE_ID - record number of reference used as data source (see list of references below).

3.SOURCE - short name for reference.

4.SITE - study site.

5.COUNTRY - country of study site.

6.REGION - region (province, state, other) of study site.

7.ECOZONE - Canadian ecozone if site in Canada or assigned to some sites in United States as the bordering Canadian ecozone.

8.SNAG_SP - tree species of snag

9.SPECIES_GROUP - species group category assigned to record based on the SNAG_SP or lead species of the study site.

10.OTHER_DESCRIPTOR - additional information about site or trees.

11.SNAG_FALL_ANNUAL - annual fall rate (%/yr) of standing dead tree stems meeting dbh criteria as Snag_Stemwood pool in CBM-CFS3 (Kurz et al. 2009).

12.SNAGBRANCH_FALLRATE - annual fall rate (%/yr) of standing dead material of non-merchantable trees, saplings, branches of merchantable-sized trees as in the SnagBranches pool of CBM-CFS3 (Kurz et al. 2009).

13.SNAGFALL_CALC_METHOD - brief description of data type used from literature source to calculate SNAG_FALL_ANNUAL, see methods in manuscript (Hilger et al. XXXX) for details of calculation methods based on T50 (mean half-life or time to 50% of snags fallen), individual % of stems fallen at a given time(s), or where values were derived from exponential k values.

14.SNAGBRANCH_FALLRATE_CALC - brief description of how data in reference was used to calculate SNAGBRANCH_FALLRATE.

描述

Supplement_data.txt 为制表符分隔文件，包含从文献中汇编得到的数据、汇编方法相关说明以及数据来源。

列定义：
1. 记录编号（RECORD_ID）：单条记录的编号。
2. 数据源记录编号（SOURCE_ID）：用作数据来源的参考文献的记录编号（详见下文参考文献列表）。
3. 参考文献简称（SOURCE）：对应参考文献的简短名称。
4. 研究站点（SITE）：开展研究的站点位置。
5. 所属国家（COUNTRY）：研究站点所在的国家。
6. 所属区域（REGION）：研究站点所属的行政区域（省、州或其他同级单元）。
7. 生态区（ECOZONE）：若站点位于加拿大，或美国部分毗邻加拿大的站点所归属的加拿大生态区。
8. 枯立木树种（SNAG_SP）：枯立木所属的树种。
9. 物种组类别（SPECIES_GROUP）：基于枯立木树种（SNAG_SP）或研究站点优势树种分配得到的物种组分类。
10. 附加描述符（OTHER_DESCRIPTOR）：关于研究站点或树木的补充信息。
11. 年枯倒速率（SNAG_FALL_ANNUAL）：符合CBM-CFS3模型（Kurz等，2009）中枯立木茎干库（Snag_Stemwood pool）胸径（DBH）标准的枯立木茎干的年枯倒率（%/年）。
12. 枯立枝条年枯倒速率（SNAGBRANCH_FALLRATE）：对应CBM-CFS3模型中枯立枝条库（SnagBranches pool）的非商用树木、幼树以及商用规格树木枝条的枯立物的年枯倒率（%/年）。
13. 枯立木茎干枯倒率计算方法（SNAGFALL_CALC_METHOD）：对用于计算SNAG_FALL_ANNUAL的文献数据源类型的简要说明，详细计算方法参见手稿（Hilger等，XXXX）中基于T50（平均半衰期或50%枯立木茎干枯倒所需时间）、特定时间点茎干枯倒百分比，或由指数k值推导所得值的相关方法。
14. 枯立枝条枯倒率计算方法（SNAGBRANCH_FALLRATE_CALC）：对参考文献中用于计算SNAGBRANCH_FALLRATE的方法的简要说明。
