资源简介:
Abundance of vascular plants measured using point intercept frequency.\r\n\r\nThe datasets contains point frequency data (which can be converted to biomass estimates) of the following functional groups and species:\r\n\r\n* Betula nana \r\n* Broad leaved grasses\r\n* Calamagrostis phragmitoides \r\n* Deciduous dwarf shrubs\r\n* Deciduous vascular cryptogams\r\n* Deschampsia cespitosa\r\n* Empetrum nigrum\r\n* Equisetum sp\r\n* Evergreen dwarf shrubs\r\n* Evergreen non woody\r\n* Green willows\r\n* Grey willows\r\n* Hemiparasites \r\n* Nardus stricta\r\n* Narrow leaved grasses\r\n* Prostrate willows\r\n* Rumex acetosa\r\n* Salix herbacea\r\n* Sedges and rushes\r\n* Small forbs\r\n* Tall forbs\r\n* Vaccinium myrtillus\r\n\r\n\r\nThe dataset includes three different types of files and all files (except the readme) are saved as ;-separated txt-files:\r\n \r\n* One data file per year (_YEAR.txt) \r\n* One coordinate file with coordinates of all sites included in the dataset (_coordinates.txt) \r\n* One auxiliary file with information about which sites are included in the dataset and when (_aux.txt) \r\n* One readme file with additional information about the variables included in the study design (_readme.pdf)\r\n\r\nThe dataset has a two-year embargo, older versions of the dataset are publicly available for download.\r\n

采用点截频度法(point intercept frequency)测定的维管植物(vascular plants)丰度。 本数据集包含以下功能群与物种的点频度数据(可转换为生物量估算值): * 矮桦(Betula nana) * 宽叶禾草(Broad leaved grasses) * 芦苇状拂子茅(Calamagrostis phragmitoides) * 落叶矮灌木(Deciduous dwarf shrubs) * 落叶维管隐花植物(Deciduous vascular cryptogams) * 丛生发草(Deschampsia cespitosa) * 岩高兰(Empetrum nigrum) * 木贼属(Equisetum sp.) * 常绿矮灌木(Evergreen dwarf shrubs) * 常绿非木本植物(Evergreen non woody) * 绿叶柳类(Green willows) * 灰叶柳类(Grey willows) * 半寄生植物(Hemiparasites) * 欧针茅(Nardus stricta) * 窄叶禾草(Narrow leaved grasses) * 匍匐柳类(Prostrate willows) * 酸模(Rumex acetosa) * 圆叶柳(Salix herbacea) * 莎草与灯心草(Sedges and rushes) * 小型杂类草(Small forbs) * 大型杂类草(Tall forbs) * 越橘(Vaccinium myrtillus) 本数据集包含三类文件,除README说明文件外,其余所有文件均以分号分隔的文本(;-separated txt-files)文件格式存储: * 按年份划分的数据文件(命名格式为_YEAR.txt) * 包含数据集内所有样点坐标的坐标文件(命名格式为_coordinates.txt) * 包含数据集涉及样点及其调查时间信息的辅助文件(命名格式为_aux.txt) * 包含研究设计变量相关补充信息的README说明文件(命名格式为_readme.pdf) 本数据集设有两年的保密期,旧版数据集可公开下载获取。
