Above ground plant biomass in a mesic acidic tussock tundra experimental site from 1982 to 2000 Arctic LTER, Toolik Lake, Alaska.

Above ground plant biomass and leaf area were measured in a moist acidic tussock tundra experimental site. The plots were set up in 1981 and have been harvested in periodical (See Shaver and Chapin Ecological Monographs, 61(1), 1991 pp.1-31. Mack, et al, Nature 2004 431:440-443) This file contains the biomass numbers for each harvested quadrat and per cent carbon and nitrogen summaries for harvests through 2000. Leaf area data is presented in other data files (see http://ecosystems.mbl.edu/arc).

本数据集采集于湿润酸性丛状苔原实验样地，针对地上植物生物量与叶面积开展测定。实验样地于1981年布设，并已进行周期性收割（参考文献：Shaver与Chapin，《生态专著（Ecological Monographs）》，61(1)，1991年，第1-31页；Mack等，《自然（Nature）》，2004年，431卷：440-443页）。本文件包含各收割样方的生物量数据，以及截至2000年所有收割批次的碳、氮百分含量汇总结果。叶面积数据详见其他数据集文件，访问地址：http://ecosystems.mbl.edu/arc。
