LBA-ECO CD-04 LEAF LITTER DATA, KM 83 TOWER SITE, TAPAJOS NATIONAL FOREST, BRAZIL

Above-ground litter productivity was measured in a 18 ha plot adjacent to the eddy flux tower at the logged forest tower site, km 83, Tapajos National Forest, Para, Brazil. Thirty litter baskets distributed within the grid were visited bi-weekly (Goulden et al., 2004). Oven dry mass of leaves, wood, reproductive parts and miscellaneous components of the collected litter was determined for each collection. Collections covered a pre-harvest period (Sept 2000 - July 2001) and a post- harvest period (Aug 2001-Mar 2003). There is one comma-delimited data file with this data set.

本数据集针对巴西帕拉州塔帕若斯国家森林km83处采伐林通量塔（eddy flux tower）周边的18公顷样地，测定了地表枯落物生产力。在该样地网格内布设了30个枯落物收集框，每两周开展一次采样工作（Goulden等，2004）。针对每次采集到的枯落物，分别测定其叶片、木质组织、繁殖器官及其他杂项组分的烘干干重。采样时段涵盖采伐前期（2000年9月—2001年7月）与采伐后期（2001年8月—2003年3月）两个阶段。本数据集附带1个逗号分隔符格式的数据文件。
