Log Decomposition Dynamics in Interior Alaska 2a - Log Data

The entire dataset (all 7 files) contains detailed information on a time series study of log decomposition in interior Alaska. The species studied include white and black spruce, aspen, birch, balsam poplar and aspen starting as green trees. In addition white and black spruce in recently burned sites are included. The study was designed to produce a time series of log decomposition measurements over the next 100 years. The information to be measured on the logs includes weight and density changes over specified time periods, changes in nutrient concentrations, and hemicellulose, cellouse, and lignin concentrations, and changes in the quantity of nutrients and hemicellulose, cellouse and lignin. (This file contains the time zero tree and log physical measurement, and site mapping data for the log decomposition study.)本完整数据集（含全部7个文件）涵盖阿拉斯加内陆地区原木分解时序研究的详细信息。本次研究涉及的树种包括白云杉（white spruce）、黑云杉（black spruce）、颤杨（aspen）、桦木（birch）、香脂杨（balsam poplar），以及初始状态为活立木的颤杨。此外，数据集还纳入了近期过火林地内的白云杉与黑云杉样本。本研究旨在获取未来100年内原木分解的时序监测数据，原木待监测的指标包括：特定时段内的重量与密度变化、养分浓度变化，以及半纤维素（hemicellulose）、纤维素（cellulose，原文拼写为cellouse）、木质素（lignin）浓度变化，同时还包括养分、半纤维素、纤维素与木质素的含量变化。（本文件包含原木分解研究的零时刻活立木与原木物理测量数据，以及样地测绘数据。）
