Log Decomposition Dynamics in Interior Alaska 1 - Site 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 descriptive information and location data for the sites used in the log decomposition study.)本完整数据集（含全部7个文件）收录了阿拉斯加内陆地区原木分解时间序列研究的详细资料。研究涉及的物种涵盖初始状态为活立木的白云杉（white spruce）、黑云杉（black spruce）、美洲山杨（aspen）、桦木（birch）、香脂杨（balsam poplar）以及美洲山杨。此外，数据集还纳入了近期火烧迹地中的白云杉与黑云杉样本。本研究旨在构建未来100年内的原木分解时序监测数据集。原木待监测的指标包括：特定时段内的重量与密度变化、营养盐浓度变化，以及半纤维素（hemicellulose）、纤维素（cellulose）与木质素（lignin）的浓度变化，同时涵盖营养盐、半纤维素、纤维素与木质素的含量变化。（本文件收录了本次原木分解研究所用样地的描述性信息与位置数据。）
