Log Decomposition Dynamics in Interior Alaska 4 - Nutrient 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 sample nutrient analysis data for 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序研究的详实数据。本次研究的受试树种包括白云杉、黑云杉、美洲山杨、桦木、香脂杨，以及初始为活立木的美洲山杨；此外，数据集还纳入了近期过火区域内的白云杉与黑云杉样本。本研究旨在获取未来百年间的原木分解时序测量数据，其监测指标涵盖：原木在特定时段内的重量与密度变化、营养物质浓度变化，以及半纤维素、纤维素与木质素的浓度变化，同时包括营养物质、半纤维素、纤维素及木质素的含量变化。（本文件收录了本次原木分解研究的营养物质分析样本数据。）
