Log Decomposition Dynamics in Interior Alaska 5b - Preliminary Results (treatment down) - Retained

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 preliminary retention results for the treatment=down part of the study.)本完整数据集（共7个文件）涵盖了阿拉斯加内陆地区原木分解时序研究的详细资料。研究涉及的树种包括白云杉（white spruce）、黑云杉（black spruce）、美洲山杨（aspen）、桦木（birch）及香脂杨（balsam poplar），所有树种初始状态均为活立木；原文存在重复的美洲山杨表述，疑为输入笔误。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100年内的原木分解时序监测数据。原木待监测指标包括：指定时段内的重量与密度变化、养分浓度变化，半纤维素（hemicellulose）、纤维素（cellulose，原文拼写为cellouse，疑为笔误）与木质素（lignin）的浓度变化，以及养分、半纤维素、纤维素与木质素的含量变化。（本文件包含该研究中"处理组=倒伏木"部分的初步留存结果。）
