由于CO2在全球气候变化中的假设作用，碳储存和动态受到越来越多的关注。这项研究的目的是确定湖泊州森林中的总碳储量，包括生物量、森林地面和矿物土壤中的碳。上层树木进行了测量，森林地面和矿物质土壤（1米）的样本收集在明尼苏达州，威斯康星州，密歇根州的169个森林站的地块。结果表明，该地区有5种森林类型：香脂冷杉（Balsam fir）、冷杉（Abies balsamea（L.）米尔。短叶松，班克松。红松树（P. resinosa Ait.）白杨、山杨（Populus tremuloides Michx.）;和北方硬木为主的糖枫，糖槭沼泽。在整个研究区域，生物量、森林地面或矿物土壤中的碳储量没有明显的地理趋势。不同森林类型的储藏量差异很大。每个主要的C池都与一组不同的描述符相关。总碳储量，所有池的总和，有关的森林类型，林分年龄，有效水，实际蒸散量，土壤日含量，解释约65%的变化。使用土壤和站点描述符没有完全占森林类型对碳储量的强烈影响。碳池的大小的差异，有关的时间，因为干扰和森林类型，表明碳存储在森林的湖泊国家可以影响森林管理活动。在这些潮湿的温带生态系统中的C存储模式是不强烈的气候变量的影响，是C存储在草原西部。
Carbon storage and dynamics are receiving increasing attention because of the hypothesized role of CO2 in global climate change. This study was carried out to determine total C storage in Lake States' forests, including C in biomass, forest floor, and mineral soil. Over-story trees were measured and samples of both forest floor and mineral soil (to 1 m) were collected from plots in 169 forest stands across Minnesota, Wisconsin, and Michigan. Five forest types were represented: balsam fir, Abies balsamea (L.) Mill.; jack pine, Pinus banksiana Lamb.; red pine, P. resinosa Ait.; aspen, Populus tremuloides Michx.; and northern hardwoods dominated by sugar maple, Acer saccharum Marsh. There were no strong geographic trends in C storage in biomass, forest floor, or mineral soil across the study area. Storage differed significantly among forest types. Each major C pool was related to a different set of descriptors. Total C storage, the sum of all pools, was related to forest type, stand age, available water, actual evapotranspiration, and soil day content, explaining about 65% of the variation. Use of soil and site descriptors did not completely account for the strong effects of forest type on C storage. Differences in the size of C pools, as related to time since disturbance and forest type, indicate that C storage in forests of the Lake States can be influenced by forest management activities. Patterns of C storage in these moist temperate ecosystems are not as strongly influenced by climatic variables as is C storage in grasslands to the west.
