Soil Chemistry for the Hubbard Brook Valley Plots, 1997 - 1998 Survey Data

The valley-wide plots are a grid of 431 sites along fifteen N–S transects established at 500-m intervals spanning the entire Hubbard Brook Valley. Multiple above- and below- ground attributes were measured between 1995 and 1998. This dataset includes soil chemistry data; tree inventory, additional soil data and other measurements are presented in separate datasets. These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.

本河谷全域样地为沿15条南北向样带布设的431个样点网格，样带以500米为间隔设置，覆盖整个哈伯布鲁克河谷（Hubbard Brook Valley）。1995年至1998年间，研究人员测定了多项地上与地下属性指标。本数据集包含土壤化学数据；林木调查数据、补充土壤数据及其他测量项均收录于独立数据集。上述数据为哈伯布鲁克生态研究（Hubbard Brook Ecosystem Study, HBES）的采集成果之一。该研究是依托哈伯布鲁克实验林（Hubbard Brook Experimental Forest）开展的协作项目，该实验林由美国农业部林务局北部研究站（USDA Forest Service, Northern Research Station）运营维护。
