Contact rthe author, David Nowak, at [e-mail] Tags Biophysical Resources, Land, Social Institutions, Health, BES, Soil, Lead, Sample, UFORE Summary Samples were taken to relate soil data to vegetation data obtained for the Urban Forestry Effects Model (UFORE). Description The data is soil concentrations and characteristics of the following: land use, bulk density, sand, silt, clay, pH, organic matter, nitrogen, Al, P, S, Ti, Cr, Mn, Fe, Co, Ni, Cu Zn, Mo, Pb, Cd, Na, Mg, K, Ca, and V. Soils were sampled in 125 plots located within the City of Baltimore in the summer of 2000. The plots were randomly stratified by Anderson Land Cover Classification System Level II, which included commercial, industrial, institutional, transportation right-of-ways, high and medium density residential (there were no low density residential areas identified within the city boundaries), golf course, park, urban open, forest, and wetland land-use types. The number of plots situated in each land-use type was weighted to their proportion of spatial area within the City. The resultant number of plots sampled for soil by land-use type was: commercial (n = 2); industrial (n = 3); institutional (n = 10); transportation right-of-ways (n = 7); high density residential (n = 19); medium density residential (n = 33); golf course (n = 3); riparian (n=2); park (n = 10); urban open (n = 10); and forest (n = 26) land-use types, respectively. The distribution of plots represents the proportion of area covered by impervious surfaces.

摘要：本数据集采集土壤样本旨在将土壤数据与城市森林效应模型（Urban Forestry Effects Model，UFORE）获取的植被数据相关联。
描述：本数据集包含以下土壤浓度与特征数据：土地利用类型、容重、砂粒、粉粒、黏粒、pH值、有机质、氮、铝（Al）、磷（P）、硫（S）、钛（Ti）、铬（Cr）、锰（Mn）、铁（Fe）、钴（Co）、镍（Ni）、铜（Cu）、锌（Zn）、钼（Mo）、铅（Pb）、镉（Cd）、钠（Na）、镁（Mg）、钾（K）、钙（Ca）以及钒（V）。2000年夏季，研究人员于美国巴尔的摩市内125个样地中采集土壤样本。样地依据安德森土地覆盖分类系统二级（Anderson Land Cover Classification System Level II）进行随机分层，涵盖商业用地、工业用地、公共机构用地、交通通行廊道用地、高密度住宅区、中密度住宅区（城市范围内未识别出低密度住宅区）、高尔夫球场、公园、城市开放空间、森林以及湿地等土地利用类型。各土地利用类型的样地数量依据其在城市内的空间面积占比进行加权。各土地利用类型的土壤采样样地数量如下：商业用地（n=2）、工业用地（n=3）、公共机构用地（n=10）、交通通行廊道用地（n=7）、高密度住宅区（n=19）、中密度住宅区（n=33）、高尔夫球场（n=3）、河岸地带（n=2）、公园（n=10）、城市开放空间（n=10）以及森林（n=26）。样地分布反映了区域不透水面的面积占比情况。
