GIS file of permafrost distribution in Caribou-Poker Creeks Research Watershed

Rieger et al. (1972) described the soils of Caribou-Poker Creeks Research Watershed, near Fairbanks, Alaska. Permafrost soils were described and a map of their distribution created. This dataset consists of a digitized spatial data layer of the original permafrost map in ESRI shapefile format.里格等（Rieger et al.，1972）对位于阿拉斯加州费尔班克斯附近的驯鹿-波克河研究流域（Caribou-Poker Creeks Research Watershed）的土壤开展了调研与描述。研究针对该区域的永久冻土土壤（permafrost soils）进行了详细阐释，并绘制了其空间分布地图。本数据集包含该原始永久冻土地图的数字化空间数据图层，格式为ESRI形状文件（shapefile）。
