Microclimate Measurements from the Terrestrial Gradient Plots, Coweeta Hydrologic Laboratory, North Carolina

The terrestrial gradient study at Coweeta compares vegetation, soils, and understory microclimate of five sites: 118 low elevation (782 m) pine-oak, 218 low elevation (795 m) cove hardwood, 318 low elevation (865 m) mixed oak, 427 high elevation (1001 m) mixed oak, 527 high elevation (1347 m) northern hardwood. Understory microclimate stations were installed in representative locations at the downslope margin of each 20 x 40 m gradient plot (within the 80 x 80 m plot).考伊塔（Coweeta）陆地梯度研究对5个样地的植被、土壤及林下微气候开展对比分析：118号低海拔（782米）松栎混交林、218号低海拔（795米）沟谷阔叶硬木林、318号低海拔（865米）杂栎混交林、427号高海拔（1001米）杂栎混交林，以及527号高海拔（1347米）北温带硬木林。林下微气候监测站布设于每个20×40米梯度样地的下坡边缘代表性点位，该点位位于80×80米样地范围内。
