Water use efficiency of six woody species in relation to micro-environmental factors of different habitats
六种木本植物水分利用效率和其小生境关系研究

The long term water use efficiency (WUE),of key species in deciduous broad-leaved forest in Beijing Mountain area,is strongly related to relative humidity,solar radiation,vapor pressure deficit and temperature. The ranges of water use efficiencies of Quercus liaotungensis,Prunus armeniac var. ansu, Fraxinus rhychophylla, Vitex negundo, Syringa pekingensis, and Juglans mandshurica are from 3 76 mmolCO 2·mol -1H 2O to 4 95mmolCO 2·mol -1H 2O in all growing season,with the mean water use efficiency b...
