Abstract：In order to select low water consumption vegetation species in cultivating the water conservation forest, the apparatus of lysimeter and TDR etc. are used in basin of water conservation in MiYun reservoir in Beijing. The water consumption characteristics are studied through comparison of average water consumption per day and consumption characteristics in different weather of six species with weighing methods. The results showed that in natural moisture condition, the water consumption per day of different species from min to max is Vitex negundovar, Pinus tabulaeformis, Ailanthus altissima, Platycladus orientalis , Poplar, Robinia pseudoacacia . In terms of average water consumption per day from July to September, Vitex negundo var. heterophylla living six years is 0 28kg, Pinus tabulaeformis living seven years is 0 57kg, Ailanthus altissima of living years is 0 55kg, Platycladus orientalis living seven years is 0 7kg, Poplar living three years is 0 77kg, Robinia pseudoacacia living five years is 0 78kg. The results indicated that Vitex negundo var. heterophylla and Pinus tabulaeformis are adapt to be cultivated in water conservation forest because of low water consumption.
