According to the local weather data, the potential evapotranspiration of artificial Pinus tabulaeformis, Robinia pseudoacacia and Malus pumila in the west of Shanxi Province was calculated and analyzed by both Penman’s formula and Thornthwaita’s formula.According to the result and the water consumption coefficients of the water demands of artificial Pinus tabulaeformis, Robinia pseudoacacia and Malus pumila in their growing period (May-Oct.) were worked out respectively.Then the water supply-demand equilibriums were analyzed.The results show that: calculate out quota of water requirement of the main plantation tree species such as Pinus tabulaeformis, Robinia pseudoacacia and Malus pumila estimate annual water consumption of the main plantation tree species of different age.The 5 age-class annual water consumption of Robinia pseudoacacia are: biyearly: 390.65 mm, triennium: 398.85 mm, lustrum: 411.4 mm, septennial: 529.7 mm and the thirteen years: 633.95 mm.The 3 age-class annual water consumption of Pinus tabulaeformis are: 17~19 years: 653.5 mm; 19~20 years: 658.7 mm; 25~28 years: 655.6 mm.The 2 age-class annual water consumption of Malus pumila are: four years: 319.9 mm; eight years: 526.35 mm.At the same time we ascertain the monthly water requirement and annual change trend of water consumption of different age-class.
