以13年生油松人工林为研究对象，采用树高生长模拟、逐步回归、生长指数等方法，考虑降水和整地蓄水作用，估计黄土高原地区油松正常生长的最低需水量，结果表明：油松正常生长的最低需水量为540 mm，并据此计算出不同降雨量下的集水区大小。

The 13 a old Pinus tabulaeformis plantation was taken as study object to determine the minimum wa-ter requirement for its normal growth under the natural conditions in the Loess Plateau by means of height growth simulation,stepwise regression,height growth index,and by integrating the precipitation with water storage capaci-ty of the soil after site preparation.The results showed that the minimum water requirement for normal growth of P. tabulaeformis in the Loess Plateau was 540 mm.And the area of water collection under different precipitation scale was calculated on the basis of minimum water requirement.
