黄土高原油松正常生长的最低需水量估计
Estimation of Minimum Water Requirement for Normal Growth of Pinus tabulaeformis in Loess Plateau
摘要
Abstract
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.关键词
