中文摘要	为了研究树木生长水势阈和生命水势阚，在干旱、半干旱地区测定研究了樟子松、油松、侧柏、白扦、沙棘、新疆杨和白刺在不同水分状况下的吸水特征、光合作用年进程。结果指出树木生长水势阈和生命水势阈具有树种差异和树木年生长发育时期的变化，年生长末期较宽，对水分胁迫适应性强的树种较宽。嫩枝生长期各树种生长水势阈（Mpa）排序：侧柏〉樟子松〉油松〉白刺〉沙棘〉白扦〉新疆杨；各树种生命水势阈（Mpa）排序：沙棘〉油松〉白剌〉樟子松〉白扦〉侧柏〉新疆杨
英文摘要	The growth water potential field and life water potential field were studied by mensurating the absorbing water indexes and the photosynthes under the different water conditions in the annual growth course of the tested trees. The results indicated the growth water potential field and life water potential field had difference between tree soecies and defferent periods of the annual growth. They were greater in the last period of growth season of trees, and in the tree species their adaptability to water stress was stonger. The tree species order by the growth water potential field in the period of the new brunch growth is: Platycladus orient alls >Pinus syJvestris var. mongolica ~>Pinus tahulaeformis ^>Nitraria tan-gutorum ^>Hippophae rhamnoides ^>Picea meyeri ^>Populus alba cv. pyramidalis ; The tree species order by the life water is-.H. rhamnoides >P. tabulaeformis >7V. tangutorum >P. sylvestris var. mongolica >P. meyeri >P. orientalis > P. alba cv. pyramidalis
