摘　　要：岷江干旱河谷区长期处于缺水的自然环境之下,在岷江干旱河谷造林树种选择上,一般选用耐旱树种,节水造林。由于岷江干旱河谷的降水量小,植物蒸发量远远大于降水量,这样的生长环境导致了植物生长缓慢。目前,水分子成为限制岷江干旱河谷造林的关键因素。由此,展开对岷江干旱河谷造林树种耗水性的研究,也是研究岷江干旱河谷造林树种选择的关键所在,该篇致力于协调造林植被与河谷水资源的关系,主要以辐射松、油松、榆树、岷江柏和侧柏五个树种为研究对象,展开岷江干旱河谷造林树种选择。The arid valley of Minjiang River has gone the natural environment of water shortage for a long time. In the selection of afforestation species in the arid valley of the Minjiang River, the drought resistant tree species are selected to save water for afforestation. Because of the small amount of precipitation in the dry valley of the Minjiang River, the evaporation of the plant is far greater than that of the precipitation, At present, the water molecule is the key factor to restrict the afforestation in the dry valley of Minjiang river. Therefore, the study on water consumption of afforestation tree species in the arid valley of the Minjiang River was carried out and has been the key to the study on the selection of afforestation species in the dry valley. The the article devoted to the coordination of water re- sources and river valley vegetation afforestation, mainly in radiata pine, pine, elm, Cupressus of Platycladus orien- talis and five species as the research object, to carry out in the dry valley afforestation tree species selection.
