摘　　要：岷江干旱河谷是我国西部生态环境最恶劣的地区之一。为给该地区植被的恢复与重建过程中提供理论依据,本实验针对其特点,从造林树种选择及其造林方法进行了研究。本试验选择了抗旱能力相对较强的针叶树种:岷江柏、油松、辐射松、白皮松与阔叶树种:密牧豆、元宝枫、榆树、刺槐进行研究,发现岷江柏的成活率最高,达到了89.6%,其次白皮松(89.5%)>榆树(86.7%)>油松(85.8%),都达到了85%以上,再次是刺槐(78.9%);元宝枫(59.1%)、密牧豆较差(53.0%),辐射松最低(50.5%)。同时还开展了采用黑地膜、白地膜、石块覆盖以及不加覆盖物(对照)4种处理方式对林木成活与生长的研究,结果表明:从处理方式上看,表现为覆盖处理均较对照好,其中以白地膜处理下表现最好,成活率达81.8%,黑地膜表现次之,而对照最差,生长量也以白地膜处理下表现最好,对照最差。The arid valleys of the Minjiang River is the worst ecotope in West China. For the restoration and recovery of vegetation in these areas, a study is directed toward the choice of forestation tree species and planting methods. In the experiment, authors chose 4 coniferous tree species （ Cupressus chengiana, Pinus tabulaeformis,Pinus radiata,Pinus bungeana ） and 4 broadleaved tree species （ Prosopis alba,Acer buergerianum,Robinia pseudoacacia,Ulmus pumila L） which have a better the drought-resistant ability. The results of their survival rate showed that Cupressus chengiana was the best,reaching to 89. 6% ,then Pinus bungeana （89.5%） 〉Roblnia pseudoacacia （86. 7% ） 〉Pinus tabulaeformis（85.8% ）. Their survival rates were more than 85%. Then it was Ulmus pumila L （78.9%） ,Acer buergerianum （59. 1% ）, Prosopis alba （53.0%） in turn,which showed worse ,and Pinus bungeana （50. 5% ） showed the worst. At the same time, a study was made of the growth of tree species which were treated with different mulching. Under different mulching treatment, the result showed that all treatments were better than antitheses and the white membrane treatment was the best which showed 81.8% in the survival rate ,the black membrane treatment took the second place and the antitheses was the worst. The growth yield showed that the white membrane treatment was the best and the antitheses was the worst.
