摘　　要：为研究经济树种对干旱河谷环境的适应性,本文以岷江上游干旱河谷11种经济树种盆栽苗木为研究对象,测定各树种13个生理生化指标,并结合隶属函数法、灰色关联度分析及聚类分析对试验树种的生态适应性进行综合评价及评价指标的筛选。结果表明:(1)各树种的综合生态适应性指数(WCAI)排序为,巴旦木>西康扁桃>黄连木>四川黄栌>榛子>红翅槭>黑果枸杞>乌梅>沙棘>核桃>枸杞;(2)Gs、Ci、Tr、Pnmax 4个叶片光合气孔指标以及SOD、CAT 2个抗氧化酶活性指标等与树种适应性关系紧密,可以作为该地区经济树种筛选的关键评价指标。In order to study the adaptability of economic tree species to environment of the dry valley in the upper Minjiang river,13 physiological and biochemical indices of 11 tree species were determined.Subordinate function values analysis,grey relational analysis and clustering analysis were used to evaluate comprehensive adaptability of tree species and select evaluation indexes.The results showeded that:(1)Weight comprehensive adaptability index(WCAI)of each tree species was ranked as Amygdalus communis L.>Amygdalus tangutica(Batal.)Korsh.>Pistacia chinensis Bunge>Cotinus szechuanensis>Corylus heterophylla>Acer fabri Hance>Lycium ruthenicum Murr.>Armeniaca mume Sieb.>Hippophae rhamnoides>Juglans regia L.>Lycium chinense Mill.(2)Gs、Ci、Tr、Pnmax、SOD、CAT were closely correlated with the comprehensive adaptability of tree species,which could be used as the key evaluation indexes of economic tree species screening in the upper Minjiang river dry valley.
