摘　　要：伊犁河谷生态经济林包括经济林、防护林、用材林和园林绿化4部分,本研究结合该地区生态环境特点和实际发展需求以及树种利用情况,以树种的生态适应性、生态功能、观赏性和经济性作为生态经济林树种选择的主要依据,选择抗旱性、抗寒性、耐盐性、抗病虫害等14个适宜性评价指标,采用3级评分制对各指标进行量化分级,运用指数和法对生态经济林参选树种进行综合评价。结果显示:经济林树种宜选用树上干杏(Armeniaca vulgaris)、苹果(Malus pumila)和葡萄(Vitis vinifera);防护林树种宜选用银×新(Populus alba×P.bolleana)和新疆杨(Populus alba var.pyramidalis);用材林树种宜选用夏橡(Quercus robur)、大叶白蜡(Fraxinus americana.)、小叶白蜡(Fraxinus sogdiana)和银×新;园林绿化树种宜选用夏橡、黄榆(Ulmus macrocarpa)、大叶白蜡、小叶白蜡、桦树(Betula platyphylla)、水曲柳(Fraxinus mands churica)、山桃(Persica davidiana)、三球悬铃木(Platanus orientalis),可供伊犁河谷生态经济林树种选择提供参考。Ecological economic forests in Yili Valley include economic forest,shelterbelt,timber forest,and garden.Combining the ecological environment characteristics with the actual demand and utilization of tree categories,the experiment was conducted to establish evaluation system for tree species selection in ecological economic forest.Based on ecological adaptability,ecological function,ornamental and economy character of tree species,14 suitability indices were selected including the drought resistance,cold resistance,salt tolerance,pest resistance,etc.,three grades scoring system was used to grade each norm,and index sum method was used to synthetically assess the selected tree species in ecological economic forest.The result showed that:Armeniaca vulgaris,Malus pumila,and Vitis vinifera were suitable for the economic forest tree species;Populus alba×P.bolleana,and P.alba var.pyramidalis were suitable for the shelterbelt tree species;Quercus robur,Fraxinus sogdiana,Fraxinus americana and P.alba×P.bolleana were suitable for the timber tree species;Q.robur,Ulmus macrocarpa,F.sogdiana,F.americana,Betula platyphylla,F.smands churica,Persica davidiana,Platanus orientalis were suitable for the garden tree species.The results could provide a reference for the selection of tree species in ecological economic forests in Yili Valley.
