摘要
调查神东矿区23个单位附属绿地42种绿化树种共8464株,实地观测其各项生长指标、功能效益(滞尘、固定CO2、释放O2、降温等)以及蒸腾耗水量,同时对其健康等级、生态适应性(耐旱、耐风沙等)、美感作出评定,分析相对优势度等其他相关参数,最后将这些指标结合起来,用灰色关联分析法综合评价这42种树种的优先选择顺序。结果表明:在诸如神东矿区半干旱地区选择城市绿化树种时,落叶阔叶乔木树种应优先选择新疆杨、垂柳、小叶杨、国槐、龙爪槐、龙爪柳等;花灌木树种应优先选择华北紫丁香、黄刺玫、紫穗槐、华北珍珠梅等;常绿针叶树种优先选择顺序为:圆柏、云杉、樟子松、杜松、油松、侧柏。另外,榆树、柽柳和黄芦木总体表现较差,应适当少选。
Twenty-three urban accessory greenlands of branches with 8 464 woody landscape plants belonging to 42 species （cultivars/variations etc. ） in Shendong mining area were investigated, and growth conditions, function benefits （dust retention, CO2 fixation,O2 release, air temperature reduction, etc. ） and water transpirations of all different kinds of woody landscape plants were measured. Simultaneously, their health grades, ecological adaptabilities （drought tolerance, wind drift sand tolerance, etc. ） and scenic beauty were evaluated. In addition, other relevant indexes such as relative abundance were also analyzed. Finally, combined with those indexes mentioned above, preferential selection order of 42 kinds of woody landscape plants were comprehensively appraised by means of Gray Relation Analysis. The results were as follows： in urban accessory greenlands of branches in semi-arid areas such as Shendong mining area, Populus alba var. pyramidalis, Salix babylonica, Populus simonii, Sophora japonica, Sophora japonica f. pendula, Salix matsudana f. tortuosa, etc. should be selected preferentially for deciduous and broad-leaved arbors, and Syringa oblata, Rosa xanthina, Amorpha fruticosa, Sorbaria kirilowii etc. for shrubs; evergreen conifers should be selected in the order of Sabina chinensis 〉 Picea asperata 〉 Pinus sylvestris var. mongolica 〉 Juniperus rigida 〉 Pinus tabulaeformis 〉 Platycladus orientalis ; While Ulmus pumila, Tamarix chinensis and Berberis amurensis should be lastly considered.
