【摘要】 对衡水市18种园林绿化植物进行阻滞尘埃能力和城市环境适应性评价,综合这两项指标发现:衡水市城市绿化植物中,针叶树种油松的得分较高;阔叶乔木类中,国槐和栾树的得分较高,白蜡的适中,法梧、碧桃得分较低;对于灌木类,大叶黄杨、紫叶小檗、金叶女贞的得分较高,连翘的适应能力强;草本植物相比较而言,滞尘效果低于木本植物,但白车轴草、八宝景天、萱草对环境的适应能力较强;引进植物锦熟黄杨、扶芳藤和络石的阻滞尘埃能力均较强,但锦熟黄杨和络石在衡水适应性差,越冬需加防寒措施,扶芳藤适应能力较强。更多还原

【Abstract】 The ability of dust detention and adaptability to urban environment of 18 kinds of green plants in Hengshui City are studied. Considering these two indicators, the results show that the grade of Pinus tabulaeformis Carr. is the highest among the urban green plants in Hengshui City. For broad-leaved trees, Sophura japonica L. and Koelreuteria paniculata Laxm. have higher grades; Fraxinus chinensis Roxb. has a moderate grade, and Platanus Orientalis L. and Amygdalus persica L. get lower grades. For shrubs, Euonymus. Japonicus Thunb., Berberis thunbergii cv Atropurpurea and Ligustrumxvicaryi all have higher grades, and the adaptability of Forsythia suspensa is strong. The research shows that the ability of dust detention of woody plants is better than that of herbal ones. However, the adaptability of Trifolium repens, Sedum spectabile Boreau and Hemerocallis aurantiaca to the environment is strong. For the introduced plants, such as Buxus sempervirens L., Euonymusfortunei(Turcz.) Hand. Mazz. and Trachelospermum jasminoides(Lindl.) Lem, the ability to block the dust is relatively strong, but Buxus sempervirens L. and Trachelospermum jasminoides(Lindl.) Lem. have poor adaptability, and it is necessary to take cold-proof measures to help them overwinter. Euonymusfortunei(Turcz.) Hand. Mazz. has a strong adaptability in Hengshui City.更多还原
