摘要: Rooftop gardening or green roof establishment, one of the methods afforestation for urban greening, has many benefits environment, economy and landscapes. Various environmental stresses including heat, strong wind, sunshine cold prevent most plants from growing well in extensive systems. For establishment rooftop Beijing, we evaluated 13 ornamental plant species [Berberis thunbergii ‘Atropurea Nana’, Euonymus fortune (Turcz.) Hand., Viburnum dilatatum Thunb., Cotinus coggygria Scop., Swida alba Opiz., Weigela florida (Bunge.) A. DC., Jasminum nudiflorum Lindl., japonicus ‘Cuzhi’, Buddleja davidii Franch., Pyracantha fortuneana (Maxim.) Li., Ligustrum lucidum Ait. Spiraea salicifolia L.] greening flat rooftops. We obtained three indices concerning resistance, i.e., electrical conductivity leaves, amounts soluble sugars free proline, providing a theoretical basis selection fit balcony greening. The results show that six P. B. J. E. Thunb. ‘Cuzhi’ are excellent gardening, judging their ability resistance. Plants such as L. Ait., C. Scop. W. (Bunge) DC. showed medium However, these can be used after intensive management acclimatization variety. to resist S. L., V. rhytidophyllum Opiz. (Cornus L.) was found rather weak. Therefore, cold-proof measures recommended when using species.
