江苏常州城市绿化应对高温干旱天气研究

Research about urban greening response to high temperature and dry weather in Changzhou Jiangsu

初步研究了高温干旱天气对城市绿化的影响。通过绿地调查统计发现:高大乔木在高温干旱天气下适应能力较强,而新种树木和色块对高温干旱天气的抵抗能力较弱;不同植物品种耐旱耐热性差异显著,受害较重的植物有银杏、香樟、红枫、广玉兰、小叶女贞、瓜子黄杨、八角金盘、洒金桃叶珊瑚等,而二球悬铃木、紫薇、黄山栾树、木槿、石楠等受害轻微;绿化种植和管理的不科学加重了植物受害的程度。对今后城市生态园林建设,必须采取必要措施来降低城市绿化受自然和人为灾害的影响。

The effect of high temperature and dry weather on urban greening was studied Preliminary. The study indicated that the tolerance ability of original tall tree against high temperature and dry weather is stronger than the other trees and small shrubs. Significant difference was found in the resistance to drought heat of different plant species such as Ginkgo biloba, Cinnamonum camphora, Acer palmatum cv. Atropurpureum, Magnolia grandilfora, Ligustrum quihoui, Buxus sinica, Aucuba japonica var. variegata D’Om-Brain etc. However, it seemed no harm to Platanus hispanica, Lagerstroemia indica, Koelreteria interifolia, Hibiscus syriacus, Photinia serrulata etc. The unscientific landscaping planting and management increased the damage seriously. For future urban ecological landscape construction, we must try our best to reduce the effect of natural disasters and man-made disasters on urban greening.
