| 摘 要： | 研究绿化树种在沿海岛屿和内陆物候差异性不仅为沿海岛屿的绿化建设和植物景观配置提供科学依据和参考,还为建设典型生态岛屿以发挥最大生态效益提供指导。本文比较了上海崇明岛和闵行地区的银杏Ginkgo biloba、乌桕Sapium sebiferum、无患子Sapindus mukurossi、紫薇Lagerstroemia indica、紫荆Cercis chinensis和栾树Koelreuteria paniculata 6种绿化树种物候的差异,结果表明,上海崇明岛的绿化树种萌芽开始和结束时间、展叶开始和结束时间比闵行平均晚10~18d,但落叶开始时间和结束时间却比闵行地区平均早15~25d,崇明岛绿化树种的平均叶寿命比内陆闵行的平均寿命短53~89d。说明两地小气候环境对6种绿化树种物候相有影响,即两地对萌芽结束时间、萌芽持续时间、落叶持续时间影响显著。

| Abstract: | Phenological differences in greening tree species are studied in order to provide landscape planning decisions with the aim of maximizing the ecological benefits of rehabilitation and greening efforts.This paper provides a comparison of the coastal island of Chongming (CM) with an inland area in the Minhang(MH) district of Shanghai.On-site investigation made phenological analysis and comparisons of six trees typically introduced for greening purposes:Ginkgo biloba,Sapium sebiferum,Sapindus mukurossi,Lagerstroemia indica,Cercis chinensis and Koelreuteria paniculata. The results showed that bud break had begun and completed ten to eighteen days later on the island than inland,as did the leaf expansion,but leaf abscission began and completed on the island fifteen to twenty-five days earlier than inland.The overall duration that the trees were in leaf on the island microclimate was fifty-three to eighty-nine days shorter than that of the inland area.The study concludes that the different microclimates and geological conditions of the two areas have significant impacts on the phonological phases of the six greening trees,in particular,the bud break completion and duration and that the impact on the duration of the leaves is highly significant. |
