摘要:

研究园林绿化树种在盐土地上的物候特征,不仅可以为盐土地的绿化确定最佳的造林时间,还可以为植物群落的景观配置提供科学依据。本研究以上海崇明东滩湿地公园45种园林绿化树种为对象,对其萌芽和展叶物候进行了观测。结果表明:萌芽期从3月中旬持续到4月下旬,其中22种集中在3月下旬,建议造林在4月底之前完成; 展叶期从3月下旬持续到5月下旬,高峰期在4月中旬至5月上旬,可以根据树种展叶时间的早晚进行景观配置; 根据45种树种萌芽和展叶物候特征的差异,划分为4种类型,同一类型内树种具有相似的物候匹配关系,因此,在进行景观配置时,具有一定的相互替代功能。最后给出了在植树造林和树种配置上的建议。

Abstract: The phenological characteristics of landscape greening tree species on saline soils can not only determine the best afforestation time, but also provide scientific evidence for landscape configuration of plant communities. Taking the 45 landscape greening tree species in Dongtan Wetland Park of Chongming Island as the objects, an observation was made on the phenology of budding and leaf expansion. The budding period continued from mid March to late April, and 22 species budded in late March. Therefore, the afforestation was advised to be before the end of April. The leaf expansion continued from late March to late May, and the main expansion peak continued from mid April to early May. The landscape configuration of the 45 tree species could be in accord with the time of leaf expansion. According to the phonological differences, the 45 tree species were divided into four types. The trees in the same types were similar in phenological matching relationship, and thus, had certain mutual replacement function in landscape configuration. Some suggestions on the afforestation time and the configuration of tree species were put forward.
