摘要
以扬州瘦西湖古典园林为研究对象,将植物群落类型划分为3种:以建筑景观为主的庭院植物群落,沿湖面主环路的湿地植物群落和陆地植物群落。同时应用植被生态学调查方法调查树种配置,统计生长指数和种间联结关系。结果表明,出现在瘦西湖主要群植园林中的木本植物有67种,树木健康状况总体良好,园林群落中成显著正联结关系的种对包括:旱柳-桃、朴树-乌桕、银杏-乌桕、马尾松-榉树、红枫-鸡爪槭、琼花-金钟花、桂花-朴树、黄杨-紫薇等19对,而榉树-三角枫、桧柏-木芙蓉、旱柳-黄杨、白玉兰-火棘、枫杨-红枫、乌桕-桃、鸡爪槭-棕榈、银杏-日本樱等12对为负联结的种对,研究结果可为园林植物的优化配置提供生态学依据。
The Shouxihu lake classical gardens in Yangzhou city were selected as study cases in the paper,plant communities were classified into 3 site categories： plant communities of the small yard with constriction,marsh plant communities along the main circuit of lake surface and terrestrial plant communities.The sampling method of Vegetation Ecology was employed in the paper to investigate species composition and tree health index,and species association was accounted as well.The results showed that there were 67 woody species reported in samples,and the health situation for total trees could be evaluated as good.Sixteen species-pairs showed a significant positive correlation such as Salix matsudana-Prunus persica,Zelkova schneideriana-Sapium sebiferum,Ginkgo biloba-Sapium sebiferum,Pinus massoniana-Zelkova schneideriana,Acer palmatum-Acer palmatum Thunb,Viburnum macrocepharum-Forsythia viridissima,Osmathus frograns-Celtis Petrandra;but another 12 species pairs showed negative correlation such as Zelkova schneiderian-Acer buergerianum,Sabina chinense-Althaea rosea,Salix matsudana-Buxus sinica,Magnolia denudate-Pyracantha fortuneana,Pterocarya stenoptera-Acer palmatum f.rubrum,Sapium sebiferum-Prunus persica,Gingko biloba-Prunus yedoensis.This conclusion provides an ecological understanding for planting design in gardens.
