中山市小榄镇城区绿地植物调查与评价

本文对小榄镇城区绿地植物种类进行了调查与研究.调查发现,小榄镇植物种类丰富,有105科433种.其中,公园绿地和苗圃区植物种类最多,街头与街道附属绿地植物种类较单调:乔木与灌木应用较多,藤本植物应用较少:乔木花卉于公园中应用较多;人工造林的林相、林型单一.旧城区绿地严重缺乏;部分工厂、学校对绿化不重视.研究提出,合理选择绿化树种,将木兰科植物作为乡土类的重点,紫葳科、木棉科和豆科作为外来树种引进的重点;对贺榄山现存桉树、相思疏残林进行林相改造,选择樟科、壳斗科、山茶科等作为骨干树种分期、分批进行混植.最后,筛选出适合各种类型绿地应用的绿化树种.

Survey and evaluation on plant species of green land in Xiaolan Town,Zhongshan City

This paper has investigated and studied the plant species of green land in Xiaolan Town,Zhongshan City.According to the survey,garden plants in Xiaolan town are abundant and varied including 105 families and 433 species,most of which are planted in parks and nurseries.In contrast,there are much fewer street trees and road trees.Arbors and shrubberies are widely cultivated,especially efflorescent arbors are extensively planted in parks,while lianas are rarely used.Aspect and type of the artificial forest are very monotonous.There is a serious lack of green land in the old urban area.Some factories and schools do not attach importance to greening.The author points out that garden trees should be reasonably chosen,and indigenes mainly planted,such as Magnoliaceae,and in the meantime exotic species introduced,such as Bignonaceae,Bombacaceae and Fabales.The residual forest of Eucalyptus and Acacia in Yuanlan Hill should be improved by building the mingled forest,in which main trees selected from Lauraceae,Fagaceae and Theaceae will be planted together by stages and in batches.In the end,garden plants suitable for different types of green land are picked out.
