乡土植物在广州城市园林绿化中的应用

通过对广州市园林绿化植物的种类进行调查并对其组成特点进行分析,结果表明,目前广州市园林植物种类较多,但在组成上仅一小部分植物占有优势,且乡土植物种类不多,外来物种却占有较大比例,有毒植物的种植也很普遍。在对广州地区野外植物资源状况调查的基础上,选择了具有较高观赏和应用价值的11种乔木、6种灌木和3种草本地被乡土植物,对其特性及园林用途做了简要介绍。

Application of Indigenous Plants to Urban Landscape in Guangzhou

Our extensive investigation to the landscape plants cultivated in the urban green-lands of Guangzhou city and our comprehensive assessment to the species constitution revealed that the garden plants were very rich in terms of species number but only small part of plants were highly dominant in terms of species constitution.Moreover,the indigenous plants were poorly applied,on the contrary,the alien plants took up dominant proportion and poisonous plants were also commonly introduced in Guangzhou city.On the basis of our investigation to the wild plants in Guangzhou district,we selected 11 arboreal,6 shrubby,and 3 herbal indigenous plants with high ornamental and applicable values and introduced their features and uses,so as to provide much valuable reference for the future selection and application of landscape plants in Guangzhou.
