珠三角地区几种耐荫耐旱乡土地被植物的园林应用

通过在珠三角地区的广州白云山、肇庆鼎湖山、深圳梧桐山、惠州南昆山、东莞银屏山、东莞水濂山等6处选取样方进行实地调查，并采用线性加权综合法数学模型对珠三角地区野生地被植物作综合评价。结果表明，依据植物的生活型、生境、高度等特性初步确定该地区乡土地被植物70种，重点推荐紫金牛Ardisia japonica、东方紫金牛Ardisia squamulosa、马蓝Strobilanthes cusia等8种乡土耐荫耐旱地被，其在东莞植物园的配置应用实践中，均表现出极好的耐荫性和耐旱性，且扩繁较易。

Landscape Application of Several Native Groundcover Plants with Shade and Drought Tolerance in Pearl River Delta

Twelve sample plots from Guangzhou Baiyun mountain, Zhaoqin Dinghu mountain, Shenzhen Wutong mountain, Huizhou Nankun Mountain, Dongguan Yinping mountain and Shuilianshan were setting up, comprehensive assessment of native ground cover plants in sample plots were surveyed by linearity weighted integrative method of mathematical model. According to live form, habitat and height of plant, 70 species of native wild groundcover plants were selected for application to landscape, 8 species native groundcover plants with shade and drought tolerance were especially introduced, such as Ardisia japonica, Ardisia squamulosa, Strobilanthes cusia. In application practice, they grew very well in Dongguan Botanical Garden.
