广州市公园耐湿草本植物及其造景应用

Moisture-tolerant Herbaceous Plants in Guangzhou's Parks and Their Landscape Application

选择广州市具有较长的自然式缓坡驳岸,且植物养护管理良好的6个公园为研究对象,调查其耐湿草本植物种类及其景观应用情况,分析广州公园耐湿草本植物造景的特点与存在的问题。研究表明,在调查区域内共记录有耐湿草本植物77种(含变种、变型和品种),隶属26科52属,其中一年生草本26种,多年生草本50种,蕨类1种;常用的耐湿草本植物以低矮型和中型草本为主。广州公园的耐湿草本植物应用于水边造景有以下四个特点:(1)色彩调和,展现水乡风光;(2)线条变化,增添湿地趣味;(3)适地适草,体现热带特色;(4)自然种植,创造观景效果。广州公园建设宜考虑适当增加地带性的多年生耐湿草本植物种类。
