广州市公园耐湿草本植物及其造景应用

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。

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

Six parks with good plant maintenance and management in Guangzhou were investigated. There were long natural gentle slope revetments in the parks. The article investigated the moisture-tolerant herbaceous plants of the parks, summarized their landscape application, then analyzed their landscape characteristics and existing problems. The results showed that, within investigation area, a total of 77 moisture-tolerant herbs belonging to 52 genera in 26 families were recorded, 26 of which were annuals, 50 of which were perennials, and left was fern. The mainly common moisture-tolerant herbs in Guangzhou’s parks were the low and middle herbs. The characteristics of moisture-tolerant herbs landscape application to Guangzhou’s parks as follows: ① Reconciling the color of plants, showed the water scenery; ② Using the varied lines to make the wetland more interesting; ③ Right place, right grass, reflecting the tropical characteristics; ④ Planting naturally and creating a view effect. Appropriate increase in native perennial moisture-tolerant herbs species should be taken into consideration in the construction of Guangzhou’s parks, and the popular science about the moisture-tolerant herbs should be strengthened.
