| 为明晰乡土植物在珠三角省立绿道的应用，对沿线绿道进行样方调查分析，结果表明：（1）珠
三角省立绿道共有乡土植物 147 种 , 生活型种数数量排序为乔木 > 灌木 > 地被，不同绿道类型，其植物种
数丰富程度及苗木使用数量上总体呈郊野型 > 都市型 > 生态型；（2）在品种应用方面，充分考虑到珠三角
的气候特点、植物的生态习性和主要观赏属性，乔木层以常绿的地带性树种为主，在使用频度和数量上占
优势；灌木层则以观赏性状更优秀的植物品种为主；草本地被层则观赏性和适生性兼顾的植物品种应用更
广泛；（3）品种的主要观赏属性与绿道类型存在一定关系，都市型绿道使用品种偏向景观，生态型绿道使
用品种偏向经济；（4）空间结构与植物组团上，以乔木为主体，多种生活型、多植物组成的复层林结构占
绝大部分，以高大乡土树种为优势种构成的植物组团，在各类型的绿道应用中占有明显优势。 |

| Abstract: |
| Base on site quadrat survey of provincial greenway in Pearl River Delta (PRD), this paper analyzed the
application of indigenous plants in greenway. The result showed that: (I) 147 indigenous plants were found in greenway.
According to biotype of plants, the number of the tree was the largest, followed by shrub and ground-cover. The number
and species richness of suburbs type greenway way was largest, followed by urban and ecotype greenway. (II) The
application of plants has close relations with plants’ ecological habits, ornamental attributes and climate characteristics
of PRD. On the use frequency and quantity, indigenous evergreen trees were the dominant species in arborous layer.
Ornamental shrubs were more common in shrubs layer. Ornamental ground-covers with strong resistance were used
more widely. (III) There was a certain relationship between Plants’ ornamental characteristics and greenway types.
Urban greenway pays more attention to the ornamental effect of the plant. Conversely, the cost was always a chief
concern during the construction of ecotype greenway. (IV) Considering spatial structure, the multi-storied structure
composed of plants from a variety of life forms was most common. The plant groups composed of tall indigenous tree
species had obvious advantages in the application of various types of greenway. |
