摘要
为探讨广州城市绿地彩叶植物种类及应用状况,对广州市主要城市公园、市民广场、道路绿化及居民区等城市绿地214个样地展开调查.结果表明：广州城市绿地彩叶植物较为丰富,共有49科76属90种,其中新叶有色和老叶有色植物各20种、常色叶植物14种、斑色叶植物30种、双色叶植物6种.广州城市绿地重视彩叶植物应用,102个样地中彩叶植物达到6～10种,14个样地中彩叶植物达15种以上;公园次生林和生态风景林样地中,观赏价值较高的常色叶、斑色叶和双色叶植物较为稀少,而这3类植物在公园景观群落、交通绿岛、居民区和市民广场等城市绿地中较为丰富.广州城市绿地常色叶、斑色叶和双色叶彩叶树种较为匮乏,因此建议加强该类彩叶树种资源的引进、开发和利用,同时也要加强乡土彩叶植物资源的开发利用.
To survey the species and application of colored-leaf plants in Guangzhou urban green spaces, 214 sites from Guangzhou urban green spaces including urban parks, public squares, roads and residential areas were choosen. The results showed that abundant colored-leaf plants were found in all sites with 49 families, 76 genera, and 90 species, in which 14 species belonged to ever-colored-leaf plants, 30 species belonged to spot-colored-leaf plants, 6 species belonged to double-colored-leaf plants and each 20 species belonged to new and old leaf colored-leaf plants. The colored-leaf plants were attached great importance in Guangzhou urban green spaces, where 6-10 species colored-leaf plants were observed in t02 sites and more than 15 species colored-leaf plants were observed in 14 sites. Few ever-colored-leaf, spot- colored-leaf, and Double-colored-leaf plants with high ornamental value were found in secondary forest and ecological landscape forest, however, they were abundant in landscape communities, public squares, roads and residential areas. Ever-colored-leaf, Spot-colored-leaf, and double-colored-leaf arbors were lacked in Guangzhou urban green spaces, so the introduction, exploitation and utilization of these colored-leaf arbors and native colored-leaf plants should be applied in future.
