深圳市公园绿地灌草层彩叶植物调查与分析

Investigation and Analysis of Color-leafed Plants in Shrub and Herb in Park of Shenzhen

彩叶植物对园林景观绿地具有重要的意义。通过对深圳市18个公园3种类型的景观绿地灌草层植物展开调查,得出不同环境下灌草层彩叶植物的种类,并根据相对频度、相对显著度、重要值等指标,对不同环境下灌草层植物进行分析,最后对不同类型景观绿地的彩叶植物应用进行探讨。结果显示:彩叶草、大叶红草、变叶木等彩叶植物在无郁闭度景观绿地中应用广泛,应用效果好;红背桂、金脉爵床等植物在林下景观绿地中应用广泛,应用效果好;花叶艳山姜是滨水景观绿地中应用较多的彩叶植物。

Color-leafed plants have great significance to landscape.We investigated shrub and herb plants of 18 parks in Shenzhen,which grew in three different types of landscape.The species of color-leafed plants in shrub and herb under different types of landscape were known.We analyzed the plants in shrub and herb,which grew in three different types of landscape,by relative frequency,relative prominence and relative important value,etc.Finally,the application of color-leafed plants in different types of landscape was discussed.The results showed that the color-leafed plants were widely used and had good application effect in non-canopy landscape,such as Coleus hybridus,Alternanthera dentate(Moench)Scheygr.and Codiaeum variegatum etc.;the color-leafed plants were widely used and had good application effect in understory landscape,such as Excoecaria cochinchinensis Lour.,Sanchezia speciosa Leonard etc.;Alpinia zerumbet(Pers.)Burtt et Smith‘Variegata’was one of the most widely used color-leafed plants in waterfront landscape.
