Methods of on-site investigation and data collection were used to study landscape plants in 10 parks of Chengdu.The characterics of application and improvement suggestions for landscape plants in each place were analyzed from the aspects of plant species, living form, orna-mental features, rare or endangered and toxic type and so on.This article tried to offer a proposal for improving application of landscape plants. The results indicated that:there were plentiful species in Chengdu parks which belong to 331 genera, 134 families, and 437 species;there were a lot of flowers and fruits throughout the year and flowering plants were everywhere.But some types of plants were used fewer such as vines, a-quatic plants, rare and endangered plants and color-leafed plants, the toxic landscape plants were used commonly.So some suggestions were pro-posed such as the wetland space plant landscape could be richer, the utilization efficiency of the vertical space should be improved, color-leafed plants could be planted more than ever, the natural education activities should launch plentifully.%采用实地调查与查阅文献相结合的方法,对成都市内10个公园的绿地植物进行调查,从植物种类、生活型、观赏特性、珍稀濒危、毒性等方面,及其在各公园绿地中所占的比例、应用、分布,讨论园林植物在公园内的应用特点以及改善建议.结果表明:成都市公园绿地植物种类丰富,共有园林植物437种,隶属于134科、331属;一年四季花果不断,观花植物应用较多,某些类型植物(藤本、水生、珍稀濒危、秋色叶植物)应用种类较少;有毒植物普遍应用.提出丰富湿地植物景观,提高垂直空间利用效率,增加彩色叶植物在公园内的应用,珍稀濒危和有毒植物应增加标志牌,开展丰富的自然教育活动等建议.
