桂林市訾洲公园植物资源调查研究

Investigation of Plant Resources in Zizhou Park of Guilin City

为了解桂林市訾州公园植物资源及景观现状,通过实地调查并查阅相关文献资料,对该公园植物组成、优势科、生活型、观赏特性、物种来源等进行分析。结果表明,园内共有维管束植物167种,隶属于74科145属,其中以豆科和禾本科为优势科;植物生活型齐全,乔木和草本占主体且常绿植物数量较多;观赏植物以观花植物为主,占植物总种数的57.5%;乡土植物97种,外来植物70种,占比分别为58.08%、41.92%;园内还有中国特有植物5种,濒危植物9种和国家重点保护植物7种。訾洲公园植物景观与其他构景要素较协调,地域特色鲜明,但仍需丰富藤本植物应用形式、增加观赏植物种类、加强宣传科普教育和采取合理的养护管理办法。以期为訾洲公园及桂林城市公园景观营建和升级改造提供参考。
