【摘要】 对野生植物进行调查研究，筛选出具有观赏价值的种类，对丰富城乡绿化植物具有一定意义。本研究采用线路调查法对广东电白区进行野生植物调查统计，共有1 101种野生植物；采用综合评价法对其进行评价，按观赏特性拟定1～5分的评分标准，保留4分及以上的植物种类，共筛选出662种野生观赏植物进行分析。结果显示：电白区野生观赏植物662种(含种下等级),隶属于151科401属，其中蕨类植物22科26属39种，裸子植物4科5属8种，被子植物125科370属615种。按生活型划分，观赏乔木类216种，灌木类149种，草本类173种，藤本类85种，蕨类39种。按观赏类型分类，观花、观果、观叶分别为359种、174种和362种。按园林用途分类，行道树类73种，庭荫树类23种，垂直绿化类29种，地被植物类20种，室内观赏植物类25种。对电白野生植物的保护性开发不仅有利于丰富园林景观，更对物种自身的优化与发展具有重要意义。更多还原

【Abstract】 Conducting surveys on wild plants and selecting species with ornamental value is significant in enriching plant diversity in urban and rural greening. In this study, a survey was conducted on wild plants in Dianbai District of Guangdong Province using line transect method, with a total of 1,101 species recorded.The 1,101 species were evaluated using the comprehensive analysis process, and a scoring system of 1 to 5 points was proposed based on their ornamental characteristics.Plants scoring 4 points or higher were retained, out of which 662 wild ornamental plants were selected for analysis.The results showed that there were 662 species of wild ornamental plants in Dianbai District, belonging to 151 families and 401 genera, including 39 species in 26 genera across 22 fern families, 8 species in 5 genera across 4 gymnosperm families, and 615 species in 370 genera across 125 angiosperm families.Classified by life types, there were 216 species of ornamental trees, 149 species of shrubs, 173 species of herbs, 85 species of vines and 39 species of ferns.Classified by ornamental types, there were 359 species of flowering plants, 174 species of fruit-bearing plants and 362 species of foliage plants.Classified by gardening use, 73 species could be used as street trees, 23 species as shade trees, 29 species as vertical greening plants, 20 species as ground cover plants and 25 species as indoor ornamental plants.The protective development of wild plants in Dianbai District is not only conducive to the enrichment of landscape, but also of great significance to the optimization and development of the species.更多还原
