摘　　要：通过野外实地调查和查阅文献资料,在广东省肇庆市螺壳山共记录野生种子植物139科497属933种。植物区系分析结果表明,螺壳山植物物种丰富,以泛热带地理成分最为丰富。区内木本植物丰富,包括乔木258种、灌木219种、木质藤本61种。许多植物具有较高的观赏价值,但多为小密度种群。与邻近的鼎湖山自然保护区相比,螺壳山森林植物的丰富度较低,可能是长期人为干扰的结果。建议加强自然保护,促进螺壳山珍贵树种资源的可持续利用。Based on field survey, a total of 933 species of seed plants were recorded on Luokeshan, Zhaoqing city, Guangdong province, which belong to 497 genera of 139 families. The flora was dominated by the pantropic element. There were diverse woody plants, including 258 trees, 219 shrubs and 61 lianas. Many had high ornamental value in landscape, but their populations were small. By comparison with the adjacent Dinghushan National Natural Reserve, its species richness was low, which possibly due to frequent human disturbances. It was suggested to enhance conservation of natural forest for sustainable utilization of native precious trees.
