摘　　要：为探讨园林植物的应用是否符合地区的绿化特色和气候,从区系地理学的角度调查并分析韶关学院校园园林植物的种类及地理区系成分.结果表明:韶关学院(校本部)校园主要园林植物共有181种(包括亚种和变种),隶属于66科133属.校园园林植物中被子植物占绝对优势,裸子植物数量较少,仅10种.植物优势科和优势属分别是棕榈科、榕属.从科、属、种三水平进行的地理区系成分分析均显示韶关学院校园园林植物以热带性质占优势.此外,乡土植物共有121种,占总种数的66.85%,外来植物共有60种,占总种数的33.15%,乡土、外来植物比约为2∶1.校园内种植有国家重点保护植物5种.根据调查结果,提出了构建具有粤北特色的校园园林绿化应进一步丰富植物的类型,优势科属需进一步优化,适当增加耐寒植物,同时也可以考虑引种一些粤北珍稀濒危植物.To explore that whether the application of landscape plants accords with the regional planting characteristic and climate, the species and flora composition of landscape plants in Shaoguan University were investigated and analyzed from the floristic geography angle. The results showed that there were 181 species （including subspecies and varieties）, belonging to 66 families and 133 genera in Shaoguan University （Headquarters）. Angiosperms dominated in the campus, gymnosperms were less, and there were only 10 species. The dominant family and genus of landscape plants were Palm and Ficus. The landscape plants had obvious tropical characteristics by analyzing of the floristic geographical elements at three levels （family, genus, and species）. In addition, there were 121 native plants which accounting for 66.85% of the total species, and there were 60 alien plants which accounting for 33.15% of the total, the ratio of native plants to alien plants was about 2：1. There were also five national key protected plants in the campus. Based on the above results, the suggestions of constructing campus with Yuebei landscape characteristics were proposed.
