广东石油化工学院校园植物种类多样性调查

Investigation of Plant Species Diversity on Campus of Guangdong University of Petrochemical Technology

为了解广东石油化工学院校园植物的种类构成,经对官渡和西城校区的维管植物资源进行实地调查,并对两校区的乔、灌木类植物进行比较分析。结果表明:校园内共有维管植物112科294属400种,包括蕨类植物11科14属15种,裸子植物5科7属7种,被子植物96科273属378种;校园内有外来入侵植物68种,其中菊科(Asteraceae)、豆科(Fabaceae)和大戟科(Euphorbiaceae)入侵植物最为常见;西城校区植物4种生活型的种类均多于官渡校区。总体而言,广东石油化工学院校园植物资源较丰富,需要特别警惕的是外来入侵植物较多(占调查总种数的17%),不利于校园植物多样性的发展。

To reveal the plant species composition of Guangdong University of Petrochemical Technology,the campus vascular plant resources in Guandu and Xicheng campuses were investigated by on-the-spot investigation method.The study compared the arbor and shrub plants in these two campuses.The results showed that:(1)There were 400 vascular plants belonging to 294 genera in 112 families,including 15 pteridophytes belonging to 14 genera of 11 families,7 gymnosperms belonging to 7 genera of 5 families and 378 angiosperms belonging to 273 genera of 96 families.(2)There were 68 exotic invasive plants in the campus,among them,Asteraceae,Fabaceae and Euphorbiaceae were the most invasive families.(3)The 4 life forms of plants in Xicheng Campus are more than those in Guandu Campus.In general,Guangdong University of Petrochemical Technology is rich in plant resources.What needs exceeding vigilance is that there were many exotic invasive plants(accounting for 17%of the total investigated species),it is not conducive to the development of plant diversity on campus.
