苏州市高中校园植物多样性调查分析

摘要

通过对苏州市3所高中校园植物种类、数量的调查,分析了校园绿化植物的应用频率和物种丰富度。结果表明：这些高中校园共有144种植物,隶属于65科131属,其中乔木31种,占21.5%;灌木37种,占25.7%;草本73种,占50.7%;藤本3种,占2.1%。人工栽培的绿化植物92种,占植物总数的63.9%;杂草51种,占35.4%,其中狗牙根（Cynodon dactylon）、马尼拉草（Zoysia matrella）为主要杂草种。整体上校园植物资源丰富,但结构相对简单,布局不合理,建议增加植物种类,提高美化效果。%In this paper,the auther made a full investigation of the campus plants in 3 high schools of Suzhou City,analyzed the plants in terms of planting frequency and species richness.The results showed that there were 144 species of plants in the schools,belonging to 65 families,131genera,among which 31 species of arbors accounted for 21.5%,37 species of bushes accounted for 25.7%,73 species of herbs accounted for 50.7%,and 3 species of lianas accounted for 2.1%.92 species of green plants were cultivated,accounting for 63.9% and 51 species of weeds accounted for 35.4% of the total number of plants,among which,Cynodon dactylon and Zoysia matrella were main weeds.The plants are rich in resources on campus as a whole,but the plant structure is relatively simple and the distribution is irrational.It is suggested to increase plant species,improve the effect of landscaping.
