永川区道路林带植物多样性研究

On Plant Diversity of Road in Yongchuan Region

通过对永川新、老区主要道路绿地植物进行详细调查,分析其道路林带的群落生长型、空间结构、物种多样性指数等,结果表明:道路林带植被类型以常绿阔叶林为主,群落垂直层次以一层结构和三层结构为主,水平结构以单一式为主;道路绿地植物的多样性发展不均衡,新城道路绿地木本植物多样性较好,老城偏低;对道路植物物种丰富度与景观美学之间的关系进行了探讨,得出道路景观美景度随物种丰富度增加而升高,最后趋于稳定.

Through investigation of the greenbelt plant of the main street in Yongchuan region,the community growth form,space structure,species diversity index of the forest road have been analyzed in this paper.The results show that the evergreen broad-leaf forests are the main vegetation types.The one-layer structure and the three-layer structure are the main vertical hierarchy and the unitary form is the main horizontal structure.With the uneven development of the plant diversity,the woody plant diversity of the new metropolitan area is higher than the old.The beauty of the landscape with road species richness increased gradually improved finally tends to be stable.
