华南农业大学校园绿地自生植物研究

Spontaneous Vegetation in the Green Space of Campus of South China Agricultural University

近年来,生态园林、节约型园林建设成为城市绿化可持续发展的必由之路。为更好地在园林中利用自生植物,对华南农业大学校园绿地中自生植物的种类以及群落多样性进行调研。结果表明:全园自生植物种类丰富,共119种,隶属于42科111属,其中乡土植物占63.4%,外来植物占36.6%,入侵植物占22.9%。自生植物表现出较强的抗性和植物群落景观效果,科学利用其生长特性和群落特点,有利于形成富有特色和生态意义的园林植物景观。

In recent years the construction of ecological gardens and economical gardens has become an important way for the sustainable development of urban greening.To make better use of spontaneous vegetation in the landscape a survey was made of the plant species and community diversity of the spontaneous vegetation in the green space of South China Agricultural University.The results indicate that the spontaneous vegetation in the green space is abundant in plant species,with 119 species belonging to 111 genera and 42 families.Among the plant species the native plants accounted for 63.4%,the exotic plants accounted for 36.6%,and invasive plants accounted for 22.9%.The spontaneous vegetation is highly tolerant to stress and has a plant community landscape feature.Scientific use of the plant growth and community of the spontaneous vegetation is conducive to establishment of a unique landscape with ecological significance.
