国道104徐州段道路绿化植物多样性研究

Study on the Plant Species Diversity of 104 State Road in Xuzhou

摘要: 本文通过采用典型样方与均匀分布相结合的方法，对徐州地区国道104段绿化状况进行调查。利用丰富度指数、香农–维纳指数(Shannon-Weiner index)、Pielou均匀度指数对植物多样性进行了研究。结果表明：G104的道路绿化共有乔木25种，灌木13种，草本14种。植物种类、Shannon-Weiner 多样性指数、Pielou均匀度指数样方间存在较大的不平衡性，路段差异较大。徐州地区国道104的道路绿化只注重了乔木的种植，而忽略了灌木与草本的绿化效果。 According to the investigation with the methods of uniform distribution and typical sample, the plant species and diversity of 104 state road in Xuzhou were studied by using richness index, Shannon-Wiener index and Pielou evenness index. The results were as follows: there were 25 kinds of arbor, 13 kinds of shrub and 14 kinds of herbage in G104. There was a significant imbalance among plant species, Shannon-Weiner diversity index and Pielou evenness index in different plots. Tree planting was focused on, but greening shrubs and herbs were ignored.
