Abstract

Jingzhou city is well-knowing for its ancient historical, massive cultural, and river system ramified. To understand the actual status of road greenery in Old Town, three typical roads, Quyuan South Road, Wude Road, and Jiang Jin Road, were sifted and divided into nine plots (Quyuan South Road, Wude Road a, Wude Road b, Wude Road c, Wude Road d, Jiang Jin Xi Road). Indexes of species abundance, Shannon-Weiner, Simpson, and Pielou were employed to dissect the road belt community. Results showed that the community diversity was higher in plant structure complicated than only shrubs arrangement. The ideal road plots were Jiangjin West Road, sections a and b of Wude Road based on the evaluation results of the above indexes and actual effects of sunshade, seasonal changes, and ecological function. The shortcomings of the investigational road uncovered the existing problems. Too much attention has been paid to the ornamental effects to lower the importance of ecological function and the utilizing comfort of citizens. Therefore, the urban road greenery should combine the environmental function and aesthetic needs, and regular maintenance management should be timely and scientific.

荆州市道路绿化现状调查与分析

荆州市以其悠久的历史、厚重的文化和纵横交错的水系而闻名。为了解老城区道路绿化的实际状况，对曲源南路、无德路、江津路三条典型道路进行筛选，划分为曲源南路、无德路a路、无德路b路、无德路c路、无德路d路、江津西路9个地块。采用物种丰度指数、Shannon-Weiner指数、Simpson指数和Pielou指数对公路带群落进行了分析。结果表明，植物结构复杂的群落多样性高于仅灌木排列的群落多样性。综合上述指标的评价结果和实际的遮阳效果、季节变化、生态功能，理想道路样地为江津西路、武德路a段、b段。调查道路的不足暴露了存在的问题。过分注重园林的观赏效果，降低了园林生态功能和市民使用舒适度的重要性。因此，城市道路绿化应将环境功能与审美需求结合起来，定期养护管理应及时、科学。
