绿地植物多样性调查研究——以明光市公园为例

Survey Study on Plant Diversity of Green Space——A Case Study of Urban Parks in Mingguang City

本文通过明光市公园绿地植物的调查,分析了公园绿地植物的种类构成。结果表明,明光市公园绿地共有植物74科、155属、213种;公园绿地植物以乡土树种为主,植物群落结构比较稳定;常绿物种远少于落叶物种;在园林树种配置上,部分公园冬季景观单调、重复,缺乏主题特色。从公园绿地植物物种的来源、丰富度指数、多样性指数及均匀度指数入手,分析了公园绿地植物存在的优势和问题,提出公园绿地植物的应用和绿地系统的建设方向,以期为公园绿化以及绿化管护水平提升提供参考。

In this paper a survey was made on the green space plants in parks in Mingguang City and the species composition were analyzed. The results showed that there are 213 plant species belonging to 155 genera in 74 families in the parks. The plant species of the park green space were mainly indigenous and the plant community structures were stable with evergreen species much fewer than deciduous species. In terms of tree species allocation, some parks had monotonous and repetitive winter landscape and lacked thematic features. An analysis was made on the advantages and problems of the plants in the park green space from aspects of sources of the plant species, species richness index, diversity index and evenness index. Some suggestions regarding application of green space plants and construction directions of the green space system were put forward in order to provide reference for promoting park greening and greening maintenance.
