摘要：
目的分析荆州城市公园植物群落物种多样性,为荆州及周边地区城市公园绿地规划和植物多样性保护提供参考依据.方法采用典型样方法,对荆州市7个城市公园选取235个样方开展植物多样性现状调查,分析其群落特征.结果荆州城市公园植物物种丰富,共有植物96科248属351种,植物群落优势种明显,植物多样性总体趋势依次为:灌木层,乔木层,草本层,但各公园之间又有差异,以中山公园和荆襄河湿地公园为最高;植物多样性指数大小依次为:综合公园,带状公园,专类公园.结论荆州城市公园植物群落物种组成较为丰富,物种多样性较高,但专类公园植物单一性较高,故选择适宜的植物品种,增加乡土植物的运用,提高群落的稳定性.
Objective The species diversity of plant communities in Jingzhou city park was analyzed,which could provide reference for green space planning and plant diversity protection of city parks in Jingzhou and surrounding areas.Method With the typical sample method,235 sample plots were selected from 7 urban parks in Jingzhou city to carry out the survey on the status of plant diversity,and the community characteristics were analyzed.Result Jingzhou city park is rich in plant species,with 351 species of 248 genera and 96 families,and the dominant species of plant community are obvious.The order of overall trend of plant diversity is shrub layer,arbor layer,herb layer,but there are differences between parks.Zhongshan Park and Jingxiang River Wetland Park are the highest;Plant Diversity Index,from high to low,is in order of Comprehensive Park,Strip Park,Specialized Park.Conclusion The plant community of Jingzhou city park is rich in species composition and high in species diversity.However,the plant monotony in special park is high,so the selection of suitable plant species will increase the use of native plants and improve the stability of the community.
