摘要:
为研究合肥市市域范围内的生物多样性,通过实地调查结合文献资料,对合肥市境内的生物进行统计,发现现有维管束植物169科、691属、1 567种,陆栖脊椎动物98科245属424种。以县级行政区域作为评价单元,选取野生动物丰富度、野生维管束植物丰富度、生态系统类型多样性、物种特有性、受威胁物种的丰富度和外来物种入侵度6个评价指标,对合肥市6个评价单元的生物多样性现状进行评价。结果显示:巢湖市、肥西县、合肥市辖区、庐江县和肥东县的生物多样性指标(BI)值分别为33.88、32.54、32.22、31.69和31.48,处于“中”水平 (30≤BI<60),长丰县的生物多样性指数(BI)为25.07,处于“一般”水平(20≤BI<30)。最后根据评价结果,提出了合肥市生物多样性保护措施。

Abstract:
In order to study the biological diversity of Hefei, we counted the number of biology in Hefei city based on field survey and literature, and the result indicated that there were 1 567 species, 691 genera, 169 families of vascular plants, and 424 species of terrestrial vertebrates belonging to 245 genera, 98 families in Hefei. Based on the county administrative region in Hefei city, we selected six indexes, including the richness of wild animal species, the richness of wild vascular plant species, the diversity of ecosystem types, the species endemism, the richness of threatened species, and the degree of invasion of invasive alien species, to investigate and evaluate the biodiversity status of six evaluation units. The results showed that the biodiversity index (BI) values of Chaohu city, Feixi county, Hefei city District, Lujiang county and Feidong county were 33.88, 32.54, 32.22, 31.69, and 31.48, respectively, which were at the “medium” level(30≤BI<60). Nevertheless, the BI value of Changfeng county was 25.07, which was at the “general” level(20≤BI<30) according to the evaluation criteria. Finally, we put forward the biodiversity protection measures in Hefei city.
