摘要
区域生物多样性评价是不同地区生物多样性及生态环境评估的重要依据.为了解河南省柘城容湖区域两栖动物物种多样性及其时空分布格局,按照生物多样性观测标准及两栖动物的生态习性,本研究设置了10条调查样线和5个围栏陷阱,于2016-2018年每年的4月中旬、6月初和7月底进行观测研究.观测期间记录到两栖动物5种6 311只,隶属1目4科4属,其中,该区域内黑斑侧褶蛙优势度最高,北方狭口蛙的优势度最低;不同月份间比较发现,6月份观测物种个体数量最多,但Shannon-Wiener多样性指数(H')和Pielou均匀度指数(J')最低;不同生境类型下物种多样性比较结果显示,城区内J'值较高,城区外物种丰富度和H'值较高,其中河流生境下的H'值最高.总体上,受不同的栖息地类型、繁殖时期、社会经济活动与城市生态环境保护程度等因素的共同影响,河南省柘城容湖两栖动物呈现出物种多样性较低但整体分布格局相对稳定的特点.
Abstract
The evaluation of regional biodiversity provides essential insights for the assessments of the biodiversity and the ecological environment in different regions.To determine the amphibian diversity and its spatiotemporal distribution in the Ronghu Lake,Zhecheng,Henan province,ten survey lines and five fencetraps were set up in this study based on the observation standard of biodiversity and the ecological habits of amphibians,and the amphibian diversity monitoring was carried out in Mid April,Early June and Late July during 2016 to 2018.A total of 5 species and 6311 amphibians belonging to one order,four families and five genera were recorded during the observation period,with Pelophylax nigromaculatu as the dominant species and Kaloula borealis as the rare species in this sample area.Comparison analysis of the observation results among different months shown that the highest number of species individuals were observed in June whereas it had the lowest Shannon-Wiener diversity index(H')and Pielou evenness index(J').According to the analysis of the species diversity comparison among different habitat types,the higher Pielou evenness index(J')was found in the urban area,while the species richness and Shannon-Wiener diversity index(H')were higher outside the urban area.The highest Shannon-wiener diversity index(H')was in river habitat.In general,the amphibian diversity in the Ronghu Lake,Zhecheng,Henan province was low and the overall distribution pattern was relatively stable due to the interactions between the different habitat types,breeding periods,social and economic activities as well as urban ecological environmental protection.
