【摘要】 以蜻蜓作为指标生物进行环境监测。2013年5月至2014年10月,于紫金山水榭200 m长路径进行蜻蜓种类与数量的监测调查,发现水榭地区常见蜻蜓隶属于6科16属18种,个体数量以褐斑异痣蟌最多。种类以蟌科居多,蜻科次之。研究表明,季节的温度和湿度可能是导致蜻蜓种类和数量变化的主要原因。现在城市郊区大多为人工环境,噪音和环境污染加剧等因素导致蜻蜓生活和繁殖的环境条件逐渐恶劣,从而影响蜻蜓种类和数量,人为活动影响蜻蜓在种类和数量上发生变化。更多还原

【Abstract】 Some reference for the environmental monitoring was conducted with dragonflies as indicator species. May 2013 to October 2013,monitoring survey of dragonfly species and the number were conducted in Liuhui Waterside Pavilion 200 meters long path. Common dragonfly of Liuhui Waterside Pavilion belonging to 6 families,16 genera and 18 species were found.The most number of dragonfly was Ischnura senegalensis. The most species of dragonfly was libellulids, the second was coenagrionidae. Studies indicated that the main factors effected on the species and number of dragonfly was seasonal temperature and humidity difference. In addition,city constructions lead to the suburbs of the city changed into artificial environments. The aggravation of noise and pollution also made the living and propagation environment of dragonfly becoming worse,thus affecting the species and number of dragonfly. Namely human activity was the most sensitive factor in population dynamics of local-dragonfly.更多还原
