城市残存鼠生态特征——Ⅰ.城市残存鼠群落特征的研究

The Ecological Character of Remnant Rodents in Urban——Ⅰ. study on the Community Character of the Urban Remnant Rodent.

本文报道在城市灭鼠达标后鼠密度很低的状态下,连续18个月对不同建筑物类型的住宅区,住房内的不同场所以及工厂、企业、宾馆的不同环境点的残存鼠群落结构进行了调查,用Shannon-weaner及pielou公式计算分析了城市残存鼠群落的物种多样性指数和均匀度。

The community character of the urban remnant rodent in the dwelling areas of different building styles and the various indoor places as well as the factories, enterprises and every environmental point of hotels was reported by the investigation of 18 successive months after attaining the urban rodent calamity free level and the rodent density keeping very low. The index of species diversity and evenness are calculated by use of Shannon-weaner & Pielou formula.
