摘要
对云南省84个县(市)双团棘胸蛙(Paa yunnanensis)地理分布进行了全面调查。基于历史记录与本次调查结果,采用地理信息系统,制作了云南双团棘胸蛙地理分布图。结果表明,双团棘胸蛙在云南广泛分布于迪庆州以外的15个州(市)71个县(市),分布海拔为1400～2600m,年平均气温为11.54～18.50℃。根据双团棘胸蛙分布受海拔和年平均气温限制的特点,采用DIVA-GIS5.2软件,得到云南省双团棘胸蛙可能分布区图。该图可以预测双团棘胸蛙在云南的潜在地理分布,为在云南对该物种的深入研究和有效保护提供了基础数据。
A complete survey on geographic distribution of Paa yunnanensis was conducted in 84 counties of Yunnan Province. The distribution of this species was mapped with GIS tools, based on both the data obtained from this sampling and derived from literatures. The result shows that P yunnanensis is widespread in 71 counties of 15 prefectures except Diqing prefecture of Yunnan Province. The altitudes and mean annual temperatures for P yunnanensis distribution were recorded as 1400-2600 m and 11.54-18.50℃, respectively. Based on these features ofP. yunnanensis, two possible distribution maps of the species were mapped through software DIVA-GIS 5.2. These maps may forecast the potential distribution of P yunanensis in Yunnan, providing basic data necessary for further study and protection of P. yunnanensis.
