摘  要:
[目的]为商城肥鲵的保护工作提供理论依据。[方法]通过对覆盖商城肥鲵分布区全境的8条溪流中环境变量和种群状况的调查,分析该种对生境的选择特点。[结果]在周边植被状况较好、宽度5~6 m的溪流中商城肥鲵种群状况相对更好,面积较大、较深的水潭中种群更加健康。尽管最佳生境中成体数量最高,但亚最适生境中的幼体数量远高于最适生境。这说明商城肥鲵存在种内竞争导致幼体迁移的现象,对于物种保护是有利的。[结论]该研究表明对商城肥鲵的保护工作中减少人为干扰和营造良好的植被环境是非常必要的。

摘  要:
[Objective]To provide theoretical basis for protection of Pachyhynobius shangchengensis. [Method]Through investigating the population ecology of Pachyhynobius shangchengensis in eight streams and evaluating its relationship to potential habitat factors,such as vegetation,altitude,stream width,puddle size and water depth. [Result]The results showed that vegetation in good condition and stream width of about 5-6 m is suitable for salamander,altitude,puddle size and water depth are not significant correlated to Pachyhynobius shangchengensis population status. [Conclusion]These suggest protection of vegetation on the habitat and reducing human interference are necessary for Pachyhynobius shangchengensis protection work.
