Abstract: In order to protect the rare animal Nomascus nasutus and the local biodiversity,Guangxi has implemented the project on construction of cross-border biodiversity corridors.By summarizing the construction of cross-border protected areas at nation and abroad,there is some suggestion for the problems existing in the construction of cross-border biodiversity corridors in Guangxi:(1) For enhancing the communication between cross-border countries or regions,and protection of biodiversity,it need explore more scientific cross-border cooperation mechanisms;(2) Explore and promote more alternative livelihoods;(3) Implement and create other domestic cross-administrative protected areas or biological corridors in Guangxi.
