The policies and research institutions on protection and utilization of biodiversity in Pu'er City were introduced. At the last, we analyzed the deficiencies in the conservation and utilization of biodiversity in Pu'er City and proposed the relevant measures to strengthen protection and utilization of biological diversity in the future.展开更多
