Abstract:

In order to provide a scientific basis for upgrading the level of a nature reserve (NR) and selecting the appropriate management type, the conservation priority of NRs should be identified. How to objectively identify conservation priorities has become a key problem. We propose a mathematical method to comprehensively assess species diversity conservation values by comparing existing evaluation indexes and methods, consulting experts and processing indexes quantitatively. This evaluation method includes the following indices: the wild plant diversity conservation value index; wild animal diversity conservation value index; rare and endangered wild plant diversity conservation value index; and the rare and endangered wild animal diversity conservation value index of a NR. Meanwhile, 39 NRs in North China Warm Temperate Region and 67 NRs in Northeast China Temperate Region were selected as case studies to verify methods, based on species diversity data of the NRs. The evaluation results revealed that some provincial NRs could be recommended for an upgrade to national NRs, due to high species diversity conservation values, including the Nandagang Wetland and Liaohe River Source NRs of Hebei, Wuling Mountain NR of Beijing in the North China Warm Temperate Region, the Jingpo Lake, Dajia River, and Cuibei Wetland NRs of Heilongjiang in the Northeast China Temperate Region. The computation method showed a great advantage in comparing species (various groups) diversity conservation values for different NRs and determining the conservation priority sequence. Moreover, there were significant differences in the species diversity conservation value of NR among different natural conservation geographical areas, and types of NRs.
