摘要
Abstract
Biodiversity is undergoing more and more threat in the recent years.In order to evaluate the effects of biodiversity conservation in China,Red List Index (RLI) designed by IUCN (World Conservation Union) is introduced and revised to observe the rate of biodiversity loss of vertebrate and vascular plant.The results show that ascending of the RLI of vertebrate by Equal-steps indicates descending of the rate of biodiversity loss,but descending of the RLI of vertebrate by Extinction risk indicates further loss of some high Red List Categories species.RLI of vascular plant by Equal-steps and Extinction-risk all decline in some degree,indicating that the rate of biodiversity loss of vascular plant is quickened.Furthermore,RLI of vascular plant by Equal-steps declines faster than by Extinction risk,indicating that a majority of vascular plant species are facing a rising loss rate and therefore corresponding protection is necessarily enhanced.It' s not only an application but also verification of RLI at national level and the calculation results would be used as a reference for biodiversity conservation in China.关键词
