摘要
开展受威胁和濒危物种价值评估是生物多样性研究的关键问题之一。当前受威胁和濒危物种研究正处于濒危等级界定和保护优先性确定阶段,存在不同保护等级交叉管理、价值评估方法欠缺及重复性计算等多方面问题。利用IUCN濒危等级和中国特有种等级名录确定厦门市不同濒危等级物种数,在此基础上利用能值转换率和修正的中国能值/货币比率对厦门市陆域受威胁和濒危物种价值进行估算。结果显示,通过多途径整理纳入估算的厦门市陆域野生动植物物种数为1444种,其中受威胁和濒危物种数为318种;2015年厦门市物种能值价值约为3.53×10^11元,2010年约为3.08×10^11元,其中两期受威胁和濒危物种能值价值均占物种总价值的88.31%;中国特有种等级对价值贡献最大达73.25%,其次是IUCN濒危等级达23.24%。研究表明,能值评估法能够客观凸显受威胁和濒危物种价值,研究结果可为生物多样性及物种保育的管理决策提供技术支撑。
The implementation of value assessments and analysis of the effectiveness of protection of different types of threatened and endangered species has become a key issue in biodiversity research.Current research into threatened and endangered species focuses on defining the level of endangerment and determining the priority of protection,and it is subject to problems,such as cross-management of different protection levels,lack of value assessment methods,and repetitive calculations.In this study,the number of different endangered species in Xiamen was determined using the IUCN endangered grade and the list of endemic species in China.Based on this,the emergy/GDP ratio was used to estimate the number of threatened and endangered species in Xiamen City.According to the collected,summarized,and analyzed results,there are 1444 terrestrial wildlife species in Xiamen,of which 318 are threatened or endangered.The estimated emergy value of those species was found to be approximately 3.53×10^11 yuan in 2015 and about 3.08×10^11 yuan in 2010.The emergy value of threatened and endangered species in the two periods accounted for 88.31%of the total value of the species.The endemic species hierarchy in China contributed 73.25%of the emergy value,but the contribution rate of the IUCN endangerment classification was 23.24%.Research indicates that the emergy assessment method can highlight the value of threatened and endangered species in an objective manner.These results can provide technical support for decision-making in biodiversity and species conservation management.
