生物多样性价值研究再评估:基于Meta分析的启示

发布时间：2019-03-09 13:41

【摘要】：国内外已经在生物多样性价值评估方面开展了大量实证研究,但已有评估结果存在较大的差异性,增加了评估结果应用于生物多样性保护政策制定和实施的难度。采用Meta分析方法对国内外生物多样性价值研究结果进行再分析,总结已有研究的特征和趋势,分析和检验研究结果的影响因素。结果显示,评估价值类型、评估方法、评估时间、评估对象所在地的经济发展水平以及评估结果的发表类型等,都会显著影响生物多样性的人均价值量评估结果,而生物多样性的研究尺度以及文献来源对评估结果并无显著影响。建议在利用已有研究成果来评估生物多样性价值时,需要关注Meta分析所给出的评估结果差异性的来源;鉴于国内国际研究并无显著差异,在尚未开展独立价值评估的领域,可以适当借鉴国外已有研究成果。
[Abstract]:A large number of empirical studies have been carried out in the field of biodiversity value assessment at home and abroad, but there are great differences in the assessment results, which makes it more difficult to apply the assessment results to the formulation and implementation of biodiversity conservation policies. The research results of biodiversity value at home and abroad were reanalyzed by means of Meta analysis, and the characteristics and trends of the previous studies were summarized, and the influencing factors of the research results were analyzed and tested. The results show that the assessment value type, assessment method, evaluation time, the level of economic development of the target, and the type of publication of the assessment results will significantly affect the assessment results of the per capita value of biodiversity. However, the study scale of biodiversity and the source of literature had no significant effect on the assessment results. It is suggested that when using the existing research results to evaluate the value of biodiversity, we should pay attention to the source of the differences in the assessment results given by the Meta analysis. Since there is no significant difference between domestic and international research, the existing research results can be used for reference in the field of independent value assessment.
