野生动物价值影响因素的构成及评价

摘要

From May to June,2017,we sent questionnaires to the relevant staffs of wildlife protection by mail and field inter-view,and obtained 480 valid questionnaires.The model of the influence mechanism of wildlife value was constructed on basis of the investigation result and the influence factors of wildlife value.In order to analyse how these factors impact on the wildlife value,the structural equation model(SEM)was applied.The value of wildlife is influenced by factors like its own resource endowment,policy intervention,human needs and public cognition.Among all these factors,its own resource endowment is the primary one to the value of wildlife,followed by human needs,policy intervention and public perception. The representativeness and scarcity of species can be the best explanation of the natural endowment of wildlife.The function of ecological service of wildlife can be the best explanation of the value of wildlife.%2017年5—6月份,利用问卷邮寄、实地访谈的形式,向野生动物保护相关工作人员发放调查问卷,获得480份有效调查问卷;依据调研结果和野生动物价值影响因素,构建了野生动物价值影响机理模型;利用结构方程模型,分析了各影响因素对野生动物价值的影响.结果表明:野生动物价值受自身资源禀赋、政策干预、人类需求、公众认知的共同影响,自身资源禀赋是影响野生动物价值的首要因素,其余依次为人类需求、政策干预、公众认知;对于自身禀赋潜变量,物种的代表性和稀有性的贡献程度大于其他7个观测变量;对于野生动物价值潜变量,生态服务功能贡献程度大于其他观测变量.
