摘要
本文以三江平原湿地为研究对象,选定湿地了解程度、湿地环保关心程度等十一个居民生态认知指标,基于动态因子分析和空间自相关性,提取居民生态认知公因子,将时空维度纳入居民生态认知分析,分析其动态变化特征,建立基于居民生态认知的WTP空间滞后模型,进一步探究生态认知对湿地非使用价值的影响.研究结果表明:1)从时间层面来看,居民生态认知中的湿地生态功能因子正向动态变化特征明显;2)从空间层面来看,居民生态认知的空间相关性在增强,呈正相关关系,距离三江平原湿地越近的区域集聚程度越强,且整体趋势向好;3) WTP空间滞后模型更善于从空间尺度反应居民生态认知对WTP的作用关系,得出2007年、2011年、2014年三江平原湿地的非使用价值分别为29.48亿元/年、36.44亿元/年、37.49亿元/年.研究结果将为湿地非使用价值研究提供新思路,也为相关生态环境政策的制定提供参考依据.
This paper takes the Sanjiang Plain wetland as the research object,selects the ecological awareness index of eleven residents,such as the degree of wetland understanding and the degree of environmental protection of the wetland.Based on the dynamic factor analysis method and spatial autocorrelation,the population ecological common factor is extracted and the time and space will be selected.Dimensions are incorporated into the analysis of residents’ ecological cognition,and their dynamic characteristics are analyzed.At the same time,the WTP spatial lag model is established to further explore the impact of ecological cognition on the non-use value of wetlands.The results show that:1) From the perspective of time,the dynamic characteristics of wetland ecological function factors in residents’ ecological cognition are obvious;2) From the spatial perspective,the spatial correlation of residents’ ecological cognition is increasing and positively correlated.Relationship,the closer the Sanjiang Plain wetland is,the stronger the concentration is,and the overall trend is better.3) The WTP spatial lag model is better at reflecting the interaction relationship between residents’ ecological cognition and WTP from the spatial scale,and constructing the ecological cognition based on residents.The WTP space lag model shows that the non-use values of the Sanjiang Plain wetlands in 2007,2011 and 2014 were 2.948 billion yuan/year,3.644 billion yuan/year,and3.749 billion yuan/year,respectively.The research results will provide new ideas for the study of non-use value of wetlands,and also provide reference for the formulation of relevant ecological environmental policies.
