摘要
生活污染治理是生态脆弱区宜居性的突出短板,揭示其治理效果及影响效应对提升生态脆弱区环境可持续性、改善居民福祉具有重要价值。本文以三江源地区为典型案例,基于1,159户家庭问卷调查数据,剖析生态脆弱区生活污染治理设施配置状态、运行效果的居民感知及其与宜居性的内在关联,采用结构方程模型测度固废与液废治理的居民感知对宜居性的影响效应,并通过二元逻辑斯蒂回归模型估计不同群体及地理区位下影响效应的异质性。结果表明:①三江源地区居民对日常生活产生的固废与液废污染治理满意度分别为57.81%和55.31%,半农半牧型、农牧工兼业型家庭相较于纯农、纯牧型家庭对生活污染治理的感知更满意;②生活污染治理对三江源地区居民宜居性具有显著影响,且生活固废治理的影响强度高于液废治理,生活垃圾转运频率、生活垃圾处理方式、户厕形式和生活污水治理方式是最显著的影响因子;③在不同聚落规模、区位和海拔下,生活污染治理感知对宜居性的影响具有显著差异,小规模、偏远型、高海拔聚落的农牧民对生活垃圾治理设施配置的宜居性反馈更敏感。研究发现可为增强村镇环境基础设施配置有效性、精准提升生态脆弱区人居环境品质提供科学参考。
Domestic pollution management is a prominent constraint in the livability of ecologically fragile areas,and revealing its impact effects is an important part of enhancing environmental sustainability and improving the well-being of the residents.This paper takes the Three River Source Region as a typical case,based on the questionnaire survey data of 1,159 households,analyzes the residents'perceptions of the configuration status and operation effect of the domestic pollution management facilities in ecologically fragile areas and the intrinsic correlation between them and livability,adopts the structural equation modeling to measure the influence effect of the residents'perceptions of the solid and liquid wastes management on livability,and uses binary logistic regression model to estimate the heterogeneity of influence effects in different groups and geographic locations.The results indicate:(1)The satisfaction level of residents in the study area with the pollution management of solid and liquid wastes generated in daily life is 57.81%and 55.31%,respectively,and semi-agricultural and semi-pastoralist and agricultural and pastoralist-industrial households are more satisfied with the domestic pollution management compared with purely agricultural and pastoralist households.(2)Domestic pollution management significantly affects residents'livability in this regon,with solid waste management exerting a stronger influence than liquid waste management,domestic waste transfer frequency,treatment method,the form of household latrine,and the modes of domestic liquid waste management are the most significant impact factors.(3)The impact of residents'perceptions of domestic pollution management on livability varies significantly across settlement scales,geographic locations,and altitudes,with farmers and herders in small,remote and high-altitude settlements more sensitive to livability feedback on the configuration of domestic waste management facilities.The findings provide scientific policy reference for enhancing the effectiveness of rural environmental infrastructure configuration and accurately upgrading the quality of living environment in ecologically fragile areas.
