Study On The Relationship Between Environmental Benefit Cognition Of Reclaimed Water And Their Reuse Behavior Of Residents In Xi'an

With the rapid development of the global economy and the growing population,the sustainability of water resources has attracted more attention.With the acceleration of urbanization and industrialization,China's urban sewage discharge and sewage treatment volume have steadily increased,and the sewage treatment rate has increased linearly,but the reuse rate of recycled water has always stopped.Existing studies have generally focused on the influence of macro factors,ignoring the internal attribution of micro-subject cognition and psychological factors.As a direct use subject of recycled water reuse,urban residents' cognitive and behavioral choice have become the fundamental determining force.In view of this,this study starts from the microscopic perspective,combined with the characteristics of recycled water reuse,taking the urban residents' awareness of the reclaimed water environment benefit and the willingness to reuse behavior as the starting point and the foothold,respectively,and constructing the path of individual cognition and behavioral willingness.The theoretical model explores the intrinsic link between the perception of urban residents' reclaimed water environmental benefits and their reuse behavior.Based on the survey data,the SEM model test shows that:(1)The recognition of the environmental benefits of reclaimed water has a significant impact on the reclaimed water reuse behavior of urban residents in China.Among them,resource benefit cognition and environmental improvement benefit cognition are significantly positively correlated with reuse behavior,while health risk benefit cognition has a negative impact on their reuse behavior;(2)The improvement of resource benefit recognition and environmental improvement benefit recognition can weaken the perception of health risk benefits to some extent,and thus promote the corresponding reuse behavior;(3)The residents' reclaimed water reuse behavior intention has a partial mediation between its environmental benefit cognition and reuse behavior choice;(4)The level of education and incomehas a significant regulatory effect on the reuse of reclaimed water.Increasing the popularization and information disclosure of reclaimed water reuse,and the supervision of water quality,so as to weaken the public's risk perception and guide its behavior,which will be of great significance to solve the promotion problem of reclaimed water reuse in China.The research findings of this paper can help the government to clarify the impact mechanism of urban residents' reclaimed water environmental benefits on their willingness to reclaimed water reuse behavior,and explain and verify the gap between “cognition-behavior” in the field of reclaimed water reuse.Thereby guiding the reclaimed water reuse behavior,providing a reference for promoting the sustainable development of society and the construction of socialist ecological civilization.
