农村居民生活垃圾治理支付意愿影响因素研究——以福建省为例

农村生活垃圾治理是实施乡村振兴战略的重要任务,也是完善农村人居环境的重要内容。本文以福建省九地市的458户微观数据为例,采用二元Logistic模型进行回归分析,结果表明:受访农户中有92.36%愿意支付生活垃圾治理的相关费用;环保认知和生活垃圾清理频率在1%的显著性水平上正向影响生活垃圾治理支付意愿;受教育程度和到垃圾囤放点的距离在5%的显著性水平上显著正向影响生活垃圾治理支付意愿;年龄、家庭人口数和对村委会的评价负向影响支付意愿。鉴于此,可通过加强宣传教育力度、完善相关配套设施和健全监督制度来提高农村居民生活垃圾治理的支付意愿。     

绿色认知对消费者参与社区支持农业(CSA)意愿的影响——基于感知价值的中介效应

为提升消费者参与意愿，推进社区支持农业(CSA)的本土化发展，基于820份消费者调查问卷，通过构建多元回归模型对绿色认知对消费者参与CSA意愿的影响，以及感知价值在绿色认知和消费者参与CSA意愿之间的中介效应进行了研究，结果表明：1)农业污染认知、绿色农产品认知和绿色政策认知对消费者参与CSA的意愿均具有正向显著影响，其中，绿色农产品认知的影响最明显。2)功能价值、服务价值和环境价值在农业污染认知、绿色农产品认知、绿色政策认知和消费者参与CSA意愿之间均具有正向显著中介作用，其中，功能价值的中介效应值最高。因此，应促进多元主体协同发展，这不仅能够提高消费者的绿色认知水平，促使其形成绿色消费意识，增强其参与CSA的主动性，而且还能够促使生产者完善CSA农场的经营管理，并使其与消费者建立互信关系，进而提升消费者对CSA的感知价值。基于此，才能提升消费者参与CSA的意愿，并为CSA的本土化发展构建稳固的社会基础。     

The advantage of mobile technologies in crowdsourcing landscape preferences: Testing a mobile app to inform planning decisions

Urban green spaces are vital for cities to achieve sustainability. Optimal design and management of green space is necessary to counter pressure from increased use due to urban densification and therefore needs to account for the preferences of its potential users. However, preference is inherently subjective and difficult to measure. This study tested a crowdsourcing method using a mobile app for on-site data collection to study the use of, perception of, and preferences for different green configurations in the Rembrandtpark, a large urban park in Amsterdam. Responses obtained through the mobile app were compared to those obtained through more traditional on-site and postal surveys to identify differences in sampled population and results. We found clear differences in respondent samples and in stated preferences when comparing the mobile app and the traditional survey methods. Mobile app respondents (n = 154) were younger and more willing to become more involved with park management. They were also less satisfied with most aspects of locations and found them more noisy. On-site survey respondents (n = 146) appeared more susceptible to response bias in their answers to certain questions. Employing different recruitment methods is important to engage different park user types and account for multiple perceptions.     

Analyzing the effects of nature exposure on perceived satisfaction with running routes: An activity path-based measure approach

Studies on the linkages between nature exposure and physical activities often focus simply on the immediate vicinity of home locations, but path-based exercises, such as running and cycling, are continuous activities and cover a broad spatial extent. Thus, the traditional home buffer approach fails to acknowledge the settings where road running actually occurs. This study employed an activity path-based measure approach using public participation GIS (PPGIS) to investigate the associations between running satisfaction and nature exposure. The mapped routes (N=545) that included an assessment of satisfaction level were collected from 249 runners resided in the Helsinki Metropolitan Area, Finland. Logistic regression analyses revealed a positive association between running satisfaction and nature exposure, including eye-level greenness, top-down greenness and blue space density. Top-down greenness was assessed by Normalized Difference Vegetation Index (NDVI) and the eye-level greenness by Green View Index (GVI), the latter one of which uses a deep learning algorithm. Running environment was more satisfying in those routes with more public transport nodes. Other traffic-related factors breaking the momentum of runners such as traffic light density were inversely related to running satisfaction. Demographic characteristics such as education background also played a significant role in the perceived satisfaction with running routes. The positive impacts of nature exposure on running satisfaction further verify the linkages between landscape and public health.     

农户有机肥施用行为与意愿悖离的实证研究

以黑龙江省249户玉米种植户为研究对象，采用Logistic模型和Bootstrap中介效应模型，从农户个体特征、经营特征、认知特征、农地资源特征方面探究农户有机肥施用行为与意愿悖离的影响因素。结果发现，年龄、健康状况、地块分散程度、土壤肥力对悖离的发生有显著促进作用；拥有绿色食品标识、种养兼营、参与施肥培训对悖离发生有显著抑制作用。为减少农户有机肥施用行为与意愿的悖离，提出广泛开展有机肥制备撒施培训、提高有机肥施用机械化程度、积极发展种养结合、加强农产品品牌建设、加快土地经营权有序流转等政策建议。
