摘要

城市河流在提供生态系统服务方面发挥着至关重要的作用,这些服务有助于城市居民的社会福祉和生活质量。然而,快速的城市化导致了这些河流的逐渐退化,影响了它们输送ES的能力,并产生了重大的社会生态影响。本研究对厄瓜多尔洛贾的城市萨莫拉河和马拉卡托斯河及其ES中的非货币社会价值观(积极和消极)进行了参与性测绘,以了解退化景观背景下的社区认知和偏好,作为对传统方法的补充分析类别。在方法上,收集、分析和绘图是使用基于调查的公众参与地理信息系统(PPGIS)进行的。这种方法促进了社会数据与生物物理变量的整合。在所研究的十种社会价值观中,最相关的是积极的:学习、审美、治疗和消极的:缺乏、缺乏和无法获得的基础设施以及洪水的威胁。我们揭示了每个ES社会价值的不同空间模式,其中正值位置表现出分散模式,在外围地区呈集群模式,而负值位置在市中心呈集群模式。贡献最大的环境变量是到绿地的水平距离。这些发现增强了我们对城市河流环境中与ES相关的社会价值观和偏好的理解。此外,它们为确定机会和冲突领域、为社区规划和城市景观的有效管理提供了宝贵的见解。

Evaluation and mapping of the positive and negative social values for the urban river ecosystem
Urban rivers play a crucial role in providing ecosystem services (ES) that contribute to the social well-being and quality of life of urban inhabitants. However, rapid urbanisation has led to the progressive degradation of these rivers, affecting their capacity to deliver ES and resulting in significant socio-ecological impacts. This study performs a participatory mapping of the non-monetary social values (positives and negatives), in the urban Zamora and Malacatos Rivers and their ESs, in Loja, Ecuador, to understand community perceptions and preferences in a context of degraded landscapes as a complementary category of analysis to traditional approaches. Methodologically, the collection, analysis and mapping were carried out using public participation GIS (PPGIS) based on surveys. This method facilitated the integration of social data with biophysical variables. The most relevant of the ten social values studied were positives: Learning, Aesthetic, Therapeutic and negatives: Displeasure, Deficient and Inaccessible Infrastructure and Threat of Flooding. We revealed different spatial patterns for each ES social value, where positive value locations exhibited a dispersed pattern, with clusters in peripheral areas, while negative value locations exhibited a clustered pattern in the city centre. The environmental variable with the most significant contribution was the Horizontal Distance to Green Areas. These findings enhance our understanding of the social values and preferences associated with ES in urban river contexts. Furthermore, they provide valuable insights for identifying areas of opportunity and conflict, informing community planning and effective management of the urban landscape.
