Urban green spaces, a form of green infrastructure, provide cities with a number of opportunities to build urban resilience to withstand a wide range of urban challenges, such as land-use change, climate change, biodiversity loss, and physical and mental health. Despite their benefits to communities, urban green spaces are among the most valuable and attractive areas for development and are most susceptible to urban development. Therefore, careful planning of the green space network is needed,requiring diverse voices from not only city policymakers and planning experts but also local residents. This study investigated residents’ perceptions and preferences for green space development and its association with perceived flood risk. Data were collected from residents residing in two Texas Gulf Coast cities via a Public Participation Geographic Information System (PPGIS) platform. Our analyses revealed that Texas Gulf Coast residents assigned a full spectrum of landscape values to their existing urban green spaces with aesthetic and recreation values being most frequently identified. Notably, across the city landscape, urban green spaces that were most favored by residents tended to be green spaces with water bodies, large in scale and offered a broader array of facilities/amenities. These spaces were also identified as flood-prone areas, presenting opportunities for green space improvement, flood protection, and preservation. In addition, we observed a significant association between residents’ risk perception and the number of locations across the city landscape they perceived as posing the greatest flooding threat. Our findings illustrate a need to promote multiple landscape values of urban green spaces, especially in its ability to protect the city from future flooding. This research highlights how PPGIS can support green infrastructure planning as well as enhance public participation in green infrastructure planning processes.

利用公众参与地理信息系统了解德克萨斯州沿海社区对城市绿地开发的看法和偏好以及对洪水风险的看法

城市绿地是绿色基础设施的一种形式，为城市提供了许多建设城市韧性的机会，以应对各种城市挑战，例如土地利用变化、气候变化、生物多样性丧失以及身心健康。尽管城市绿地对社区有好处，但它是最有价值和最具吸引力的开发领域之一，并且最容易受到城市发展的影响。因此，绿地网络需要精心规划，不仅需要城市政策制定者和规划专家的声音，还需要当地居民的不同声音。本研究调查了居民对绿地开发的看法和偏好及其与感知洪水风险的关系。数据是通过公众参与地理信息系统 (PPGIS) 平台从居住在德克萨斯州墨西哥湾沿岸两个城市的居民收集的。我们的分析显示，德克萨斯州墨西哥湾沿岸居民为其现有的城市绿地分配了全方位的景观价值，其中最常被识别的是审美和娱乐价值。值得注意的是，在整个城市景观中，最受居民青睐的城市绿地往往是拥有水体、规模较大、设施/生活设施更广泛的绿地。这些空间也被确定为洪水易发区，为绿地改善、防洪和保护提供了机会。此外，我们观察到居民的风险感知与他们认为构成最大洪水威胁的城市景观位置数量之间存在显着关联。我们的研究结果表明，需要提升城市绿地的多重景观价值，特别是其保护城市免受未来洪水侵袭的能力。这项研究强调了 PPGIS 如何支持绿色基础设施规划以及增强公众对绿色基础设施规划过程的参与。
