Urban green and blue spaces provide mental and physical health benefits for their surrounding communities, but the key to many of these benefits is the utilization of the urban greenspace for recreation or relaxation. For some communities, use is limited by physical access to the greenspace while for other communities, the characteristics of the greenspace play an important role in encouraging or discouraging use. What drives communities to use their local greenspace with respect to all other available greenspace in an urban area remains an underexplored question. To fill this gap, we leverage a large human mobility dataset to track a year of park visitation by residents across the Phoenix, AZ, metropolitan area combined with a spatial autoregressive model using spatially lagged dependent variables. Our results suggest that it is not vegetation but the presence of water features within a park that encourages higher visitation to local parks. Water features also influence visitation to parks outside a communities local area; its presence within a local park decreased how often individuals visited non-local parks as a proportion of their total park visitation. We discuss the implications of these finding in the context of a desert city that lacks both greenspace and water.

是草更绿还是水更蓝？亚利桑那州凤凰城当地公园参观模式的驱动因素

城市绿色和蓝色空间为周围社区提供身心健康益处，但其中许多益处的关键是利用城市绿地进行娱乐或放松。对于一些社区来说，使用受到绿地物理通道的限制，而对于其他社区来说，绿地的特征在鼓励或阻止使用方面发挥着重要作用。相对于城市地区所有其他可用的绿地，是什么促使社区使用当地的绿地仍然是一个尚未得到充分探索的问题。为了填补这一空白，我们利用大型人员流动数据集来跟踪亚利桑那州凤凰城大都市区居民一年的公园参观情况，并结合使用空间滞后因变量的空间自回归模型。我们的结果表明，鼓励更多游客前往当地公园的不是植被，而是公园内水景的存在。水景也会影响到社区以外的公园的参观；它在当地公园内的存在降低了个人访问非当地公园的频率占其公园总访问量的比例。我们在缺乏绿地和水的沙漠城市的背景下讨论这些发现的含义。
