Casual evaluation of the effects of a large-scale greenway intervention on physical and mental health: A natural experimental study in China

Many cross-sectional studies have supported the health benefits of urban greenways. However, the causal relationship between urban greenway intervention and residents’ physical and mental health remains unclear. Furthermore, the potential dose-response effect by distance to a greenway intervention remains unknown. This study explored the impact of a large-scale urban greenway intervention (construction of a 102-km-long East Lake Greenway in Wuhan, China) on the health outcomes of residents by using a natural experimental research design. We collected data before and after the intervention (in 2016 and 2019, respectively) from 1,020 participants living within a 5-km street-network distance from the entrances of this greenway. The average age of the participants was approximately 50, and most of them were married. More than half of the participants were female, currently employed, and had received a college education or above. Mixed-effects difference-in-difference (DID) models were used while controlling for individual and neighbourhood covariates. The results showed that the East Lake Greenway had a positive effect on the self-reported mental health of residents who lived within 2 km, and these benefits decreased with distance. The physical health benefit was insignificant. To increase the health benefits of urban greenways, more effort should be made to improve the accessibility of greenways and the surrounding environment. We also advocate that future natural experiments should explore the distance-varying dose-response effect of green space interventions on health outcomes.     

Greenway service supply and public demand in Guangzhou city,China

Small-size green spaces contain convenient service capabilities for urban residents and satisfy the daily needs of citizens for high-quality ecological products. A greenway is a kind of linear green space, which can create a beautiful and livable environment in a high-density urban area. This study explored whether the services provided by the greenway can meet the daily needs of urban residents for green space in Guangzhou, a mega city in south China. Based on the Analytic Hierarchy Process (AHP) method and the entropy weight (EW) method, both the coupling coordination degree model and spatial autocorrelation analysis were adopted to quantify and determine the coordination degree of greenway service supply and public demand in Guangzhou. The results showed that the comprehensive score of the greenway service supply (GSS) subsystem and the public demand (PD) subsystem in Guangzhou was 0.3865 ± 0.08 and 0.3778 ± 0.03 (mean±s.e., n = 11), respectively. The GSS subsystem score was slightly higher than that of PD subsystem (P > 0.05), indicating that the two subsystems had no significant differences. The supply and demand subsystem of ten districts (excluding Conghua) in Guangzhou achieved different levels of coordination, and the average coupling coordination degree was 0.5885, suggesting that the districts were barely balanced at the city level. The Moran's I value was 0.580, indicating that the coupling coordination degree had significant positive global spatial autocorrelation and showed a spatial agglomeration effect. Furthermore, the local Moran’s I spatial autocorrelation showed that three districts (i.e., Yuexiu, Haizhu and Liwan) formed a high supply-high demand cluster and a spatial difference was detected when coupling the GSS and PD in Guangzhou. Therefore, we proposed the differentiated optimization strategies based on the results of the coupling coordination degree and the development status of each district and the entire city. This knowledge can better guide the subsequent construction and development of greenway in Guangzhou and may be useful for adjacent cities in Asia-Pacific region.     

Incorporating landscape diversity into greenway alignment planning

As an important factor of scenic quality and biodiversity along a greenway, landscape diversity has yet to receive as much attention as it deserves. In the practice of greenway alignment planning, it usually gives way to the primary consideration of land suitability. In this article, we aim to make up this missing link. Upon the new concepts and measurement of linear landscape diversity and cellular landscape diversity, we proposed greenway potential index incorporating land suitability and landscape diversity. The greenway potential index was combined with connectivity analysis to connect path between a future greenway’s origin and destination that meets both land suitability and landscape diversity requirements. Specially, with Wuchang (Wuhan City, China) as a case study area, we proposed three greenway alignment planning scenarios respectively according to the criteria of suitability, diversity and the synthesis of them. Markedly differences were revealed between the results of suitability greenways and diversity greenways. The results indicate that the tripartite model we proposed is capable of planning a connecting path between a future greenway’s origin and destination that not only meets land suitability requirements for greenway construction, but also incorporates as many landscape types of significant difference as possible.

“森林城市”模式与城市绿地园林景观及功能的弱化

“森林城市”的提法导致城市园林绿化建设模式产生一定的偏差，“森林城市”忽视了城市内绿地与城市外绿地功能的诸多差异，甚至导致城市园林绿地丧失其应该体现的园林艺术特征和休闲、游憩、娱乐、健身等综合功能。除生态效益之外，只有强调城市绿地的园林艺术特征和多功能性才能防止城市绿化中过密、过滥的“森林式”的种植模式。正确定位城市中心和城市外围两种不同地域绿地的功能和结构，并以生态的楔形绿地为桥梁是实现城内外绿地相互联系、功能互补的一个有效途径。     

The effects of urban greenway environment on recreational activities in tropical high-density Singapore: A computer vision approach

The urban greenway has been increasingly recognised as an important type of green infrastructure especially for land-scarce, densely-populated cities to efficiently provide their residents with continuous public spaces close to nature for recreation. Nevertheless, empirical studies on urban greenways and their recreational use rarely focus on high-density environment. Moreover, most research endeavours in this field are also largely confined to the subtropical climate, whereas much of the world’s future urban growth is projected to occur in the form of high-density mega-cities in much of tropical South and Southeast Asia. In view of these gaps, this study proposes a new approach that employs Computer Vision tools to examine the effects of the greenway’s physical environment on recreational activities, taking tropical Singapore as the test bed. The semantic segmentation model, PSPNet and the action detection model, ACAM are adapted and applied in conjunction with geographical information system tools to measure the greenway’s physical environment and people’s recreational activity at the human scale, and analyse their relationships. The result reveals a pattern that sees the clustering of different types of recreational activities at different time periods. It also reveals the relationships between recreational activities and specific environmental features, which were observed to have influenced the overall spatial distributions of the recreational activities. The finding also corroborates the design strategies for Singapore’s future urban greenways and offers a reference for engaging community groups to participate in the maintenance of urban greenways.
