The Contribution of Neighborhood Tree and Greenspace to Asthma Emergency Room Visits: An Application of Advanced Spatial Data in Los Angeles County

摘要: This paper aims to investigate the role of neighborhood tree and greenspace on asthma morbidity, especially emergency room visits. We employed advanced spatial data which allow for precisely capturing both quantity features within a environment. The results from regression models in Los Angeles County revealed that trees greenspace, such as configuration canopy, level clustering, private greenspaces contribute decreasing addition acreages. Notably, however, large scale golf courses, school playgrounds, parks fails reduce number visits at statistically significant level. These findings imply creation dense or clustered patches small-scale might play substantial mitigating air quality consequently reducing
