Year: 2017
Type: article
Abstract: According to analysis of authoritative data and previous research results, the total amount of PM 2.5 adsorbed by urban green space was measured in Xuzhou, and its health benefit was assessed through Poisson regression model and environmental health evaluation, also health benefit per unit area of different green space types were compared and analysed in this study. The results showed that the total amount of PM 2.5 adsorbed by urban green space was 8693.64 kg annually in Xuzhou, 198.8 cases of harmful diseases can be reduced average daily, including 89.8 cases of sickness, 100.6 cases of outpatient, 6.8 cases of hospitalization and 1.6 cases of early death; the annual health benefit from decreases of PM 2.5 concentration is about 2.31 billion CNY, which is equal to 0.47% of Xuzhou's GDP in 2014; health benefit per unit area of arbor-shrub-herb is the highest, 28.57 CNY and lawn is lowest, 0.14CNY. Therefore, to appropriately reduce the lawn area, change part of lawn into composite structures of green space such as shrub-herb and arbor-herb is helpful to enhance the efficiency of PM 2.5 absorbed by urban green space, make the quality of urban air better, and further to improve health benefit of urban green space.
