摘要:Rapid expansion of cities and mega-cities often affects the surrounding environment, reducing environmental sustainability and leading to other negative effects. To achieve a sustainable urban environment, it is critical that green spaces expand in harmony with urban expansion in a rational manner, compensating for losses in the environment due to urban growth. In this study, land use maps including 6 classes of green space, urban areas, roads, river, agriculture lands, and barren land were produced using maximum likelihood algorithm for 2010 and 2016 and the landscape metrics were analyzed using FRAGSTATS software. Then, a partial least square (PLS) model was applied to assess the effects of changes in the pattern of green space on air pollution. The model results indicate that reduction in the area of large green space patches promote air pollution, suggesting that there is a direct relation between increases in the area of large green space patches and air pollution reduction.
