Observed inequality in urban greenspace exposure in China

Given the important role of green environments playing in healthy cities, inequality urban greenspace exposure has aroused growing attentions. However, few comparative studies are available to quantify this phenomenon for cities with different population sizes across a country, especially those developing world. Besides, commonly used measures always hindered by conceptual simplification without accounting human mobility assessments. To fill knowledge gap, we leverage multi-source geospatial big data and modified assessment framework evaluate 303 China. Our findings reveal that majority Chinese facing high exposure, 207 having Gini index larger than 0.6. Driven spatiotemporal variability distribution, magnitude varies over times day. We also find is correlated low provision statistical significance (p-value < 0.05). The inadequate may result from various factors, such as dry cold climate urbanization patterns. study provides evidence insights central local governments China implement more effective sustainable greening programs adjusted circumstances incorporate public participatory engagement achieve real balance between supply demand cities.
