Urbanization has profoundly changed urban landscape patterns, therefore, altered the spatiotemporal patterns of urban atmospheric and thermal environment, such as particulate matters (PMs) and heat wave. Previous studies demonstrated that PMs and extreme temperature events due to urbanization have great adverse impacts on public health. However, whether and how urban landscape pattern changes resulted from urbanization influence urban mortality remains unclear. In this study, we hypothesized that urban landscape heterogeneity will result in spatial variations of urban human mortality. To test this hypothesis, long term time-series datasets of Shanghai since 2000, including non-accidental all-cause human mortality records, air pollution monitoring data, meteorological data, as well as urban land use/land cover data, will be employed to reveal the spatiotemporal patterns of urban human mortality, to relate urban human mortality to PMs, and further to explore whether and how urban landscape pattern dynamics influence urban human mortality at multiple scales utilizing different approaches, such as time series analysis, spatial analysis in GIS, geostatistics, medical statistics and landscape pattern analysis, etc. The results of this program will help better understand the relationship between urban landscape patterns and public health, provide insights for urban landscape optimization, urban planning and design, which aim to improve urban living conditions and public health, and further to enhance the ecological security of urban environment.
