上海城市土地利用/覆盖演变对空气环境的潜在影响

Urban Land Use/Cover Dynamics of Shanghai Metropolitan Area and its Potential Impact on Local Air Environment

以上海市区为主的高强度开发地区为例,运用空间自相关分析和分维/分形分析方法,探讨了城市化土地利用/覆盖对区域空气环境安全水平的潜在影响,认为用地类型转变导致的土地覆盖的变化将降低区域空气环境的潜在安全水平并增加人类健康损失的潜在机率.

Based on the classification of urbanized land cover types of Shanghai Metropolitan area, which was significantly characterized with artificial buildings, infrastructures and disturbed semi-natural landscape, the potential impact of land use/cover changes was studied with autocorrelation analysis and fractal analysis, and the further conclusion was that with the rapid growth of urbanized landscape and drastic change of land cover, potential negative impact on urban air environment and eco-risk of urban population would increase.
