Data of Urban development patterns and Vegetation trends of Tokyo Metropolitan Area

This data is for the categories of 9 Urban development patterns over 25-year and 5 Vegetation trends over 37-year in the Tokyo Metropolitan Area. To understand how and why the green spaces change in metropolises under accelerating global urbanization, we propose the Normalized Difference Index (NDI) to intuitively quantify and compare the degree of change over a long-time series in built-up areas, population density, and vegetation cover.本数据集涵盖东京都市圈25年跨度的9类城市发展模式与37年跨度的5类植被变化趋势。为探究加速推进的全球城市化背景下大都市绿地空间的变化规律与驱动机制，本研究提出归一化差异指数（Normalized Difference Index，NDI），以直观量化并对比建成区、人口密度与植被覆盖在长时序中的变化幅度。
