内容 研究概要:This paper attempts to investigate the relationship between satellite phenology of NOAA/AVHRR-derived Normalized Difference Vegetation Index (NDVI) and rainfall based on vegetation types with study case in East Asia for a specified time period of January 1986 to December 1993, The study examines the relationships of these variables on annual and time series monthly data using both linear and non-linear regression and correlation analysis. The NDVI and rainfall associations are analyzed for twelve vegetations types: deciduous broadleaf forest, evergreen coniferous forest, evergreen broadleaf forest, mixed forest, forest and field, farmland, irrigated crop, grassland, savanna, shrub, semi desert and desert. Based on the relationship between annual integrated NDVI and mean annual rainfall, it seemed there is a marked similarity in regional or spatial structure between the both variables for whole region, but a number of important differences are apparent in the time series analyses. The range of integrated NDVI value, mean annual rainfall, timing of the NDVI response to rainfall, regression slope, and rain-green ratio are clearly demonstrated the differences among the vegetation types.
