This study is to evaluate the overall NPP(Net Primary Production) distribution in the Korean Peninsula from the satellite data(NOAA/AVHRR). This has been done using the linear relationship between the natural vegetation condition and the NPP. The NPP of natural vegetation increases proportional to the annual net radiation(Rn), where radiative dryness index(RDI) is a proportional constant connecting Rn to NPP. Normalized Difference Vegetation Index(NDVI) is used for monitoring vegetation change, and iNDVI (integrated NDVI) for annual analysis. The iNDVI has a close relation to Rn and NPP, which can be used effectively for estimating NPP distribution of where the meteorological data is unavailable such as North Korea. The NPP distribution of the Korean Peninsula was estimated based on the model.
