Abstract

AVHRR-derived normalized vegetation index (NDVI) is used to examine the paddy field and forest in the northern part of Japan. Twelve sites of the paddy fields and eleven sites of the forest are selected and time series of the NDVI are produced for each of the sites. Two types of NDVI variation pattern are recognized for the paddy field and the forest, respectively. It is suggested that the difference of the variation pattern for the paddy is related to the constitution ratio of paddy and the others, and that of forest to snow amount in winter
