| Research Abstract |
The relationships between human activities and the global change in vegetation was investigated by using Monthly GVI(Global Vegetation Index)data sets from 1983 to 1988 and thematic map data sets related to human activities.
The results obtained from this study are as follows :
(1)The GVI data analysis system was constructed.
This system was mainly made by the Image-Map database system which includes GVI data, thematic map data and statistical data such as populations in countries.
(2)The correlation analysis between Yearly GVI value and population in a country was performed.
This analysis is based on the assumption that the population in the country is an important factor for the assessment of human activities. As a result, the world map of coutries with high correlation between the time variation of the population and the temporal change in vegetation was produced.
(3)The relationships between human activities and biosphere obtained.
The supportability of population with respect to the crop production was estimated by using the NOAA GVI data and potential arable land areas provide by FAO.
