THE CORRELATION BETWEEN METEOROLOGICAL FACTORS AND NDVI IN NORTHEASTERN CHINA
Krigging method is used to interpolate precipitation and temperature data from 1982 to 1999. As a result, meteorological factors images with two dimensions in the Northeast China are produced. Then zero and month time lag correlation between meteorological factors and NDVI is analyzed with meteorological factors images and NDVI images of monthly, season and yearly mean. Thereby, the conclusion includes the following aspects: (1) forest vegetation types with highest correlation between meteorological factors and NDVI, (2) forest vegetation types with higher month time lag correlation than zero month time lag correlation, and forest vegetation types with lower month time lag correlation than zero month time lag correlation, (3) Temporal and spatial variability of correlation between forest vegetation types and meteorological factors.
