An Analysis of Vegetation Change Trends and Their Causes in Inner Mongolia, China from 1982 to 2006

Figure 3

The correlation coefficients between the integrated NDVI in the growing season and the accumulated precipitation over the same period. The significance of correlation model was at the 0.05 level. Where NDVI showed significant increase trend, the correlation coefficients were not significant (Banner or county ids: 24, 29, 30, 32, 34, 35, 36, 39, 42,47,50, 53, 55, 56, 61, 64, 69, 70, 71, 72, 73, 74, 75, 76, 79, 81, 82, 83, 85, 87, 88), while where NDVI showed no significant change trends, the correlation coefficients were significant (Banner or county ids: 6, 8, 9, 10, 11, 12, 16, 21, 23, 26, 27, 37, 38, 41, 48, 43, 45, 53, 55, 56, 65, 63, 62, 58, 48).
