- Abstract:
- Based on the MODIS/Terra NDVI remote sensing data, the vegetation coverage from 2000—2010 in Hedong region was estimated and the spatial and temporal change characteristic of vegetation coverage and the driving factors was analyzed by using the dimidiate pixel model. The results showed that the average vegetation coverage was 50.93% in Hedong region where the vegetation coverage was maximum in Gannan Plateau, and the minimum value distributed in the northwestern part. The vegetation coverage decreases from south to north. The average vegetation coverage more than 60% occupied 23.06% of the region. The regional vegetation coverage in the 90.49% of the region had an increasing trend, especially in the middle of Hedong region where the vegetation coverage increased fastest (33.68%). It can be seen rainfall was the main factor on the spatial scales, and afforestation was the key influence factor on the time scale.
