Abstract
Vegetation in China experienced serious threat from several driving forces such as population growth and anthropogenic activities. Real-time mapping and assessment of yearly vegetation cover is vital to understand environmental conditions. Here, we examined the trend of vegetation cover changes in China over a 15-year period using remote sensed data. To achieve this, we reclassified the Normalized Difference Vegetation Index (NDVI) values into four classes: No, Low, Medium, and High covers and proceeded to vegetation change detection. The results indicated a difference in values at each level. At the national level, there is an increase in vegetation cover as reflected by High cover class with 41.03% in 2015. At the regional level, the most significant changes were determined in the south where the rate of green cover was declining by -63622.3 km(2) from 2000 to 2015 in the High cover class. Vegetation cover changes varied from province to province. Some provinces showed a reduction in vegetation cover such as Guangdong; whereas Xinjiang experienced an increase (Tables A1 and A2). The findings of this study provide further information on China?s vegetation cover and will also serve as reference for future research.
