摘要
Vegetation change is of significant concern because it plays a crucial role in the global carbon cycle and climate.Many studies have examined recent changes in vegetation growth and the associated drivers.These drivers include both natural and human activities,but few studies have identified the regulation factors.By employing normalized difference vegetation index(NDVI)data,we analyzed the spatiotemporal pattern of vegetation change in China and then explored the driving factors.It was found that the overall greening of China has improved significantly,especially in the Loess Plateau and southwest China.The Yangtze River Delta and Bohai Rim,however,have not seen as much growth.Natural conditions are conducive to vegetation growth.Although socioeconomic development will be more beneficial for vegetation restoration,the current level and speed of development have a negative effect on vegetation.The regulation factors are considered separately since they affect both directly and indirectly.Regulation factors have accelerated vegetation growth.By understanding the factors affecting the current vegetation growth,we can provide a guide for future vegetation recovery in China and other similar countries.
