Character of Vegetation Coverage Change along Coastal Areas of Maritime Silk Road

The character and trends of vegetation coverage change along coastal areas of Maritime Silk Road during 2000~2016 has been studied based on MOD13C2 data using MVC method，Change Vector Analysis(CVA)，linear regression，Hurst index and Spatial Analysis techniques，therefore generating the change map of vegetation coverage．The results showed that the vegetation coverage significantly increased from 2000 to 2016，and about one|third of the area changed.The vegetation improvement area accounted for 28.31% of the whole study area and the degradation area was 5.33%，and there was evident self|similarity and long|range dependence of vegetation coverage change.The significant vegetation improvement areas were concentrated in South Asia and Western Asia.In addition to part of the concentrated distribution in Africa，the vegetation degradation area scattered along the coastline.Analysis showed that the vegetation coverage was affected by the intensity of human activities along the coast and overall economic development in the region，such as China and Southeast Asia，whose economy is at a stage of development，although the overall vegetation coverage showed improvement and basically unchanged trend，about half of the ports in the region showed the trend of vegetation degradation.However，the economy of Europe are flourishing，the vegetation coverage around the port is mostly improved.
