Abstract: Vegetation coverage is an important factor describing the restoration and growth of vegetation in a region. Accurately and efficiently quantifying the effects of vegetation coverage is changeing and spatiotemporal characteristics before and after FAST project implementation. Moreover, landscape indexes were also introduced to quantitatively understand vegetation coverage over the past 10 years. Based on the Landsat TM/OLI remote sensing images, the vegetation coverage of FAST radio quiet zone from 2008 to 2018 was retrieved, the Fragstats 4.2 was used to analyze the landscape pattern simultaneously. In this paper,（1) the overall vegetation coverage of FAST radio quiet zone from 2008 to 2018 was good, and the growth trend of woodland was so obvious that vegetation coverage in this zone shows spatiotemporal differences. For vegetation types, the region was dominated by low-medium and medium coverage vegetation in 2008, and most of them were medium-high and high coverage vegetation in 2018.(2) It can be seen from transition martrix of vegetation coverage that the area increased by vegetation coverage was much larger than degradation, and the growth trend was significant. The FAST core area of vegetation coverage was 48.01 km²  from 2010 to 2016, and degraded was only 16.19 km ². The actual performance was that ecological environment quality of FAST core area was obviously improved, and woodland areas were increased.（3) There were similarities and differences in spatiotemporal patterns among different types of vegetation in FAST radio quiet zone. The increase of woodland areas had a positive effect on vegetation coverage. With the patch density and the number of patches declines, landscape fragmentation was reduced, connectivity was enhanced, the landscape pattern tended to be stable, and the degree of aggregation increasing. It shows that effective woodland protection measures have a great impact on the landscape pattern of this area, and stable landscape pattern plays an important role in the protection of FAST site. In conclusion, our study shows that remote sensing monitoring support for the vegetation protection in different areas of this area.
