Abstract: Using RS and GIS technology to extract the normalized vegetation index（NDVI）,and using Sentinel-2 A remote sensing data to construct the Nanchang city center green space landscape data set,apply the principles of landscape ecology to quantitatively study the green space landscape pattern of the study area and discuss the correlation between different types and regions of urban vegetation coverage and green landscape patterns.The results showed that the total number of green patches in the study area was huge.Among them,the economic development zone had the highest green rate and the Donghu area was the smallest.The subsidiary green land accounts for the largest proportion of other types of green land greespace;the green land was unevenly distributed and the overall green patch edges were relatively regular.Severe human-made interference;the old urban area,especially the subsidiary greenspace and square land greenspace,had a relatively large fragmentation level and cannot exert its ecological benefits;high vegetation coverage was conducive to the formation of large areas,complex shapes,and relatively concentrated spatial distribution.Block,the higher the vegetation coverage,the lower the fragmentation level.Propose planning suggestions to the analysis results balance the distribution of various types of green space and increase landscape diversity;combine the urban context to transform the old city environment;make full use of the original ecological resources and rationalize development.
