Study on Landscape Pattern Vulnerability of Ecological Environment and Spatial Correlation in Shanxi Province

He Jia;Zhang Ying;School of Environmental and Chemical Engineering,Xi'an Polytechnic University;  
This paper analyze landscape pattern vulnerability of ecological environment and spatial correlation in Shaanxi Province by using Geographic Information System( GIS) and landscape pattern index calculation( Fragstats). The results indicated that,the landscape pattern vulnerability were 0 ~ 7. 406 6,0 ~ 7. 970 5 and 0 ~ 8. 034 8 in Shaanxi Province in 2001,2006 and 2011,respectively,showed a downward trend,high vulnerable area decreases gradually,low vulnerable region and lower vulnerable area gradually increased. The global Moran's I index in 2001,2006 and 2011 was 0. 792 8,0. 692 1 and 0. 679 9,respectively,showed a decreasing trend,and there was a strong positive correlation between the landscape fragility. The local autocorrelation showed that the region of"high-high"in 2001 was mainly distributed in the middle and south of Shaanxi Province. In contrast,the area of "high-high"in 2006 was distributed in regions other than the central and southern. The region of"high-high"in 2011 was distributed in regions other than the Midwest.
