Abstract:: To explore the evolution process of urban expansion and landscape fragmentation and its correlation mechanism, taking Nanchang City, Jiangxi Province as an example, based on the land use data from 2000 to 2015, the urban fragmentation index(UFI)was used to describe the landscape fragmentation level of construction land; then combined with morphological spatial pattern analysis(MSPA)and landscape connectivity analysis, the dynamic evolution process of natural landscape and cultivated land was quantified. Finally, grid analysis was used to explore the dynamic characteristics of spatial autocorrelation among the three. The results show that from 2000 to 2015, a total of 273.26 km² of cultivated land and 45.61 km² of natural landscape in Nanchang were converted to construction land, and the overall urban fragmentation index increased from 2.27 to 4.94 during the study period; the number of cultivated land core areas continued to decline in 15 years, and the natural habitat changed steadily in the early stage; with the acceleration of urbanization, the core and bridge areas continued to decrease, and the island patches began to increase; spatial autocorrelation analysis showed that landscape fragmentation was negatively correlated with the average connectivity probability of natural habitat and cultivated land; the high and low aggregation areas between landscape fragmentation and the average connectivity probability of cultivated land and natural habitat concentrated in the main areas of urban expansion. Fragmentation caused by the rapid urban expansion from 2000 to 2015 led to changes in the landscape structure of cultivated land and natural habitats, and the gradual loss of landscape connectivity.
