| Scientific and rational evaluation of the stability of land use landscape pattern in the process of urbanization is the basic work to optimize the land use landscape pattern and reduce and prevent the ecological environment risk. Taking Nanchang city as an example, the internal stability of land use landscape in the process of urban expansion from 2006 to 2016 was analyzed by using RS and GIS technology and TM image interpretation results in 2006, 2010 and 2016. The results showed that: (1) Among the land use landscape types, urban construction land and cultivated land were the main landscape types in Nanchang, accounting for 35.24% and 25.94% of the study area in 2016, respectively. Landscape advantages were obvious, and they were also the main part to control the stability of land use landscape pattern. (2) Landscape stability of land use in Nanchang is obviously different on the whole. The main characteristic is that the urban construction land increases continuously, from 250.41 km2 in 2006 to 311.76 km 2 in 2016. The area of woodland, grassland, water area, unused land and cultivated land changes little. The stability of land use landscape pattern showed an upward trend in the study area. |
