Abstract Using four sets of remote sensing images in 1976, 1988, 2001 and 2011, and with ecological quantity analytical method, we analyzed the change of land use patterns and landscape pattern in about 40 years in the Murghab-Tejen Oasis in Turkmenistan. The results were as follows: (1) There happened a significant land use/cover change in the studied area. The areas of woodland, arable land, desert and saline soil showed increased, while that of grassland, water region and other area decreased. The fastest change rates of land use occurred in grassland (in 1976-1988), water region (in 1988-2001), grassland (in 2001-2011), and arable land (in 1976-2011), respectively. (2) The Total Area(CA), Percentage of Landscape(PLAND), Number of Patch(NP), Edge Density(ED), Landscape Division Index (LPI), Interspersion and Juxtaposition Index(IJI), Splitting Index(SPLIT) and Patch Cohesion Index (COHESION) at class level, and the Shape Area-Weighted Mean(SHAPE_AM), Patch Density(PD), Landscape Division Index (LPI), (ENN_MN), Contagion Index (CONTAG), Shannon's Diversity Index (SHDI), Simpson's Diversity Index (SIDI), Interspersion and Juxtaposition Index(IJI), Splitting Index(SPLIT) and Patch Cohesion Index (COHESION) at landscape level all showed that the number of the patches increased and landscape fragmentation presented an increasing degree. The connectivity of patches reduced. It would be essential to optimize the land-use pattern and to maintain the continuity of landscape ecological process and pattern in the Murghab-Tejen Oasis if sustainable development of land resources and ecological environment protection were expected.
