- Abstract:
- There is relatively dense population in terms of oasis in arid areas, and results from human activities directly reflect the oasis dynamics in spatiotemporal change of land-use, which provides a premise for this paper to conduct feasible and scientific methods for analyzing the dynamic change of land-use. In this paper, with the support of 3S technology, MSS, 1992 ETM images in 2000 and 2000, and 2006 TM images in the two total different periods, and the use of supervised classification method, combining with 1∶50 000 land use status image of study area in 2008, and on-the-spot investigation data, the temporal change of land use of Dina river oasis was analyzed. The reslults showed that: (1) from 1992 to 2011, larger changes had taken place especially in land type in the study area: the areas of farmland, construction land were increasing; and forestland, grassland area continued to decline; grassland area, first reduced, then increased and declined at last, the total area presented the declining trend; (2) the analysis of changes in the rate of land-use indicated that the study area had experienced the linear speed of change under the situation of land use change; (3) the index of land utilization in Dina River oasis during 20 years comprehensively rose to 50.49, which reflected that the land use in the study area was at the middle stage of development, it had to do with the natural geographical environment and the economic and social development in the study area.
