Land ecological security is the core and foundation of the sustainable use of land resources. This paper estimated ecological risk index based on the varieties of land use in the overall planning of land utilization of Awati at two time point-the base year and the end year through change of land use and the method of ecological risk spatial analysis. After samplings were carried out, the semi-varogram analysis and block Kriging were used by ArcGIS 10.0 to analyze the dynamic evolution and spatial distribution of ecological risk of the land use in Awati. The results indicated that the spatial structure of land use had been a major adjustment in the overall planning of land utilization, the spatial distribution of land ecological risk was imbalanced in Awati, ecological security was becoming more severe gradually from south to north and the area with high ecological risk had the tendency to spread from north to northwest and southwest. The change of land use in the future, ecological awareness of environmental protection should be strengthened to build an ecological land pattern in Awati oasis and improve the ecosystem services in the county.
