Abstract:: Planning of land utilization and land ecological security are the foundations and cores of the sustainable use of land resources. We estimated ecological risk index based on the varieties of land use in the overall planning of land utilization of Yining City at two time points: the base year and the end year through change of land use and the method of ecological risk spatial analysis. After sampling was carried out, the semi-varogram analysis and block Kriging were used to analyze the dynamic evolution and spatial distribution of ecological risk of the land use in Yining City by ArcGIS 9.3. 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 Yining City, ecological security was becoming more severe gradually from north to south, moreover, the high and the higher risk of the southern area had the tendency of ring type spreading. The change of land use in the future, ecological awareness of environmental protection should be strengthened to build an ecological land pattern in Yining valley and improve the comprehensive benefit of land use in the city.
