In order to improve the comprehensive management level of water resources in the Tarim river basin, a regional water ecological security early warning indicator system were established. Combining the Analytic Hierarchy Process (AHP) and the Fuzzy Comprehensive Evaluation (FCE), the complex adaptive mechanism of the water security system was integrated. The watershed overall water security belongs to safer status. Regional water security status showed a certain difference, and overall decreased gradually from west to east. Secondary indicators also different in time and space scale, and showed the geographical consistency. While Aksu and Bazhou were in a slight warning status, and regional water resources development level was moderate. Therefore, the regional economic development and water use efficiency should be enhanced to ensure water safety of the basin.
