Abstract: Located in arid area, Ningxia Autonomous Region is the important ecological barrier in northwest China and its eco-environment is fragile. The Economic Zone along the Yellow River mainly consists of Yinchuan plain and Weining plain. It is the area with concentrated varies production factors and economic activities. Consisting of geo- environmental subsystem, eco-environmental subsystem and social environmental subsystem, the evaluation index sys- tem was set up based on GIS. The evaluation model of complex system was used to assess the geo-environmental car- rying capacity and the Economic Zone was classified as suitable con
