摘要：
An ecological irrigation district is a compound ecosystem integrating production, life, and ecology. Based on the connotation of water resources carrying capacity (WRCC) in ecological irrigation districts, this paper comprehensively considers various factors affecting WRCC in ecological irrigation districts, establishes an evaluation index system of WRCC in ecological irrigation districts, and uses fuzzy set pair analysis theory to evaluate the WRCC in Dagong Yellow River Diversion Irrigation District from 2013 to 2017. The evaluation results show that the WRCC in the Dagong Yellow River Diversion Irrigation District was relatively weak from 2013 to 2014. In 2015, the Irrigation District gradually got rid of the water resources overload until 2017 when the WRCC of a large area in the irrigation district reached the carrying capacity. The evaluation results can provide a scientific basis for optimal allocation of water resources in the Dagong Yellow River Diversion Irrigation District.
