Abstract: The aim of the study was to evaluate water resource carrying capacity in Zhengzhou City, analyze problems in development and utilization of water resource and provide advice for sustainable utilization of water resource. Water availability and demand of water resource were chosen as indexes to build evaluation model and define hierarchical system. By calculating and predicting water availability and demand in the current year (2011) and target years (2020, 2030), water resource carrying capacity of each county in Zhengzhou was evaluated. The results showed that water resource in Zhengzhou was overloaded in 2011. The gap between supply and demand reached up to 1.133 billion cubic meters. Contradiction between water supply and demand from 2020 to 2030 would be alleviated with the implementation of water conservation measures. However, water demand exceeded supply in Gongyi, Xinmi and Dengfeng County because of the rapid development of economy and society and the influence of mountain topography, meaning that severe contradiction between water supply and demand would still exist in the near future in these regions.
