【 摘 要 】

The evaluation indexes of total water consumption and water use efficiency have the characteristics of post feedback. In this paper we introduce the basic concept and specific theory of Earned value method (EVM) from project management, and reconstruct parameters in the method to adapt to water resources monitoring. The case of Dandong was studied, by analyzing the industry and irrigation water utilization. Although the total water consumption of two aspects reaches standards, the industrial added value and water use efficiency of irrigation are not up to standard. The results show that PV can be used as a baseline for real-time monitoring and adjustment, and the advantage of the EVM is that it can be an organic unity of water consumption and efficiency, so we can analyze comprehensively water utilization process.
