Index and Energy Quantification Method for Evaluating the Effect of Regional Agricultural Water Resource Allocation

Abstract

【Objective】 The evaluation index of regional agricultural water resource allocation is constructed and the unified quantitative method of the index is developed to provide a decision support for optimal allocation of agricultural water resources. 【Method】 From the overall perspective of regional eco-economic system of agricultural water resources, the index system for evaluating the effect of regional agricultural water resource allocation was established by considering the system structure stability, function effectiveness and environmental carrying capacity. According to the characteristics of different forms and dimensions of the effect in different aspects, a unified measurement method for each index was proposed based on the energy method. Taking Zhengzhou agricultural water resource allocation as an example, we tested the applicability of the proposed method. 【Result】 The important measures of the structural stability are to strengthen water-saving measures on the water demand side and height treatment measures on the sewage treatment side. The important measures on the functional effectiveness are the high treatment measures in sewage treatment and the increasing investment measures in pollutant reduction funds. The important measures on environmental carrying capacity are water supply control measures on the water supply side, enhancing water saving measures on the water demand side and increasing investment measures on the pollutant reduction fund side.
