边际成本分析在水资源开发利用决策中的应用

边际成本分析能对具有技术可行性的水资源开发利用方案作出经济合理性分析。对区域水资源开发利用中有关节水、治污及挖潜等措施的内涵作了界定,并对其边际成本函数特征进行了分析;依据边际成本均衡原理和多目标水资源系统规划理论,提出了区域水资源开发利用中用于节水、治污及挖潜等措施决策方案优选的边际成本分析比较法以及目标规划模型法。以实例计算验证了所提决策方法的可行性。

Application of marginal cost analysis to water resources development

The measures of water resources development with technical feasibility can be economically and rationally analyzed by using the marginal cost analysis method. Therefore, the connotations of several measures in regional water resources development, such as saving water, treating waste water and potentializing other water sources are defined, and the characters of marginal cost curve of these measures are analyzed. According to the principle of marginal cost equilibrium and the theory of mutli-objective decision of water resources system, a method of comparative decision of marginal cost and a goal programming model are proposed to choose the optimal combination of various measures for regional water resources development. The computed example shows the feasibility and effectiveness of the proposed procedures.
