摘要： 针对单目标评价方法无法有效地评价火电工业取用水定额的优劣程度问题,基于投影寻踪法对长江流域火电工业取用水定额进行了多目标评价。首先分析了单目标评价方法对火电工业取用水定额的优劣评价结果;在此基础上开展了基于投影寻踪法的长江流域火电工业取用水定额的多目标评价研究。研究结果表明:长江下游地区的江苏华能太仓电厂三期工程的综合评分最高,而长江下游地区的江苏南通新区热电厂二期扩建工程的综合评分最低,评价结果相对合理客观。基于投影寻踪法的多目标评价相比单目标评价方法,可有效传递和辨识评价指标的信息价值,可给出长江流域火电工业取用水定额合理且客观的综合评价,推荐采用差评、合格、良好和优异4级综合指标划分法对火力发电厂取用水定额进行分级评价。

Abstract: Single-objective evaluation method cannot effectively evaluate the rationality of water intake quantity and quota of fossil-fuel power station. In view of this, a multi-objective evaluation method based on projection pursuit was employed to evaluate the reasonability of water intake quantity and quota of fossil-fuel power stations in Changjiang River basin. Firstly, single-objective evaluation method was applied to evaluation and the result was analyzed. On this basis, multi-objective evaluation was conducted. Results show that the comprehensive score of Taicang fossil-fuel power station phase III is the highest and Nantong thermal power plant phase II is the lowest. This multi-objective evaluation method based on projection pursuit could effectively identify the information value of evaluation indexes, and give rational and objective assessment result. Four ranks (unqualified, qualified, good, and excellent) are recommended for the rating.

Key words: fossil-fuel power station, water intake quantity and quota, Changjiang River Basin, projection pursuit method, single-objective evaluation
