摘要
根据松嫩平原西部水资源复合系统的特征和水资源条件,建立了区域水资源可持续利用评价指标体系。应用投影寻踪技术,采用实码遗传算法优化投影指标函数,将方案多维评价指标值综合为一维投影值,根据投影值的大小实现方案的优选。研究表明,投影寻踪技术可以有效地解决权重的人为干扰,通过优化排序实现对评价结果的定量化表征。
In terms of the characteristics of water resource compound system and the conditions of water resources, an evaluation system of sustainable water resource utilization has been established according to the principles of sustainability. Projection pursuit model （PPM） and real coding based genetic algorithm （RGA） have been used in the evaluation, which can synthesize the multiple factors into a single pursuit value and attain an optimal scheme. The result shows that it is effective to solve the weighted human interference, and fulfill the evaluation of sustainable water resource utilization by an optimized sequence.
