基于改进萤火虫算法和投影寻踪模型的区域水资源承载力评价

Evaluation of the Regional Water Resources Carrying Capacity Based on Modified Firefly Algorithm and Projection Pursuit Model

正确评价区域水资源承载力,对合理开发利用水资源以及促进区域社会经济的可持续发展具有重要意义。以新疆和田地区为例,构建了基于改进萤火虫算法(MFA)-投影寻踪模型的区域水资源承载力评价模型。并将计算结果与PSO算法及GA算法进行比较。结果表明:研究区2012年水资源承载力等级为Ⅱ级,这与其他2种算法的计算结果完全相同,实现了方法对方法的检验。MFA算法在非线性优化问题处理上适用性更强。研究结果为类似地区的水资源承载力评价提供了方法上的借鉴。

The correct evaluation of regional water resources carrying capacity is of great significance for the reasonable utilization of water resources and also the sustainable development of regional society and economics. An evaluation model of the regional water resources carrying capacity is developed for Hotan Prefecture in Xinjiang Uygur Autonomous Region based on the modified firefly algorithm（ MFA） and the projection pursuit model. It shows that the water resources carrying capacity for the studied area is of level II in 2012,which is consistent with the results of PSO and GA algorithms. It also shows that the MFA algorithm is of fast convergence speed and applicability to nonlinear optimization problems. The results provide a useful reference for the evaluation of water resources carrying capacity in similar areas.
