【摘要】：为科学、客观地评价区域水资源利用效率,提出足球联赛竞争(SLC)-投影寻踪(PP)水资源利用效率评价模型,以文山州2006—2015年水资源利用效率评价为例进行实例分析。通过6个典型高维测试函数对SLC算法进行验证,并将仿真结果与教学优化(TLBO)算法、灰狼优化(GWO)算法、差分进化(DE)算法、混合蛙跳算法(SFLA)、粒子群优化(PSO)算法和帝国竞争算法(ICA)的寻优结果进行比较。从综合、工业、农业、生活和生态环境用水5个方面选取23个指标构建水资源利用效率评价指标体系,应用SLC-PP模型,并基于投影系列均值z及标准差σ构造低水平、较低水平、中等水平、较高水平和高水平5个等级的水资源利用效率评价标准对实例进行评价,并分析近10年的水资源利用效率变化趋势。结果表明:(a)无论是单峰还是多峰函数,SLC算法寻优精度优于TLBO和GWO算法,远优于DE、SFLA、PSO和ICA算法,具有寻优精度高、收敛速度快、极值寻优能力强以及收敛稳定性与可靠性好等特点。(b)SLC-PP模型对实例水资源利用效率评价结果均为:2006—2007年处于低水平,2008—2012年处于中等水平,2013—2015年处于较高水平,水资源利用效率随时间呈提升趋势,且提升趋势显著。
[Abstract]:In order to evaluate the utilization efficiency of regional water resources scientifically and objectively, an evaluation model of water resources utilization efficiency is put forward. Taking the water resources utilization efficiency evaluation of Wenshan Prefecture from 2006 to 2015 as an example, the SLC algorithm is verified by six typical high-dimensional test functions, and the simulation results are compared with the teaching optimization algorithm, the gray wolf optimization algorithm and the differential evolution algorithm. The results of hybrid leapfrog algorithm (SFLAA), particle swarm optimization (PSO) algorithm and imperial competition algorithm (ICA) are compared. The evaluation index system of water resources utilization efficiency was constructed by 23 indexes in 5 aspects of water use for living and ecological environment. The SLC-PP model was applied to construct low, low and medium level based on projection series mean z and standard deviation 蟽. The evaluation criteria of water resources utilization efficiency of higher level and higher level five grades are used to evaluate the examples. The results show that the accuracy of the algorithm is better than that of TLBO and GWO, and is much better than that of DESFLAPSO and ICA. The characteristics of extreme value optimization ability and good convergence stability and reliability. The evaluation results of water resource utilization efficiency of the SLC-PP model are as follows: 1. The water resources utilization efficiency is at a low level in 2006-2007 and at a medium level in 2008-2012 and at a higher level in 2013-2015. The utilization efficiency of water resources showed an increasing trend with time, and the increasing trend was significant.
