Dynamic Assessment of Water Environmental Carrying Capacity of Wenshan Rrefecture Based on Water Cycle Algorithm-Projection Pursuit Model
摘要
Abstract
Using four test functions on the water cycle algorithm (WCA) conducted simulation,the simulation results and Cultural algorithm (CA),Cuckoo search (CS) algorithm and particle swarm optimization (PSO) algorithm simulation results are compared.From the water resources,water pollution,socioeconomic three systems selecting 12 indicators to build regional water environment carrying capacity evaluation index system,using PP WCA optimization model best projection direction.A WCA-PP water Environment carrying capacity assessment model is proposed.And then to build CA-PP,CS-PP and PSO-PP models for camparison,the dynamic evaluation of water environment carrying capacity in Wenshan Prefecture from 2006 to 2015 is taken for example.The results show that:either unimodal or multimodal function,WCA optimizing accuracy and convergence stability are better than CA,CS and PSO algorithms;it has better convergence speed,precision and extreme solving optimization ability.WCA optimization model fitness PP value obtained is 1248.2026;it is better than CA,CS and PSO algorithms.WCA-PP model for instance 2006 to 2011 water carrying capacity evaluation environment is "basic carrying",2012 to 2015 is evaluated "may carry";water environment carrying capacity with time,is to enhance and upgrad obviously.The results of the WCA-PP model are the same as those of the CS-PP model;compared with CA-PP mode,l it is different in every year;and there are differences in the evaluation and ranking compared to the PSO-PP model.The case studies demonstrate that the optimized performance evaluation of intelligent algorithm determines the level of accuracy.The model and validation method have practical value for regional water environment carrying capacity calculation and analysis so as to provide new ideas and methods.关键词
