Inter-basin water diversion projects are important measure to solve the problem of uneven temporal and spatial distribution of water resources and alleviate the contradiction between supply and demand of water resources.The Yellow River East Diversion Project,Yellow River to Qingdao Diversion Project and Jiaodong Water Diversion Project in Shandong Province are important inter-basin water diversion projects to alleviate the shortage of water resources in Weifang,Qingdao,Yantai and Weihai in Jiaodong area.In order to give full play to the social and economic benefits of the water diversion projects,based on the water shortage in the intake area,the water conveyance capacity of projects,and the designed discharges of the water diversion outlets,the optimal allocation model of water resources for the inter-basin water diversion projects in Jiaodong area is constructed with the minimum comprehensive water shortage rate and the maximum economic benefit of the water diversion projects.The Harris Hawks Optimization(HHO)is used to obtain the water diversion schemes of 16 water diversion outlets under three different targets(with the minimum comprehensive water shortage rate as the leading factor,the maximum economic benefit of the water diversion projects as the leading factor and the two-objective equilibrium)at 50%,75%and 95%frequencies in the current level year and the planning level years.The results show that:(1)the water shortages of the four cities are greatly reduced by diverting the Yellow River water and the Yangtze River water through the water diversion projects;(2)when the proportion of economic benefit target is larger,the higher the water price is,the greater the water supply of the water diversion outlet is;(3)in terms of the utilization degree of the three water diversion projects,the Yellow River East Diversion Project is the highest,followed by the Yellow River to Qingdao Diversion Project and Jiaodong Water Diversion Project.This paper provides decision support for the water resources allocation of the inter-basin water diversion project in Jiaodong area.
