基于人工鱼群算法改进栖息地法的河流生态流量计算OACSTPCD

Habitat method,which is widely used in ecological flow calculation,has been questioned for its theoretical basis by many foreign scholars in recent years.Aiming at existing problems,this paper proposes an improved habitat method using the parameters of sight,bonus weight and crowded parameter in the artificial fish swarm algorithm to represent the ability of searching for suitable habitat,the tendency of optimizing habitat after swarming and the logic of selecting habitat.Taking Lutaizi-Huainan section of the middle reaches of Huaihe River as the research area,it is found that the improved calculation method has great stability,can reflect the self-optimizing process of fish habitat selection and embody the utilization of habitat,which can significantly improve the reliability of the habitat method results.
