摘要
由于地形地貌特点,岩溶地区极易发生干旱,为了研究岩溶地区在干旱条件下水资源调配问题,提出了基于遗传算法的多目标水资源优化配置模型,并以广西南丹县为应用实例,分析2020年在干旱条件下南丹县水资源优化配置方案,提出干旱缺水应对措施。分析结果表明,2020年南丹县在正常需水方案下的缺水量较大,而在压缩需水方案下基本能够满足各乡镇社会经济用水需求,建议在干旱年份采用压缩需水方案进行供水配置,为防汛抗旱部门提供理论技术支撑。
Droughts frequently occur in karst areas because of the topographic features. In order to study the allocation of water resources under drought conditions in karst areas,a multi-objective optimization model of water resources allocation based on a genetic algorithm is proposed. Taking Nandan County in Guangxi Province as an example,a water resources optimal allocation scheme in Nandan County under drought conditions in 2020 was analyzed. Based on the results,countermeasures for water shortage were put forward. The results show that in 2020,under the normal water demand program,the water shortage in Nandan County is relatively large,but under the compressed water demand scheme,the demand for social and economical in the area of townships can be basically met. It is suggested to use the compressed water demand scheme in drought years,which provide theoretical and technical support for flood control and drought relief department.
