基于MIKE-BASIN的阳江市水资源配置分析

Water Resources Allocation for Yangjiang City Based on MIKE BASIN

阳江市水资源较为丰富,但时空分配不均,沿海地区径流利用率低,同时存在水源污染和咸潮上溯问题,水资源供需矛盾日益突出。采用MIKE-BASIN水资源配置模型研究表明:阳江市市区取水口上移,由境内大型水库大河水库引水至市区部分区域、阳春市市区及周边,从漠阳江的中下游调水至阳西县,可以在水量和水质方面提高阳江市供水保障水平。

Yangjiang City owns abundant water resources,but the temporal and spatial distribution is uneven.The imbalance of water resources supply and demand of coastal areas is becoming increasingly acute owing to water using difficulty,pollution and saline intrusion.Based on MIKE BASIN water resources allocation model,the study finds that: moving the intake of central city upstream,the water diversion from Dahe Reservoir to central city and Yangchun city,and the water diversion from Moyang River to Yangxi County,can raise Yangjiang City water supply guarantee rate in the aspect of quantity and quality.
