针对中山市日益加剧的水资源供需矛盾和咸淡水利用率低的问题,基于一维河网区盐度模型,计算分析了中山市咸淡水资源量及其时空分布特征。结果表明,中山市咸淡水资源量较为丰富,年可利用量约54.20×108 m3,其中磨刀门水道与横门水道分别为16.00×108、21.60×108 m3/a,民众镇、南朗镇与板芙镇的咸淡水可利用量分别为14.70×108、10.80×108、6.11×108 m3/a。但咸淡水资源量时空分布较不均匀,且资源利用率较低,仅为4.4%。因此,建议中山市咸淡水可应用到农业灌溉、水产养殖、电厂冷却用水及生活冲厕用水等。研究成果为中山市咸淡水开发利用模式提供参考。
In view of the increasing contradiction between supply and demand of water resources and the low salt and fresh water utilization rate in Zhongshan City, based on the one-dimensional river network salinity model, the amount of fresh and brackish water resources in Zhongshan City and its spatial and temporal distribution characteristics are calculated and analyzed. The results showed that the amount of fresh and brackish water resources in Zhongshan City was relatively rich, with an annual usable capacity of 54.20 × 108 m3, of which Shamo Shutou and Hengmen were 16.00 × 108 and 21.60 × 108 m3 / a, respectively. Minzhong and Nanlang Towns The availability of brackish water with Banfu Town was 14.70 × 108,10.80 × 108 and 6.11 × 108 m3 / a, respectively. However, the spatial and temporal distribution of fresh and brackish water resources is not uniform, and the resource utilization rate is relatively low, only 4.4%. Therefore, Zhongshan City, fresh and brackish water is recommended for agricultural irrigation, aquaculture, power plant cooling water and domestic flushing water. The research results provide a reference for the development and utilization of brackish water in Zhongshan City.
