滨海地区生态型水资源优化配置模型

本文以山东省莱州市为例，在不同水平年工程规划的基础上，结合滨海平原地区海水入侵问 题，分析水资源优化配置的优、劣势影响因素。以平原区地下水采补平衡方程和要求一定的相对入海出境水量为生态需水约束条件，建立水资源优化配置模型。采用水文长系列模拟，分析了2002、2010、2020和2030年4个不同水平年不同措施组合下，不同水资源分区的月供需平衡状况；在保证一定的相对入海水量、未来需水和规划工程条件下，提出了2020年后区域内最大水资源开发能力。

Model for ecological oriented water resources optimal deployment in coastal area

The factors influencing the optimal deployment of water Resources in coastal area are analyzed including the impact of sea-water intrusion. A model for optimal deployment of water resources is established based on the balance of groundwater extraction and recharge, and the condition of a specific relative amount of water that must flow into the sea for the demand of ecological is set as the restriction condition. The case study of Laizhou City, Shangdong Province, is carried out. A long series of monthly balance of water demand and supply for different district in this area for four planning years is simulated. The maximum water resources bearing capacity after 2020 is forecasted according to the principles of ensuring specific amount of sea-going water and enough water for the future demand.
