基于广义ET的水资源与水环境综合规划研究Ⅲ：应用

将基于广义ET的区域水资源与水环境综合规划理论与方法应用于天津市,按照"制定目标ET-方案设置-情景模拟-方案评价-方案推荐"的规划方法,提出天津市基于广义ET的水资源和水环境综合规划方案.依据构建的区域水资源与水环境综合模拟模型、量化准则及方案优选方法,以天津市为例进行了应用.针对2020水平年南水北调东线不通水的情况,提出针对天津市水资源与水环境规划的七大总量控制:ET消耗控制量为74.7亿m~3、地表水取水控制量为32.3亿m~3、地下水取水控制量为1.2亿m~3、国民经济用水控制量为28.8亿m~3、生态修复用水控制量为3.2亿m~3、污染物排放氨氮控制量为1.02亿t、COD控制量为7.5亿t、人海水控制量为16.4亿m~3.分析结果表明,基于广义ET的区域水资源与水环境综合规划理论与方法有利于合理解决天津市水资源紧缺、地下水超采、环境污染等问题,支撑天津市社会经济和生态环境的可持续发展.

Comprehensive water resources and environment planning based on generalized evaporation-transpiration water consumption control Ⅲ : Application

The study focused on the application of the theory and methods of integrated water resources and environment planning based on ET control to the Tianjin city. Seven water amount control schemes with the Middle Route of South-to-North Water Transfer Project taken into account were recommended as follows:7.47 billon m~3 of total ET control, 3.23 billon m~3 of surface water consumption control, 0.12 billon m~3 of groundwater consumption control, 0.32 billon m~3 of ecology consumption control ,2.88 billon m~3 of living-industry-agriculture consumptive control, 0. 102 billon t of ammonia N discharge, 0.75 billon t of COD discharge and 1.64 billon m~3 of outflow to sea. The results revealed that the theory and methods of integrated water resources and environment planning will play a important role in solving water resources scarcity, ground exploration, water environment pollution, and greatly promote the sustainable development in society, economy, ecology and environment.
