Abstract: Quality use of water resource is a vital way to deal with water crisis under the concept of sustainable development. Study on water resource allocation can not only provide solutions to water resource supply-demand conflict, but also boost a sustainable use of water resource, and also guarantee a quality social & economic development. This paper, based on a case study on Nanjing city, establishes a water resource optimized allocation model of multiple target areas under three red lines control, which is given solutions by applying multiple particle swarm algorithm in obtaining water resource optimized allocation plans for planning years. Results show Nanjing will have a water supply of 3.441 billion cubic meters in 2030 under three Red Lines control with a water shortage rate up to 8.22%. Industrial, agricultural and living water is the major uses with a fast-growing environmental water use. COD and Ammonia-Nitrogen are under good control, reaching a balanced development among economic, social and environmental benefit objectives. This paper presents suggestions on coordinating water supply-demand, optimizing industrial structure and combining protection with governance in order to promote a water resource quality development.

摘要： 水资源高质量利用是可持续发展理念下解决水危机的重要方式。开展水资源配置研究，不仅可以提供缓解水资源供需矛盾的方法，推动水资源长效利用；同时也可以为社会经济发展保驾护航，支撑经济社会高质量发展。本文构建“三条红线”控制下多目标区域水资源优化配置模型，并以南京市为例分析其当前水资源供需情况，同时采用多目标粒子群算法对模型求解，获得规划年的水资源优化配置方案。在2030年，在三条红线约束下南京市可供水量为34.41亿m³，缺水率约为8.22%。工业、农业以及生活用水仍占据水资源配置主流，环境用水配置增长较快。COD和氨氮得到较好控制，较为理想的实现了经济效益目标、社会效益目标、环境效益目标的三者均衡发展。根据南京市水资源优化配置结果，笔者提出供需协调、优化产业结构、“护”“治”结合以促进水资源高质量发展的优化建议。
