基于生态优先的渝西地区水资源配置研究

重庆市渝西地区自产水资源短缺,河流生态脆弱,水资源和水环境承载能力不足以支撑区域经济社会可持续发展,水资源配置格局亟需优化。因此,基于MIKE BASIN软件平台建立了渝西水资源配置模型,模拟对象包括区内主要水源工程、用水户和河流;然后从生态基流需水、水生生物需水、基本自净功能需水3个方面分析了河流控制断面生态环境需水量。在此基础上提出了在退还现状生产生活挤占的生态用水和区内水资源优先满足生态环境需水的前提下,以提水利用嘉陵江、长江过境水为主要解决生产生活缺水并补充河流生态环境用水的水资源配置方案。

Water resources allocation of Western Chongqing based on ecology priority

The water resources allocation of Western Chongqing region needs to be optimized because the insufficient self-yielded water resources and vulnerable water environment can't support the regional sustainable economic and social development. A water resource allocation model was established based on MIKE BASIN to simulate the main water supply projects, water users and rivers. Eco-environmental water demand of river control sections was calculated from three aspects: ecological basis flow demand, aquatic organism flow demand and self-purification flow demand. On the premise of returning ecological water occupied by domestic and industry and giving eco-environmental water demand the priority of water supply, a water resources allocation mode was put forward, in which domestic and industry water demand was met by pass-by water resources lifted from Yangtze River and Jialing River.
