Abstract

There is a severe conflict between water resource exploitation and protection of the aquatic environment of lakes with rapid urbanization. Sustainable water resource utilization is urgent for sustainable development. The present study introduced a progressive operational scenario analysis (POSA) method for water resource regulation in lake basins. The application processes of POSA in Dianchi Lake, Erhai Lake and Fuxian Lake were described in detail. The effectiveness of the POSA method and scenario analysis method in achieving sustainable water resource utilization were compared and analysed, and the improvement in the efficiency of water resource utilization in lake basins due to the two methods was discussed. The results showed that implementation of POSA can effectively achieve sustainable water resource utilization in Dianchi Lake, Erhai Lake and Fuxian Lake and reduce the aquatic environmental pressure. Compared with business-as-usual, this method reduced the water use efficiency indicators of Dianchi Lake, Erhai Lake and Fuxian Lake by 2%–8%, 1%–25% and 8%–35%, respectively, and the water environmental pressure in Dianchi Lake, Erhai Lake and Fuxian Lake decreased by 28.51%, 29.70% and 69.39%, respectively. POSA has been proven to be an excellent tool for managing the aquatic environments and regulating water resources in lake basins.

运用渐进操作场景分析实现流域水资源的可持续利用

摘要

水资源的开发与快速城市化对湖泊水生环境的保护之间存在着严重的冲突。水资源的可持续利用对于可持续发展至关重要。本研究介绍了一种用于湖泊流域水资源调节的渐进式操作情景分析（POSA）方法。详细介绍了POSA在滇池，Er海和抚仙湖的应用过程。比较和分析了POSA方法和情景分析方法在实现水资源可持续利用方面的有效性，并讨论了由于这两种方法所带来的湖盆水资源利用效率的提高。结果表明，实施POSA可以有效地实现滇池水资源的可持续利用，减轻hai海和抚仙湖的水生环境压力。与常规方法相比，该方法将滇池，Er海和抚仙湖的用水效率指标分别降低了2％–8％，1％–25％和8％–35％，以及水环境滇池，Er海和抚仙湖的压力分别下降了28.51％，29.70％和69.39％。事实证明，POSA是管理湖泊水域环境和调节水资源的绝佳工具。分别为70％和69.39％。事实证明，POSA是管理湖泊水域环境和调节水资源的绝佳工具。分别为70％和69.39％。事实证明，POSA是管理湖泊水域环境和调节水资源的绝佳工具。
