岩溶地区由于其独特的地表地下结构，地表水资源较为缺乏。如何充分合理地利用岩溶地区宝贵的水资源，对当地的经济发展有着重要的影响。本文以贵州普定后寨地下河流域为例，根据地表、地下水库的不同储水特性，建立了地表地下水库联合优化调度模型。采用本模型调度，可增加保灌面积１７９．２ｈａ，减少弃水１２９×１０４ｍ ３。充分提高了岩溶地区水资源的利用效率。
Karst area due to its unique surface underground structure, the lack of surface water resources. How to make full and reasonable use of the precious water resources in karst areas has an important influence on the local economic development. Taking the Houzhai underground river basin in Puding County of Guizhou Province as an example, a joint and optimal operation model of surface and underground reservoirs has been established according to different water storage characteristics of surface and underground reservoirs. Dispatching with this model can increase the area of irrigation and irrigation 179.2ha and reduce the waste water 129 × 104m 3. Fully improve the utilization efficiency of water resources in karst areas.
