针对高强度人类活动作用下海河流域水循环的"自然-人工"二元特性,开发了流域二元水循环模型(简称"二元模型").二元模型由分布式流域水循环模型(WEP)、水资源合理配置模型(ROWAS)和多目标决策分析模型(DAMOS)3个模型耦合而成.针对各模型的优势与不足,提出了两层耦合的技术路线,以实现统筹考虑水资源、宏观经济与生态环境的流域水资源综合管理分析的功能.WEP、ROWAS和DAMOS分别采用11752个、125个和8个计算单元对海河流域进行划分,在获取各类输入参数后,应用二元模型对海河流域进行了分析计算与模型验证.结果表明,所建立的二元模型对径流过程、入海水量以及地下水流场等均具有合理的模拟精度,模型得到验证,可望用作海河流域水资源规划与管理的情景分析工具.
針對高彊度人類活動作用下海河流域水循環的"自然-人工"二元特性,開髮瞭流域二元水循環模型(簡稱"二元模型").二元模型由分佈式流域水循環模型(WEP)、水資源閤理配置模型(ROWAS)和多目標決策分析模型(DAMOS)3箇模型耦閤而成.針對各模型的優勢與不足,提齣瞭兩層耦閤的技術路線,以實現統籌攷慮水資源、宏觀經濟與生態環境的流域水資源綜閤管理分析的功能.WEP、ROWAS和DAMOS分彆採用11752箇、125箇和8箇計算單元對海河流域進行劃分,在穫取各類輸入參數後,應用二元模型對海河流域進行瞭分析計算與模型驗證.結果錶明,所建立的二元模型對徑流過程、入海水量以及地下水流場等均具有閤理的模擬精度,模型得到驗證,可望用作海河流域水資源規劃與管理的情景分析工具.

A dualistic hydrological cycle model (abbreviated as dualistic model) is developed orienting the natural-artificial dualistic characteristic of hydrological cycle in the Haihe River Basin (HRB) under the strong impacts of human activities, which consists of the distributed watershed hydrological model (WEP), the water resources rational allocation model (ROWA) and the multi-objective decision model (DAMOS). A two-layered coupling technique is adopted to realize the function for integrated water resources management analysis. The HRB is respectively partitioned into 11 752, 125 and 8 application units for the execution of WEP, ROWA, and DAMOS. The dualistic model is calibrated and validated using the observations from the HRB. The result shows that the simulated evapotranspiration, river flow, flow discharge into the sea, and groundwater flow filed compare well to the observations, which demonstrates the potential of using the dualistic model for scenario analysis of water resources planning and management in the HRB.
