摘要
本文介绍了WEP-L模型在黄河流域的应用情况,包括输入数据处理、参数估算与模型验证,以及广义水资源初步评价成果。应用结果表明,所提出的模型和方法,能够评价径流性水资源、生态系统利用的雨水资源及其构成,能够分析在强烈人类活动影响下黄河流域广义水资源与构成所发生的显著变化。1985年及2000年下垫面条件下的水资源评价结果对比分析表明,水土保持、农田建设及取用水活动等引起的下垫面条件变化,使得流域狭义水资源总量减少(地表水减少但不重复地下水增加)、广义水资源总量增加,水土保持及农田建设增加的降水高效利用量远大于其减少的径流性水资源量。最后讨论了成果对黄河流域水安全战略和水资源可持续高效利用的一些启示。
Applications of WEP-L model in the Yellow River basin are introduced, including process of input data, parameter estimation and model verification, and the preliminary results of general water resources assessment. The application results illustrate that the suggested model and approach are capable of assessing runoffs-typed water resources and rainfalls-typed water resources utilized by ecosystems, and analyzing the obvious changes of general water resources and various components in the basin under the impacts of strong human activities. The contrast of the assessment results under the land cover conditions of 1985 and 2000 reveals that land cover condition changes caused by water and soil conservation, cultivated land construction and water taking activities make the special water resources in the basin decreased （surface water resources deceased but the non-overlapped groundwater resources increased） and the total general water resources increased, and the high-efficiently utilized rainfalls increased much more than the decreased runoffs-typed water resources. Last, the paper discusses the hints of the research results to water safety strategy in the Yellow River basin and sustainable and efficient development of water resources in China.
