摘要
根据大汶河流域水资源量的形成、多少及其分布主要受地形地貌、地表水系、植被、地面岩土类型等水文下垫面要素以及降水量大小与分布的影响等特点 ,在利用 GIS建立水资源计算与评价模型的基础上 ,分析了大汶河流域水资源分布特征与形势并提出了对策意见 .
Hydrologic basement elements such as topography and landforms, surface water system, vegetation, rock and soil, as well as precipitation are principal factors which affect forming, quantity and distribution of water resources in Dawenhe River Basin.The water resources calculating model is set up based on GIS(Geographic Information System). The strategy on water resources is analyzed, and the counter measures are preliminary put forward.
