【摘要】 本文根据流域各河流水系形成的自然生态环境属性及河道取水工程设施节点,采用Penman-Monteith生态需水定额和卫星遥感面积识别及水文年内展布综合方法,分析评估白杨河流域现状敏感区生态环境需水量和河流生态基流及其调控断面。分析结果可为流域生态环境保护提供参考依据。更多还原

【Abstract】 Following the natural eco-environmental attributes formed by river systems in the basin and the nodes of river water intake engineering facilities, this paper uses Penman-Monteith ecological water demand quota, satellite remote sensing area identification and comprehensive methods of hydrological year distribution to analyze and evaluate the eco-environmental water demand in sensitive areas of the basin status quo, river ecological base flow and its regulation section in Baiyang River basin. The analysis results can provide reference basis for watershed ecological environment protection.更多还原
