汉江中下游河道基本生态需水与生径比分析
Analysis on basic eco-water demands and REF in mid-lower reaches of Hanjiang River
摘要
Abstract
The calculation of eco-water demand relates to the ecological restoration and coordinated development between re-gional economy and environment, and eco-water demand is also the guarantee of maintaining the balance of ecosystem. To re-duce the error by a single method, the paper uses nine kinds of hydrological methodologies such as 7Q10, NGPRP and Texas methods to compute the basic eco-water demands in the mid-lower reaches of Hanjiang River, and classifies the calculated re-sults with the Montana method to obtain rational eco-water demands based on the Montana method. Meanwhile, based on many concepts of eco-water demands, the paper presents a concept of REF ( the ratio of the eco-water demands to stream flow) , a parameter reflecting the dynamic nature of eco-water demands, and by Montana method, Texas method, monthly guaranteed fre-quency method and its improved method, the REF in flood season and non-flood season in the mid-lower reaches of Hanjiang River are calculated.关键词
