Study on Ecological Flow Estimation and Ecological Restoration Safeguard Measures in Chaobai River
摘要
Abstract
In order to protect and rehabilitate the health of the riverine ecosystem in the Chaobai River,the Indicators of Hydro-logic Alteration method (IHA) and Range of Variability Approach (RVA) were used to calculate the characteristics of hydro-logical indices in 5 groups including the average streamflow,extreme value and its occurring time of streamflow, frequency and duration of pulse flow, and variation rates of streamf low based on the daily streamf low data at the Daiying and Xiapu hydrologi-cal stations from 1956 to 2002. The hydrological indices were compared between two time periods. The first one was from 1956 to 1974,which was characterized by little effects from human activities; whereas the second one was from 1975 to 2003,which was characterized by intense effects from human activities. The differences between the actual value and target range of stream-flow were analyzed for the intense human activities time periods. Furthermore, this paper proposed some specific safeguard measures for achieving the restoration objectives.关键词
