基于改进湿周法的贾鲁河河道内生态需水量计算
Study of ecological instream flow requirement of Jialu River based on improved wetted perimeter method
摘要
Abstract
According to the actual conditions along the Jialu River, we selected the Zhongmou and Fugou Hydrological Stations as the control sections, and calculated the ecological instream flow requirements of the Jialu River in different frequency years using three kinds of improved wetted perimeter methods, including the slope method, the curvature method, and the multi-objective evaluation method. The results show that the calculated ecological flow requirement is greatest when using the multi-objective evaluation method (r=2), and least when using the curvature method. It is more reasonable to use the multi-objective evaluation method (r=2) to calculate the ecological flow requirement of the Zhongmou section, and to use the slope method to calculate the ecological water requirement of the Fugou section.关键词
