摘要
河流生态流量确定是近年来国内外研究的一个热点。文章通过天然径流序列分析、水资源演变情势分析,选取当前国内外通用的水文学研究方法,如Tennant法、Qp法,对木兰达河生态需水量进行确定并分析研究。结果表明:木兰达河降水主要集中在6-9月,丰、平、枯三个水期差异明显,汛期、非汛期季节性变化较大,应采用Qp法计算结果作为本次生态流量目标。该研究可对木兰达河流域水资源管理和保护提供科学依据。
Determination of river ecological discharge is a hot topic in recent years.Through natural runoff sequence analysis and water resources evolution analysis,the current hydrology research methods used at home and abroad,such as Tennant method and Qp method,were selected to determine and analyze the ecological water demand of Mulinda River.The results showed that the precipitation of Mulda River mainly concentrated in June to September,and the difference was obvious in the three water periods of abundance,flat and dry,and the seasonal variation was great in the flood season and non-flood season.The results of Qp method should be used as the target of ecological discharge this time.This study can provide scientific basis for water resources management and protection in the Mulanda River basin.
