丹江干流(河南段)生态流量研究

Research on the Ecological Flow of Danjiang Main Stream (Henan Section)

由于对生态流量缺乏重视,丹江干流的水电开发已对下游河道生态造成了严重影响,因此亟需提出生态流量的泄放标准和措施。本文根据荆紫关水文站实测径流资料,主要采用水文学方法对河道进行了生态流量计算。经分析比较,提出了丹江干流电站逐月生态流量的建议值,推荐的生态流量占河道多年平均流量的12.3%~44.0%,并提出了下泄生态流量的保障措施和建议。本文为丹江河南段的水生态保护提供了参考,对保护丹江湿地国家级自然保护区的生态具有一定意义。

Due to little attention to ecological flow, the development of Danjiang mainstream hydropower has seriously affected the downstream river ecosystem. Therefore, it is urgent to propose standards and measures for the discharge of ecological flows. According to the measured runoff data of Jingziguan Hydrological Station, this paper mainly uses the hydrological method to calculate the river ecological flow. After an analysis and comparison, the recommended values of the monthly ecological flow of the Danjiang main stream power station are proposed. The recommended ecological flow rate accounts for 12.3%~44.0% of the average annual flow, and the safeguard measures and suggestions for the discharge of ecological flow are proposed. This paper provides a reference for the water ecological protection of the Danjiang River, and has a certain significance for protecting the ecology of the Danjiang Wetland Nature Reserve.
