红原县白河瓦切镇塔林段水生态保护方案之浅见

A Preliminary View on the Water Ecological Protection Plan for Talin Section of Waqie Town along the Baihe River in Hongyuan County

黄河上游高寒草甸草原小流域生态环境脆弱,部分小流域因受过度放牧、草皮层冻融剥离、河水冲刷等因素影响出现了河流两岸草甸退化、水土流失严重、水源涵养能力降低等现象。阐述了针对该区域小流域出现的上述水生态环境问题进行的研究,结合阿坝州红原县黄河流域白河瓦切镇塔林段水生态保护项目,提出了“草甸修复、生态护岸、封禁治理、湿地建设、水污染防治”的综合治理思路,并给出了相应的治理方案。该方案落实后,可以起到在维持该地区原有生态景观的同时修复河流两岸受损草原的生态系统,改善水环境质量,提高当地小流域水土保持及水源涵养能力的作用。

The ecological environment of the alpine meadow grassland watershed in the upper reaches of the Yellow River is fragile,and some of the small watershed are affected by overgrazing,thawing and freezing stripping of grass layer,river erosion,etc.,resulting in meadow degradation,serious soil and water loss,and reduction of water conservation ability.This paper expounds the research on the above-mentioned water ecological environment problems in the small watersheds in this region.Combined with the Water Ecological Protection Project of the Talin section of Wache Town along the Baihe River in the Yellow River Basin in Hongyuan County,a comprehensive governance idea of"meadow restoration,ecological bank protection,management of closing mountains and banning logging,wetland construction,and water pollution prevention and control"is proposed and a corresponding governance plan is given in the paper.After the implementation of this plan,the original ecological landscape of the area can be maintained while repairing the damaged grassland ecosystem on both sides of the river,improving the water environment quality,and enhancing the soil and water conservation and headwater conservation capacity of local small watersheds.
