四川阿坝州作为长江、黄河的重要水源补给区，面临着湿地萎缩、草原沙化等生态问题。为了保护黄河上游的生态环境，阿坝州采取了多种措施，包括生态湿地修复和草原沙化治理。通过建设生态拦水坝、采用先进技术修复湿地，以及实施防沙治沙项目，阿坝州有效地恢复了湿地的生态功能，增加了湿地的蓄水量，并显著提高了草原的盖度。
在若尔盖县，通过建设小型拦水坝和微型拦水坝，湿地修复面积达到了11万亩，湿地封禁面积达到了40万亩。在红原县，通过建立防风阻沙林带、种植生物沙障和灌草，沙化土地的植被覆盖度从不足10%提升到了60%以上。此外，当地还加强了沙化治理区的后期管护，引导牧民参与生态保护，实现了从“草原放牧人”到“生态守护人”的角色转变。
阿坝州还统筹山水林田湖草沙系统治理，科学划定了生态保护红线，建立了黄河干支流域生态防护带，有效提升了草原湿地的功能。
在青海省海南州贵南县，通过科学治沙和生态治沙，昔日荒凉的沙漠已经变成了生机勃勃的绿洲。这一转变是几代人共同努力的结果，他们通过种植植被、进行成效调查和卫星定位等手段，确保了治沙成果的可持续性。
这些措施不仅改善了当地的生态环境，也对于保护黄河上游的水源安全和生态平衡起到了重要作用。通过科学管理和持续努力，阿坝州正逐步构筑起一道坚固的绿色生态屏障，为长江、黄河流域的可持续发展提供了坚实的基础。

Sichuan’s Aba Prefecture, as an important catchment area for the Yangtze and Yellow rivers, faces ecological issues such as wetland shrinkage and grassland desertification. To protect the ecological environment of the upper reaches of the Yellow River, Aba Prefecture has taken a variety of measures, including wetland ecological restoration and desertification control of grasslands. By constructing ecological water retaining dams, using advanced technologies to restore wetlands, and implementing sand control projects, Aba Prefecture has effectively restored the ecological functions of the wetlands, increased the water storage capacity of the wetlands, and significantly improved the coverage of grasslands.
In the county of Ruoergai, the restoration area of wetlands reached 110,000 mu through the construction of small and micro water retaining dams, and the area of wetlands under protection reached 400,000 mu. In Hongyuan County, through the establishment of windbreak and sand-resisting forest belts, the planting of biological sand barriers and grass, the vegetation coverage of desertified land has been increased from less than 10% to over 60%. In addition, local authorities have strengthened the post-management of the sand control areas and guided herdsmen to participate in ecological protection, realizing a transformation from “nomadic herders” to “ecological protectors.”
Aba Prefecture has also integrated the systematic management of mountains, rivers, forests, fields, lakes, grasslands, and sand, scientifically delineated ecological protection red lines, established ecological protection belts for the main and tributaries of the Yellow River, and effectively enhanced the functions of grassland wetlands.
In Haixi Prefecture of Qinghai Province, in the county of Guilin, through scientific and ecological sand control, the once barren desert has turned into a flourishing oasis. This transformation is the result of generations of efforts, ensuring the sustainability of the sand control achievements through the planting of vegetation, effectiveness surveys, and satellite positioning.
These measures not only improve the local ecological environment but also play a significant role in protecting the water source safety and ecological balance of the upper reaches of the Yellow River. Through scientific management and continuous efforts, Aba Prefecture is gradually building a strong green ecological barrier, providing a solid foundation for the sustainable development of the Yangtze and Yellow river basins.
