甘肃藏区主要涉及甘南藏族自治州及天祝藏族自治县,该区域存在着水土流失加重、水源涵养功能减弱、植被覆盖度下降和生物多样性锐减等生态问题。近年来,不断增加的生产建设项目,对本就处于退化状态且自我修复能力很差的草原造成了严重破坏,产生了大量的水土流失。以甘肃藏区天祝县境内松山镇鼎盛松山滩风电场一期工程为例,分析了风电场不同防治分区的水土流失防治技术,重点介绍了草皮剥离、回铺技术和道路截渗水沟技术在该区应用的特殊性。
The Tibetan areas in Gansu mainly involve Gannan Tibetan Autonomous Prefecture and Tianzhu Tibetan Autonomous County. There are ecological problems such as aggravated soil and water loss, water conservation function, decreased vegetation coverage and sharp decrease of biodiversity in this area. In recent years, an increasing number of production and construction projects have caused serious damage to grasslands degraded and poorly self-repairing, resulting in a large amount of water and soil loss. Taking the first phase project of Songshengtan Matsuyatan wind farm in Songshan Town in Tianzhu County of Gansu as an example, the prevention and cure techniques of soil and water loss in different control zoning of wind farms are analyzed. The technology of turf peeling, The particularity of the application of this area.
