摘要
祁连山是中国西部重要生态安全屏障,是黄河流域重要水源地,是中国生物多样性保护优先区域。但祁连山也是一个生态极其脆弱的区域,生态系统易受自然条件的影响,承载力低、易破坏、修复能力弱。近年来,为了修复祁连山生态环境,彻底解决祁连山区农牧民脱贫致富,武威市把海拔2800m左右祁连山干旱山区的贫困户,整村搬迁至河西灌溉区域,实现整体脱贫。干旱山区移民搬迁退耕地如何恢复植被,我们在武威市古浪县十八里堡乡铁柜山村移民搬迁区退耕地,进行了12个优质牧草品种的引种栽培试验,对其生长特性、产量等相关性状进行了栽培试验研究,筛选出适宜祁连山移民搬迁干旱山区种植的优质牧草品种,为大面积移民搬迁区退耕地种植提供牧草品种和技术保障。
Qilian Mountain is an important ecological security barrier in western China. And it is an important water source of the Yellow River and also a priority area for the protection of China's biodiversity. However, it is an area with extremely fragile ecology. The ecosystem is vulnerable to natural conditions, and its carrying capacity is low,repair ability is weak,and easy to destroy. In recent years, in order to repair the ecological environment and completely help the farmers and herdsmen in Qilian Mountain get rid of poverty and become rich, Wuwei City has relocated the poor households in the arid mountainous area of Qilian Mountain at an altitude of 2,800 meters to the irrigation area of Hexi to realize the overall poverty alleviation. How to restore vegetation by relocating and returning cultivated land in arid mountainous areas? We arrived at the Tiegui village of Shilibao Township in Wuwei, conducted 12 experiments on the introduction and cultivation of high-quality pasture species, and do research on their growth characteristics, yield, and other related traits. Finally, the high quality forage varieties suitable for the relocation of Qilian Mountain immigrants in arid mountainous areas are selected, which will provide varieties and technical guarantees for the forage cultivation of arable land in large resettlement areas.
