中文摘要: 我国草原总面积为392.8万平方公里,约占国土面积的40.9%,是国家生态安全的重要绿色屏障,也是农牧民赖以生存的主要生产资料。然而,自20世纪80年代开始,我国草原发生了大面积、不同程度的退化。迄今,“局部好转、整体恶化”的态势没有得到根本扭转,这已成为制约我国生态文明建设和社会经济发展的主要瓶颈。文章分析了我国草原恢复与保护的现状及存在的问题,提出草原恢复与可持续管理的对策,旨在为我国草原的恢复、保护和可持续利用提供参考。
Abstract:The area of grassland in China is about 392.8 million hm2, covering 40.9% of land surface of China. Grasslands not only serve as important green barriers for national ecological security but also as basic means of production for local farmers and herders. However, the grasslands in China have been unevenly deteriorating since 1980s in large areas. To date, the overall condition of grasslands in China remains worsening, with some area getting better. Such a situation severely constrains the developments of ecological civilization and social economy in China. Here, we analyze the current state and issues in grassland restoration and conservation and suggest some countermeasures, aiming to restore, conserve, and sustainably use the grasslands in China.
