摘  要:“黑土滩”是高寒地区一种特殊且严重的草地退化现象,严重威胁区域生态安全和草地畜牧业健康发展。文章分析了“黑土滩”定义和分类存在的局限,提出了一个综合的“黑土滩”定义,并以“黑土滩”发生区域的主要植被类型和导致黑土滩形成的主要成因为分类基础,结合构建的“黑土滩”综合评价指数将“黑土滩”划分为3类9种4个级别。并提出了未来需要进一步拓展和深化的研究方向,为“黑土滩”定义和分类以及恢复相关技术研发提供了一个新的视角和思路。“Black soil beach” is a special and serious grassland degradation phenomenon in high-altitude areas,which poses a serious threat to regional ecological security and grassland animal husbandry development.This paper analyzes the limitations of the definition and classification of “black soil beach”,proposes a comprehensive definition of “black soil beach”,and establishes a classification system based on the main vegetation types and causes of “black soil beach” in the occurrence area,combined with the construction of “black soil beach” comprehensive evaluation index(BGDI),which divides “black soil beach” into 3 categories,9 types and 4 levels.In addition,this paper also puts forward the future research directions that need to be further expanded and deepened,providing a new perspective and idea for the definition and classification of “black soil beach” and the development of related technologies for restoration.
