摘要
分析了草地类型生态系统退化的现状、原因及其恢复途径 ,提出人工草地的建立是恢复退化天然草地的有效途径 ;综述了人工草地的研究进展 ,提出高效型人工草地的建立是缓解草原压力、促进牧区可持续发展的良策 ;从高效角度出发 ,种植饲用玉米可以作为建立人工草地的一个有益尝试 .
This paper analyzed the degradation actuality of natural grassland,its reasons and corresponding restoration ways.Natural restoration is the easiest way,but it is very slow.The establishment of some artificial grassland is the most effective way to lessen the oppressiveness of natural grassland.The research advances on artificial grassland were summarized,and the ways for promoting the sustainable development of pasturing area were suggested.Considering the high productivity,planting forage maize may be an available attempt in Hunshandak Sandland.
