摘要
建植混播人工草地是退化草地恢复的有效措施,混播牧草品种之间对资源竞争使一方占据群落优势地位,另一方逐渐消退,导致人工草地群落结构不稳定,最终退化。开展人工草地种间竞争研究对草地生态恢复有重要意义。文章运用CiteSpace进行文献计量分析,综述人工草地种间竞争的研究方法、评价体系、竞争模型以及研究现状,综述草地竞争国际研究现状、知识图谱、研究热点和发展趋势,归纳了人工草地从建植到稳定的影响因素以及人工混播牧草对生态因子的竞争强度,展开人工草地种间竞争研究展望。
Constructing and planting mixed sown artificial grassland is an effective measure for the restoration of degraded grassland;the competition for resources among mixed sown forage varieties will make some species occupy the dominant position of the community,while the others will gradually fade away,leading to an unstable artificial grassland community until to a degraded community.The study of interspecific competition in artificial grassland has significance for grassland ecological restoration.The article uses CiteSpace software to summarize the research methods and evaluation system of artificial grassland interspecific competition,recites the competition model and research status,overviews of the current situation knowledge map,researches hotspots and development trends of grassland competitive international research,summarizes the artificial grass from planting factors that influence the stability of the artificial mixed seeding grass on the competitive strength of ecological factors,and proposes the research of recast propose for the development of artificial grassland interspecific competition.
