以生物群落为原则的高寒草地分类方法的改进

Improvement of Alpine Grassland Classification Methods Based on Biotic Community

生物群落特征能够反映自然界中生物多样性的变化,有助于维持生态平衡,对于草地的结构和功能有着重要影响。文章通过综述草地分类方法研究进展、问题以及植物群落、啮齿类动物群落和微生物群落在草地类型划分中的应用,重点关注对二级分类指标“型”的改进,以生物群落为原则,将植物群落、啮齿类动物群落和微生物群落的综合特征作为草地类型的判定依据,构建了新的高寒草地分类体系,使草地分类法的结果更深入、更准确、更全面。

Characteristics of biotic community can reflect the changes of biodiversity in nature,help to maintain ecological balance,and have an important influence on the structure and function of grasslands.By summarizing the research progress and problems of grassland classification methods and the application of plant communities,rodent communities and microbial communities in the classification of grassland types,this paper focuses on the improvement of the second-level classification index“type”.Based on the principle of biotic community,the combined characteristics of plant communities,rodent communities and microbial communities were taken as the basis for determining grassland types,and a new alpine grassland classification system was constructed,which made the results of the grassland classification method more in-depth,more correct and more comprehensive.
