【摘要】 对短期围封下呼伦贝尔草甸草原的植物群落特征及物种多样性的研究表明:随着围封年限的增加,群落盖度、高度、物种丰富度随之增加;物种多样性指数与群落高度、密度、盖度和地上生物量呈线性或二元结构函数式关系。更多还原

【Abstract】 The influence of short-term enclosure on the community characteristics and species diversity was carried out on meadow steppe in Hulunbuir.The results showed that the coverage,density,species diversity of community increased with enclosure time.The species diversity index was linear or quadratic function relationship with height,density,coverage and biomass of community.更多还原
