| 摘 要： | 研究了内蒙古典型草原天然割草场的７６种植物留茬高度与损耗率的相关，结果表明：多数植物种群留茬高度与损耗率之间的关系为线性关系，符合ｙ＝ａ＋ｂｘ回归方程；少数植物种群为对数相关，符合ｙ＝ａ＋ｂｌｎｘ回归方程，这与不同植物的形态特征有关。

| Abstract: | eals with the relationships between stubble height of populations and loss proportion of the76 species, The results are shown as follows: 1) It was linear correlation for the most species, ac-cording with the regression equation =a bx; 2) It was logarithmic correlation in the fewspecies, which accords with the regression equation =a blnx. It is due to the morphologicalcharacteristics of the various plants. |
