1) hummock form
踏头形态差异
1.
Based on the plant richness, the number of hummock and the coefficient of variation of the hummock forms, we analyzed the mechanism of the changes of surface roughness.
以东北区典型泥炭沼泽—金川泥炭沼泽为例,考虑地表坡度影响,用链条法对不同群落中糙度系数指标进行计算,并以泥炭沼泽中物种多样性、踏头个数以及踏头形态差异变率系数为主,初步分析泥炭泥泽地表糙度的变化机制,结果表明:在芦苇-臌囊苔草群落、臌囊苔草群落和油桦-臌囊苔草-泥炭藓群落三个植物群落中,糙度系数指标的变化与群落中物种丰富度和生物多样性变化相一致;糙度系数变化与踏头个数呈负相关关系,与踏头形态差异变率系数呈正相关关系。
2) morphological variation
形态差异
1.
In this paper four populations of Stipa krylovii in Inner Mongolia steppe,collected from Xinhot,West Xilinhot,East Xilinhot,Bayanwula,respectively,were used for the study of their morphological variations.
对内蒙古中东部草原分布的克氏针茅进行了种群内和种群间的形态差异分析。
2.
australasicus,four multivariation analysis methods were used to comparably investigate the morphological variations among the three populations——two populations of S.
应用4种数理统计方法,采用19个形态比例性状,对东黄海鲐鱼(包括日本鲐的五岛西部种群和东海西部种群,澳洲鲐)3个群体形态差异进行研究。
3.
The results showed that there were no significant morphological variations between males and females, while the morphological parameter of the ratio of body length and level distance from the beginning of body to the beginning of ventral was significantly different.
本文利用数理统计手段研究南四湖大鳞副泥鳅雌雄个体形态差异,结果表明大鳞副泥鳅雌雄个体形态整体差异不显著,但体长/吻腹长指标差异显著;1龄鱼、3龄鱼雌性个体体长、体重大于雄性个体,2龄鱼则呈相反趋势;t检验表明,仅3龄鱼雌雄个体间体长、体重差异显著。
5) Morphological variation of populations
种群形态差异
6) Agronomic trait difference
形态生育差异
