摘　　要：根据腹甲形态以及背甲与腹甲的闭合程度等特征,将大别山区黄缘闭壳龟分为两个自然种群,对其中一个自然种群的形态生物学特征进行研究报道。该自然种群的形态生物学特征为腹甲中部较平,背甲与腹甲完全闭合不紧密,头部、四肢可部分露出,可量性状研究表明,背甲长/背甲宽、背甲长/腹甲长、背甲宽/腹甲宽的统计分析分别为:1.37±0.06、1.04±0.02、1.30±0.04。背甲长与腹甲长的回归方程为Y=1.0512X-1.3141、背甲长与体高的回归方程为Y=0.4665X+0.6157,线性相关极其显著。体重与背甲长、体重与背甲宽、背甲宽与腹甲宽等存在着比较显著的线性关系。而年龄与体重(相关系数为r=0.3640)不存在明显的线性相关性。The Cuoraflavomarginata Gray of Dabieshan region is divided into two natural populations according to characteristics of the breastplate shape as well as the breastplate and the carapace closed degree and so on. The shape biology characteristic of one natural population is reported in this article. This kind of natural population＇s shape biology characteristic is： middle the breastplate is even, the breastplate and the carapace is not completely closed, the forehead and the four limbs may partly reveal. The statistical analysis indicates that the length of carapace/the width of carapace, the length of carapace/the length of breastplate, the width of carapace/the width of breastplate are 1.37 ± 0.06, 1.04 ±0.02, 1.30 ± 0. 04 respectively. The simple linear regression equation of the length of carapace to the length of breastplate is Y = 1. 0512X - 1. 3141. The simple linear regression equation of the length of carapace to the body height is Y = 0. 4665X ＋ 0.6157. The linear correlation is very obvious. There are more obvious linear correlation in： the weight to the length of carapace, the weight to the width of carapace, the width of carapace to the width of breastplate and so on. There was no obvious linear correlation of the age to body weight （ r = 0. 3640）.
