摘要
本文用方差分析法对岷山和邛崃山大熊猫头骨和牙齿的不同指标进行分析比较,发现邛崃山大熊猫体型显著地大于岷山大熊猫体型,作者对其差异原因进行了分析,认为可能与两山系大熊猫微量元素含量差异等有关。
Since 1984-1989, we have got 29 and 18 skulls of thegiant panda from the Mins-han and Qionglaishan Mountains respectively. The skulls were measured and then we input data to IBM computer to do variance analysis test. Through test for different ite-ms between the Minshan and Qionglaishan Pandas, it can be seen that there are significant differences in condylobasal length, rostral length, palatal length and joint length of lower jaw between the two pandas. This means that the tody size of Qionglaishan pandas is much bigger than that of Minshan pandas. The results observed directly in the field also prove this point. After further analysis, some results are as follows:
1. There are significant differences in skull length between the two pandas such as condylobasal, rostral length, no differences in width such as zygomatic
2. There are significant differences in teeth width between the two pandas no dif-ferences in teeth length.
3. There are shgnificant differences in premolar length only, no differences in molar cheek length.
4. There are significant differences in outer distance between the same left and right tooth, no differences in inner distance.
The causes of the differences were discussed.
