5通过对云南松树轮样本的年代学和气候学分析可知，在昆明地区可以利用云南松进行树木年轮研究，所建立的树轮宽度指数年表中自回归年表的敏感性较高，但去趋势序列年表反映的群体信息更多；轮宽与气候要素的显著相关关系，使利用轮宽变化的指数年表重建气候变化的历史过程具有可能性。

As such, it rejects not only radiometric and isochron dating of the age of the Earth, arguing that they are based on debatable assumptions, but also approaches such as ice core dating and dendrochronology, which make the barest of assumptions of uniformitarianism, and which hint that the Earth is far older than the Ussher-Lightfoot Calendar suggests.
