近300年秦巴山区树轮数据集

近300年中国南北过渡带--秦巴山区不同区域的树轮重建气候变化数据集，由专业人员按照气象行业标准《树木年轮气候研究树轮采样规范》，通过采样、宽度测量、气候重建等获得，重建得到秦巴山区过去300余年气候变化情况，数据资源包括年份和重建气温两种要素，共计2629行，完全开放共享。

Tree-ring-based climate change reconstruction dataset for multiple regions of the Qinling-Daba Mountains, the north-south transitional zone of China, spanning the past nearly 300 years. This dataset was developed by professional researchers in accordance with the meteorological industry standard *Specification for Tree-ring Sampling in Dendroclimatological Research*, through processes including sampling, tree-ring width measurement, climate reconstruction and other related works. It reconstructs the climate change conditions of the Qinling-Daba Mountains over the past more than 300 years. The dataset contains two core variables: year and reconstructed air temperature, with a total of 2629 rows, and is fully open for access and sharing.
