摘　　要：本文利用临沂市郯城县新村乡银杏树轮样芯建立了银杏树轮宽度年表,经过对特征值的比较分析寻找更适合进行树轮气候分析的年表——树轮宽度标准化年表,并利用了气候因子与树轮宽度之间的相关关系,建立了气候因子与树轮宽度的函数方程,重建了研究区1878~2017年间10月份的最高温度以及7月份的降水量,并进行气候变化的周期分析。本研究可为了解研究区历史时期的气候变化提供基础参考数据,并对我国东部暖温带地区树轮气候学研究提供有益补充。In this paper, the Ginkgo tree wheel width chronology is established by using the Ginkgo tree wheel sample core in Xincun Township, Linyi City, and after comparative analysis of the characteristic values, the chronology-tree wheel width standardized chronology is more suitable for tree wheel climate analysis. Using the correlation between climate factors and tree wheel width, the function equation between climate factor and tree wheel width was established, the highest temperature in October and July precipitation in the study area were reconstructed, and the periodic analysis of climate change was carried out. This study can provide basic reference data for understanding the historical climate change in the study area, and provide a useful supplement for the study of tree ring climatology in the eastern warm temperate zone of China.
