The purpose of the research was done for the reconstruction of the climatic change of past 500 years in northern Hokkaido by using Picea glehnii of cool-temperate zone.In the change of annual tree-ring width of the obtained Picea glehnii, the similar time change was admitted the serpentine soil in the wetland soil. The estimated value of the climatic change of the past 300 years in northern Hokkaido which had been compared with other proxy climatic records. Because many of obtained samples were annual tree-ring numbers of 300, the climate reconstruction became past 300 years, An initial purpose was not achieved in the result.However, dendrochronological technology of that have so far been considered difficult to do, a past climate is expected to annual tree-ring width of the Picea glehnii which grows to Hokkaido from the record of the same time change as can the contribution to the climate reconstruction.The plan of the next stage schedule to advance the research aiming at the climate reconstruction of the past 500-1000 years tuned to the world climatic change.

本研究以寒温带云杉为研究对象，对北海道北部近500年来的气候变化进行了重建。所得云杉年轮宽度的变化中，湿地土壤中蛇形土的年轮宽度也有相似的时间变化。将北海道北部近300年的气候变化估计值与其他代用气候记录进行比较。由于获得的样本多为年轮数300的年轮数，气候重建变成了过去300年，结果没有达到最初的目的。然而，迄今为止，树木年代学技术一直被认为是难以做到的，从同一时间变化的记录中，可以预测北海道生长的云杉的年轮宽度的过去气候变化，并可以对气候重建做出贡献。下一阶段的计划是推进以世界气候变化为导向的500-1000年气候重建为目标的研究。
