摘要/Abstract

摘要： 对新疆托木尔峰地区松树年轮样品的ESR研究表明,其自由基浓度N_g是树木生长速率的指示,它与季节有关。春材的N_g值普遍高于秋材,与气温、降雨量有关,但不是一一对应的关系。年轮的N_g明显地受太阳黑子活动周的影响,随着太阳周而变化,只是峰谷和峰值年要前移或后推1-2年。

关键词: 树木年轮, 自由基浓度

Abstract: Samples of pine tree ring from Mt. Tuomuer region of Xinjiang province were researched using ESR method. The result shows that the free radical concentration N_g is an index of tree growth and relates to the season, and to the temperature and the precipitation. The N_g of spring wood is more than that of autumn. The N_g of wood was prominently influenced by the period of sunspot activity and it varies with the solar period, but the values of peak and valley have been preacted 2-3 years or postponed.

Key words: Tree ring, Free radical concentration
