【摘要】 对采自南京太平门的雪松〔Cedrusdeodara (Roxb .)Loud .〕树轮α 纤维素的δ13 C进行分析 ,结合江苏气象台的气象记录 ,建立树轮δ13 C与气候各要素的回归方程 ,并进行了气候重建 ,重建值与观测值吻合较好 ,表明南京地区树轮α 纤维素稳定碳同位素与 5～ 7月平均降雨量及 5～ 9月平均气温显著相关 ,重δ13 C对应于 5～ 7月的少雨和 5～ 9月的高温 ,轻δ13 C对应于 5～ 7月的多雨和 5～ 9月的低温 ,在一定程度上反映了东亚季风盛行区树木生长与水热组合的关系。更多还原

【Abstract】 The δ\+\{13\}C on α\|cellulose of \%Cedrus deodara \%(Roxb.) Loud. tree rings are analysed in Taipingmen area, Nanjing. Combining with the records of Jiangsu Meteorological Station, the regressional equations of δ\+\{13\}C and climatic factors are constructed, then the parameters are reconstructed. The calculated values are identical with the true values. The results indicated that δ\+\{13\}C values of tree ring α\|cellulose in Nanjing area show significant correlation with air temperature from May to September and precipitation rate from May to July. The heavy δ\+\{13\}C is corresponding to the little precipitation and high temperature, the light δ\+\{13\}C is corresponding to the increasing precipitation and low temperature. To a certain extent, which inferred the relation between tree growth and water\|temperature in East Asian Monsoon prevailing area.更多还原
