The mass spectrometric investigations of carbon isotope composition of glucose received from α-cellulose samples derived from Scots pine (Pinus sylvestris L.) growing in Niepołomice Forest were the main aim of this study. The annual rings covered the time span from 1950 to 2000. α-Cellulose samples were extracted from increment cores of four representative trees, and then acid hydrolysis was performed. The number of sunshine hours, thermal and pluvial conditions of the growing season and in the preceding months had a significant effect on pine. Also non-climatic factors, most likely by industrial pollution signal, have been recorded in the isotopic composition of glucose. The relationship between climatic conditions, carbon dioxide emission and annual tree-rings carbon isotopic composition was analysed, using methods of correlation and response function, and multiple regression function.
本研究的主要目的是对取自生长在涅波洛米奇森林的苏格兰松（Pinus sylvestris L.）α-纤维素样品中的葡萄糖碳同位素组成进行质谱研究。年轮覆盖了1950年至2000年的时间跨度。从四棵代表性树木的生长芯中提取α-纤维素样品，然后进行酸水解。生长季节及前几个月的日照时数、热量和降雨条件对松树有显著影响。在葡萄糖的同位素组成中也记录到了非气候因素，很可能是受工业污染信号的影响。利用相关分析、响应函数和多元回归函数等方法，分析了气候条件、二氧化碳排放与树木年轮碳同位素组成之间的关系。
