摘要:青檀树皮是制造宣纸的主要原材料,为获得较高质量的檀皮并对青檀的人工种植提供理论指导,选取安徽周边青檀分布比较集中的6个省份作为采集样地,比较了各地青檀檀皮纤维长度、宽度以及长宽比,并采用相关性分析和主成分分析法分析了青檀纤维指标与各生态因子之间的联系.结果表明:不同生长环境下,青檀的檀皮纤维长度、宽度及长宽比有显著差异,其中山东青檀寺和安徽泾县的纤维长宽比分别为283.87和229.55,明显高于其他4个地区,檀皮质量较好;相关性分析显示青檀檀皮的质量与各生态因子均呈一定程度的正负相关性,但相关性不显著;主成分分析中,3个主成分的积累贡献率达94.66%,大小顺序依次为温度光照因子>土壤因子>地理位置因子,说明温度光照对青檀的檀皮影响较大.%Pteroceltis tatarinowii Maxim. , the main raw material for manufacturing of rice paper, has a high economic value. In order to obtain high-quality bark of P. tatarinowii and provide theoretical guidance for artificial cultivation of it, this paper selected six prov-inces around Anhui Province where abundant P. tatarinowii distribute, and compared fiber length, width and length-width ratio of P. tatarinowii there. Results showed that the fiber length, width and length-width ratio of P. tatarinowii varied with its growing environ-ments and has a significant difference. The P. tatarinowii in Qingtansi, Shandong Province and Jingxian, Anhui Province all has high quality and its length-width ratio is 283. 8 and 229. 55, respectively, which were obviously higher than that in other four places;Corre-lation analysis showed that the quality of P. tatarinowii bark has a certain degree of positive and negative correlation with its various ec-ological factors;the principal component analysis indicated that the accumulated contribution rate of three principal components reached 94. 66%, and the rank of each factor for the accumulated contribution rate from better to less was:temperature-light factor, soil factor and location factor, which manifested that the temperature-light factor had the largest effect on the quality of P. tatarinowii.
