选择分布在全国6省1市的11个种群青檀为材料，利用冗余分析法（ redundancy analysis， RDA）对檀皮质量指标（纤维素、木质素、戊聚糖含量和纤维形态）与青檀采集地生态环境因子（土壤pH、有机质、矿质元素以及气候条件）之间的关系进行研究。结果表明：青檀多生长在有机质较多、高钙、低磷的土壤中；生长在不同环境中的青檀檀皮质量有显著差异，纤维素含量和纤维长度受环境影响程度较高；纤维素含量主要受土壤速效磷、土壤有机质、年均温、无霜期、纬度的影响，而纤维长度主要受土壤速效钾的影响。总体而言，低纬度地区种群的檀皮质量比高纬度地区种群的高，其中贵州安龙、云南罗平、安徽泾县的檀皮纤维素含量较高，纤维长度较长，木质素含量较低，檀皮质量最好。

In the paper, the relationship between the bark qualities of wingceltis ( Pteroceltis tatarinowii) and ecological environment factors in the collecting locations was determined by redundancy analysis( RDA) . The detected bark quality indexes contained cellulose content, lignin content, pentosan content and fiber morphology,while ecological environment factors contained soil pH, organic matter, mineral elements and climatic conditions. Wingceltis in the study was collected from six provinces and one city. The following results were obtained: wingceltis adapted to the environment which was more soil organic matter, higher calcium and lower phosphorus. The bark cellulose content, lignin content, fi?ber length and width in different populations had significant difference, in addition, the cellulose contents and fiber length could be remarkably influenced by climatic and soil factors. Concretely, the bark quality from the populations in Guizhou Anlong, Yunnan Luoping and Anhui Jingxian was the best owing to higher cellulose content, longer fiber length and lower lignin content. Besides, the cellulose content was mainly affected by frost free period, the latitude, the annual average temperature, soil organic matter and available P;while the main influence factor of the fiber length was soil a?vailable K. We could reach our conclusion that as Xuan paper materials, the bark quality from the populations in low lat?itude area was better than that in high latitude area universally.
