Abstract: 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, fiber 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 available K. We could reach our conclusion that as Xuan paper materials, the bark quality from the populations in low latitude area was better than that in high latitude area universally.
