贵州省江口县木本鞣料植物资源调查及分析

摘要

In order to understand the current situation of germplasm resources of woody tanning plants and to protect and utilize woody tanning plant resourcesin Jiangkou County,Guizhou Province,the woody tanning plant resources in the county were investigated and analyzed systematically.It was found that there are 115 spe-cies of woody tanning plants,belonging to 43 families and 77 genera in Jiangkou County,including 4 dominant families and 3 dominant genera.The families including 2-4 species and single species constitute the majority in this region.The tree type of is the major life type of the woody tanning plant resources in this region,accounting for 53.91% of the total species and the deciduous species in different life types is the dominant type. In the woody tanning plants,those containing tannin in their bark constitute the majority,counting 61.74% of the total species.This pape also puts forward some suggestions for the development and utilization of tanning plant re-sources,providing theoretical support for the development and utilization of these plant resources.%为深入了解贵州省江口县木本鞣料植物种质资源现状,更好地保护与利用该区植物资源,对该区木本鞣料植物资源进行全面系统的调查.得出了该区木本鞣料植物共有43科77属115种,其中有优势科4科,优势属3属,同时以2~4种的科以及单种属占有明显优势.该区木本鞣料植物资源的生活型以乔木类型居多,占总种数的53.91%,各生活型中又以落叶型占主导.在该区木本鞣料植物中,以树皮可提取栲胶的种类居多,占总种数的61.74%.同时提出了一些开发利用该区鞣料植物资源的建议,旨在为这些植物资源的开发利用提供理论支持.
