摘要(Abstract):

目的:通过对头花蓼中没食子酸与地形因子之间的相关性研究,进行贵州省头花蓼种植的地形适宜性等级划分,为贵州省头花蓼种植最佳区域的选取提供科学依据。方法:在对贵州14个县野生头花蓼资源调查的基础上,应用统计分析方法,全面分析了头花蓼中没食子酸含量地理变异,不同地形条件下没食子酸含量变异,坡度、坡位、坡向、海拔高度等地形因子对没食子酸含量的影响。并应用空间信息技术,依据头花蓼中没食子酸与地形因子之间的关系,进行了基于地形因子的头花蓼生态适宜性等级划分。结果与结论:坡度、坡向、海拔高度对头花蓼中没食子酸含量影响较大。贵州省海拔较低、阴坡、坡度较小的地区,头花蓼中没食子酸含量较高。贵州东部地区头花蓼中没食子酸含量较高,西部地区相对较低。贵州省中东部地区的地形条件最适宜头花蓼中没食子酸含量积累。
Objective: To study ecology suitability rank dividing of Polygonum capitatum for selecting artificial planting base and high-quality industrial raw material in Guizhou province.Method: Based on the investigation of PCB and DEM data of Guizhou province,the relationship between the gallic acid content in P.capitatum and topographical conditions was analyzed by statistical analysis.The geographic information systems(GIS)-based assessment and landscape ecological principles were applied to assess ecology suitability areas of P.capitatum in Guizhou.Result and Conclusion: slope,aspect and altitude are main topographical factors that affect the content of gallic acid in P.capitatum.The gallic acid content of P.capitatum is higher in the lower altitude,shady slope and smaller slope areas.The gallic acid content is higher in the eastern areas of Guizhou province.
