ABSTRACT
<p><b>OBJECTIVE</b>To study ecology suitability rank dividing of Polygonum capitatum for selecting artificial planting base and high-quality industrial raw material in Guizhou province.</p><p><b>METHOD</b>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.</p><p><b>RESULT AND CONCLUSION</b>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.</p>
