Abstract
Climatic ecoconditions were analysed ofPanax quinquefolium (P.q.) growing indigenously and as introductions. Four climatic indices, namely annual precipitation, annual mean relative humidity, and mean monthly temperature in July and January, respectively were selected as the judge index for introducing P.q. Through applying the methods of grey gather and grey relative analysis in grey system theory, the four climatic indices of 43 counties for typical classification in the Qinba Mountain Regions (QMR), and climatic similarity was calculated of about 43 counties with that of the state of Wisconsin, USA. According to the results and conditions of topography, geomorphology, vegetation, soil etc. in the QMR, a map was drawn of climatic regions suitable for introducing P.q., and the climatic features of each region are discussed.
