Abstract: In this paper, the climatic-ecological factors and their optimum indices having an effect on Panax ginseng yield are studied. The factors are annual mean temperature, annual mean rainfall, the mean temperature of the hotest month, annual mean air relative humidity, and the length of the frostless season. Their optimum indices are 2.6℃, 778.7mm, 19.6℃, 70.6%, and equal to or more than 145 days respectively. The dependent functions [μ(xi)] of the factors to the optimum indices are decided, and the regression model to describe the geographic distribution of the integrated climatic-ecological suitability is established. The geographicdistribution of the μ of various parts of the Changbai mountions area and the optimum culture elevation of Panax ginseng are analyzed according to the model and the geographic network method. And then five climatic-ecological area for the Panax ginseng culture are demarcated in the Changbai mountains area of eastern Jilin Province. They are the optimum area, the suitable area, the comparatively suitable area, the comparatively unsuitable area and the unsuitable area.

Key words: Panax ginseng, cultural suitability, the Changbai mountains area
