Abstract: In this paper, the author investigated the environments of climatological ecology suitable to the planting and growth of Panax ginseng and the effects of topographical micro-climates of various landforms, and then proposed the local topographical conditions suitable to the cultivation of Panax ginseng in the mountain regions in eastern Liaoning Province. For suitable soil conditions, favourable to the growing of Panax ginseng, and the low lands on the slopes in the valleys of the main tributaries of the Heilungjiang is suggested. River or on the banks of reservoirs, small U-shaped lands on valley slopes and V-shaped lands on valley slopes were selected, the middle-high parts of northern and eastern slopes and high lands about 500 metres height above sea level were used. High yields can be obtained from Panax ginseng grown in the above places.
