Abstract: This research takes Camptotheca acuminate which is grade two of national key protective plant and Taxus chinensis var.mairei which is grade one of national protective plant two plants as objective species and manually collocates the upright structure of aboveground and underground of C. acuminate, T. chinensis var.mairei and Catharanthus roseus,establishes compound. To study the dynamic characters of the growth of the C. acuminate artificial compound community and solid area, the dynamic characters of the meteorological factors and the relationships of them. This study results indicate that in one growth reason the dynamic tendency of the growth of the compound community and solid area is similar,but the difference of the plant height, the basal diameter and the growth rate of the compound community and solid area is obvious.The soil humidity is favorable to the the plant height of C. acuminate and the month cumulation of net radiation is favorable to the basal diameter of C. acuminate of the compound community and solid area; The relationship between plant height of T. chinensis var. mairei of the compound community and month cumulation of rainfall is positive, yet it is positive relation with the net radiation in solid area;The month temperature of soil is favorable to the plant height and the basal diameter of C. roseus of the compound community and solid area.In base of the relationships between the growth characters and the meteorological factors characters, and so we can actualize directional artificial cultivation in the progress of cultivation and provide academic guidances of the excellent cultivation of the compound community of three officinal plant.

Key words: Camptotheca acuminate, artificial compound community, growth, meteorological factors
