본 연구의 목적은 쑥속 자원에 대한 생육인자간 상관성 구명과 생육인자 모형 개발을 위해 수행하였다. 생육인자의 특성에서 초장 초폭, 엽병장, 엽록소량은 더위지기, 엽장은 넓은잎외잎쑥, 엽폭은 쑥, 줄기직경은 뺑쑥, 엾두께는 더위지기, 쑥, 산쑥, 넓은 잎외잎쑥, 그늘쑥이 가장 높은 값을 나타냈다. 생육인자 간 상관분석 결과 사철쑥은 엽폭과 줄기직경, 산쑥은 초장과 초폭, 넓은잎외잎쑥은 초장과 엽폭, 나머지 종들은 엽장과 엽폭이 높은 상관성을 보였다. 생육인자 모형 분석 결과 사철쑥은 약 79.4%, 쑥은 약 91.7%, 산쑥은 약 70.3%, 더위지기는 약 49.0%, 넓은잎외잎쑥은 약 72.5%, 그늘쑥은 약 75.0%, 뺑쑥은 약 60.4%, 덤불쑥은 약 54.4%의 설명력을 나타내었다. The purposes of this dissertation were to examine relativity between growth characteristics factors and develop the model of growth characteristics. In the result of statistical summaries of the factors in growth characteristic, the highest level of correlation was in plant height, plant width, petiole and chlorophyll in the case of Artemisia iwayomogi; leaf length, in the case of A. stolonifera;, leaf width, of A. princeps var. orientalis;, diameter, of A. feddei;, leaf thickness, of A. iwayomogi, A. princeps var. orientalis, A. montana, A. stolonifera, A. sylnatica; leaf length and leaf width of the other species. In the case of correlation analysis, leaf width and diameter were most correlative in A. capillaris;, plant height and plant width, in A. montana; plant height and leaf width, in A. stolonifera; leaf length and leaf width, in other species. The results of model analysis of growth characteristics were as follows. A. capillaris proved to be about 79.4% effective ; A. princeps var. orientalis, about 91.7% ; A. montana, about 70.3% ; A. iwayomogi, about 49.0% ; A. stolonifera, about 72.5%; A. sylnatica, about 75.0%;, A. feddei about 60.4% ; A. rubripes about 54.0%.

The altitude was the most in 300~400 m. In direction, NW was the most, and it showed SW in that order. The slope angle was the most in 0~10%, and the cliff showed in that order. In the results of species composition by stratum layer, Berchemia berchemiaefolia had the most, 15 species, in tree layer. In shrub and herb layer, this had the most as 20 species and 29 species, too. The species that occupied the largest size was Salix chaenomeloids in 2,500㎡, and Jeffersonia dubia showed 1,500㎡ in that order. The conservation of specific plants is to accomplish the ex situ and in situ conservation at the same time.
