【摘要】 Under natural conditions,a total of 36 growth sites for Artemisiae annie L. in Three Gorges Reservoir Region were selected. Factors affecting the artemisinin content in A. annie leaves were researched by principal component analysis. Results showed that the accumulative contribution rate of the first three principal components was 89. 258 6%,which represented the whole information of relevant factors of artemisinin content. Principal component 1 was the sunlight and soil factor of A. annie,principal component 2 was the three-dimensional climate factor,and principal component 3 was the biomass factor. The 36 growth sites of A. annie were classified into four categories. According to the planting needs of artemisinin,the most suitable planting sites for sunlight and soil factor and three-dimensional climate factor were Youyang County and Xiushan County,which were consistent with the actual harvesting sites of raw materials in Three Gorges Reservoir Region.
