摘    要:目的:分析广西气候条件下青蒿中青蒿素含量变化的主要影响因子,以确定青蒿最佳种植区域。方法:测定广西各地青蒿中青蒿素含量和各地环境信息,并进行相关和逐步回归分析,用GIS进行地理空间分析和区划。结果和结论:温度和日照对青蒿素含量的影响最大,降雨量次之,湿度对青蒿素含量的影响较小,风速对青蒿素含量的影响不明显。此外,苗期和花期的气候因子对青蒿素含量的影响最大,其中花期时,日照时相对较短、温度相对较低、降雨量较小的区域内青蒿中青蒿素含量较高。桂东北和桂西南丘陵、山地海拔较高的区域最适宜种植青蒿;而桂中和桂东南平原地区则不适宜种植青蒿;平原向山地的过渡地带亦是青蒿人工种植的适宜区域。

关 键 词:青蒿素  气候因子  等级区划  空间变异

Abstract:Objective: To analyze the major effective factors under the climatic conditions of Guangxi which influence artemisinin content, in order to determine the best planting region. Method: The correlation, the gradually regression analysis with the statistical analysis system, the geography space analysis and the regionalization with GIS were used for the study. Result and conclusion: The temperature and the sunshine-hour were the major effective factors to artemisinin content, followed by the rainfall amount, the humidity showed less influence, and wind speed had no effect; And the climatic factors of seedling stage and the flowering season were the most influences to the artemisinin content. The artemisinin content was higher during the flowering season, in the region of temperature relatively lower and the rainfall amount smaller. The knoll and the mountainous region in northeast and southwest of Guangxi is the best suitable region for the Artemisia annua planting. The plain area in the southeast and middle of Guangxi is the not suitable region; Other areas are suitable regions for the A. annua planting.
Keywords:artemisinin  climatic factors  regionalization  spatial variability
