基于气候因子的白术生态适宜性区划研究

Research on climatic factors of ecology suitability regionalization of atractylodis

通过对白术中白术内酯类成分含量与气候因子之间的相关性研究,对白术在全国主产区5省份的气候适宜性进行区划研究,为开展白术种植的合理区域选取提供科学的依据。在对全国5省份40个产地白术实地采样的基础上,应用统计分析方法,全面分析了不同气候因子条件下白术内酯类成分含量的变异,及各气候因子对白术内酯类成分含量的影响。并应用空间技术,依据白术内酯类成分含量与气候因子之间的关系,进行了基于气候因子的白术生态适宜性区划。最适宜白术内酯类成分积累的气候条件为：最湿月降水量（220~230 mm）、最暖季平均温（25℃以下）、最干季平均温（大于10℃）。

Through study on the correlation between atractylodis lactones ingredient content and climatic factors,we research regionalization from climatic of five main producing provinces of the country,in order to provide a scientific basis for atractylodis＇ conscious cultivation. By sampling from 40 origins which from five main producing provinces of the country,we use SPSS to analysis variation of atractylodis lactones ingredient content in different conditions of climatic factors and the effect of each factors. Then according to the relationship between atractylodis lactones ingredient content and climatic factors,we use Arc GIS to conduct ecological suitability regionalization based on climatic factors. The most suitable climatic condition for cultivation of atractylodis： the wettest month precipitation220-230 mm,the warmest average temperature 25 ℃,the average temperature of driest season 10 ℃.
