[Research on climatic factors of ecology suitability regionalization of atractylodis].

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 ArcGIS to conduct ecological suitability regionalization based on climatic factors. The most suitable climatic condition for cultivation of atractylodis: the wettest month precipitation 220-230 mm, the warmest average temperature 25 degrees C, the average temperature of driest season 10 degrees C.

[Research on topographic factors of ecology suitability regionalization of Atractylodis macrocephala].

Through study on the correlation between Atractylodis macrocephala lactones ingredient content and topographic factors, we researched regionalization from topography of five main producing provinces of the country, in order to provide a scientific basis for A. macrocephala reasonable cultivation. By sampling from 40 origins of five main producing provinces of the country, the variation of A. macrocephala lactones ingredient content in different conditions of topographic factors and the effect of altitude, slope and aspect was analyzed by SPSS. Then according to the relationship between A. macrocephala lactones ingredient content and topographic factors, the ecological suitability regionalization was conducted by using ArcGIS based on topographic factors. It is suitable for growth of A. macrocephala in the hilly and mountainous areas of southern whose A. macrocephala lactones ingredient content is in high levels. It is unsuitable for growth of A. macrocephala in Northern plain areas, but we can cultivate A. macrocephala in the hilly and mountainous areas of Northern. The most suitable topographic condition for cultivation of A. macrocephala : altitude 200 meters above, slope 3.00-4.99 degrees.
