目的:通过分析西洋参在中国的适宜生长区域,为确定西洋参种植产区以及合理规划生产布局提供科学依据。方法:以西洋参原产地美国威斯康星州为分析的基点,选取1月平均气温、7月平均气温、海拔、土壤、降水量等影响西洋参生长发育的关键生态因子,采用《中药材产地适宜性分析地理信息系统》(TCMGIS-Ⅰ)对西洋参在中国的生态适宜性进行分析。结果:中国的西洋参适宜生长的区域集中在东北和华北地区,陕西省也有部分的适宜地区、但面积较小。系统分析的结果与西洋参长期引种后逐步形成的区域有很大的符合度。结论:中国西洋参发展应主要以华北和东北为中心。TCMGIS-Ⅰ系统用于中药材引种及生产区划具有重要的价值。
OBJECTIVE: To provide a scientific basis for determining the planting area of American ginseng and the rational planning and production layout by analyzing the suitable growth area of American ginseng in China. Methods: Based on the analysis of Wisconsin origin in American ginseng, the key ecological factors affecting the growth and development of American ginseng were selected as the mean temperature in January, the average temperature in July, altitude, soil and precipitation. Information System "(TCMGIS-Ⅰ) to analyze the ecological suitability of American ginseng in China. Results: The suitable growing areas for Chinese ginseng are concentrated in the northeast and north China, and some suitable areas in Shaanxi Province, but the area is small. The results of the systematic analysis are in good agreement with the areas gradually formed after long-term introduction of American ginseng. Conclusion: The development of Panax quinquefolius in China should mainly focus on North China and Northeast China.
