摘要
目的:分析石柱参在中国的适生区域,为人工种植适宜区筛选提供科学依据。方法:以辽宁省宽甸县石柱参分布区最适宜生长环境因子为依据,利用中药材产地适宜性分析地理信息系统(TCMGIS),区划石柱参在全国的适宜产地。结果:相似度为95%～100%的适宜面积15943.93km^2,辽宁占96.44%,吉林占3.56%;相似度为90%～95%的适宜面积20070.83 km^3,主要分布在辽宁,占73.88%,吉林和秦岭中东部地区也有一定份额。结论:研究结果覆盖了石柱参现代分布区,预测了石柱参潜在适宜分布区;验证了TCMGIS系统应用于石柱参适生地分析的科学性和准确性;对于规划人参种植区域,保护优良品种,把人参生产规划在真正的适宜产地区域具有重要的参考意义。
Adaptability of Chinese Shizhu panax＇s and associated growing areas were analyzed using TCMGIS to provide scientific evidences for screening potential areas suitable for growing Chinese Shizhu panax. In the study, a geographic information system was established to analyze the adaptability of potential areas suitable for growing Chinese Shizhu panax, based on the optimum ecological data collected from Kuandian County, Liaoning Province. Study results showed that 15 of the areas under investigation enjoy a similarity index of 95%-100%, 15943.93km^2 in area, mainly located in Liaoning Province and Jilin Province, which accounted for 96.44% and 3.56% respectively. There are 22 districts having a similarity index of 90-95%, 20070.83 km^2 in area, mainly located in Liaoning Province, Henan Province, Shanxi Province, and Jilin Province, enjoying a respective portion at 73.88%, 16.02%, 9.78%, and 3.20%. The results went along with the current growing areas and the potential growing regions that have been identified by TCMGIS, suggesting the rationality and reliability of the system. The finding provides important evidences for the P. ginseng cultivation planning, protecting fine varieties, and growing the species under national standards.
