【摘要】 采用《中药材产地适宜性分析地理信息系统》(TCMGIS-Ⅰ),以河南柘城县老王集乡柘首乌种植基地为分析基点,选取温度、海拔、土壤、降水量等影响柘首乌生长发育的关键生态因子,对柘首乌在中国的生态适宜性及其道地产区河南省的生态适宜性进行了分析。结果表明,中国柘首乌适宜产区面积很大,9省份均可生长,相似度为90%～100%时柘首乌在全国9个省市的适宜区分布面积理论值可达149 036km2,以山东和河北2省分布范围最大,面积可达到50 000km2以上,其次是河南、辽宁、天津等省。相似度为90%～100%时河南省内柘首乌的适宜区域集中在柘城、林县和安阳等县,与柘首乌道地产区相关资料记载一致。更多还原

【Abstract】 The TCMGIS-Ⅰ(Suitability evaluation geographic information system of traditional Chinese medicine producing area)was used to analyze the ecological suitability of Polygonum multiflorum Thunb in China and the main production area in Henan province starting point on the area of Fangcheng county,Henan province.The key ecological factors such as temperature,altitude,soil type,precipitation which affect the growth of Polygonum multiflorum Thunb were chosen to calculate.The results showed that it could be distributed in 9 provinces in China and the theoretic value of the suitable distributing area was more than 149 036km2 in 9 provinces which their semblable degree was 90%～100%,and the largest distributing area was in Shandong and Hebei provinces,followed by Henan,Liaoning,Tianjin and Shanxi provinces and their area were all above 40 000km2.The suitable area of Polygonum multiflorum Thunb was centralized in Zhecheng,Linzhou and Anyang counties in Henan province,which were coincident with the correlating recorded data of the adaptive production area in history.更多还原
