摘要
调查了冬凌草主产区太行山区冬凌草的立地因子,对冬凌草的分布、生长的自然条件、生物学特性及其伴生植物种类进行了介绍。采用《中药材产地适宜性分析地理信息系统》（TCMGIS-Ⅰ）,以河南济源王屋山为分析基点,选取温度、海拔、土壤、降水量等影响冬凌草生长发育的关键生态因子,对冬凌草在中国的生态适宜性以及主产区河南省的生态适宜性进行了分析。结果表明,冬凌草在我国16个省份都可以分布,相似度为90%～100%时冬凌草在全国8个省市的适宜区分布面积理论值可达56 002.7 km2,以山西和河南省分布范围最大,面积均达到13 000 km2以上,而在河南省相似度为90%～100%时冬凌草的适宜区域集中在沿太行山、王屋山走向分布,这和历代冬凌草主产地的相关资料记载以及实际调查结果是相吻合的。
The site factors of Rabdosia rubescens in Taihang Mountain Area（main producing area of Rabdosia rubescens） were investigated.The distribution,natural conditions and biological characteristics of R.rubescens and the species of its accompanying plants were introduced.According to Suitability Evaluation Geographic Information System of Traditional Chinese Medicine Producing Area（TCMGIS-Ⅰ）,with Wangwu Mountain in Jiyuan City of Henan as the basic analysis point, the key ecological factors such as temperature,altitude,soil,precipitation which affected the growth of R.rubescens were chosen to analyze the ecological suitability of R.rubescens in China and its main producing area Henan.The results showed that R.rubescens could distribute in 16 provinces of China.When the similarity degree was 90%-100%,the theoretical distribution area of the suitable area of R.rubescens in 8 provinces（cities） could reach 56 002.7 km2.The distribution range of Shanxi and Henan was the maximum and the area both reached more than 13 000 km2.When the similarity degree in Henan Province was 90%-100%,the suitable areas of R.rubescens were concentrated in Taihang and Wangwu Mountain Areas of Henan Province.The results were accordant with the related records of the main producing areas of R.rubescens in the past years and the actual investigation results.
