摘要
目的:研究黄芩在河北省燕山及太行山山脉生态适宜性区划。方法:通过第四次全国中药资源普查等方式获取黄芩分布位点信息,利用地理信息系统技术和最大信息熵模型分析其分布区的主导生态因子、数值和权重,得出黄芩药材在河北省的生态适宜生长区。结果:研究表明,海拔、坡度、最暖季降水量、最湿月降水量、年均温、土壤类型、植被类型7项环境因子是影响黄芩分布的主要生态因子;黄芩在河北省的生态适宜生长区主要分布在承德、张家口、保定等地的燕山及太行山山脉区域。结论:可在太行山山脉的承德市、张家口市、保定市,燕山山脉的秦皇岛市引种栽培黄芩。
Objective:To study the ecological suitability regionalization of Scutellaria baicalensis in the Yanshan and Taihang Mountains of Hebei Province,China.Methods:Information on the distribution sites of S.baicalensis was obtained through the Fourth National Survey of Chinese Herbal Resources and other sources.Geographic information system(GIS)technology and the maximum entropy(MaxEnt)model were used to analyze the dominant ecological factors,their values,and weights in the distribution areas,resulting in the identification of ecologically suitable growth zones for S.baicalensis in Hebei Province.Results:The study revealed that altitude,slope,precipitation in the warmest season,precipitation in the wettest month,annual average temperature,soil type,and vegetation type were the primary ecological factors affecting the distribution of S.baicalensis.The ecologically suitable growth zones for S.baicalensis in Hebei Province are primarily located in the Yanshan and Taihang Mountains regions,including Chengde,Zhangjiakou,Baoding,and other areas.Conclusion:S.baicalensis can be introduced and cultivated in cities such as Chengde,Zhangjiakou,and Baoding in the Taihang Mountains,as well as Qinhuangdao in the Yanshan Mountains.
