[目的
]
黄芩(Scutellaria baicalensisGeorgi)是中国3级野生保护药材物种。利用生境适宜性评价模型对黄芩的适宜生境进行区划
并计算各适宜生境面积
为保护和实现黄芩资源的可持续利用提供科学依据。[方法
]
利用熵权物元模型
建立黄芩标志性药用成分黄芩苷(C

)含量与15个环境评价因子之间的模糊隶属函数
采用熵值法确定各评价因子权重
结合GIS空间分析模拟中国黄芩生境适宜区地理空间分布。[结果
]
中国黄芩不适宜生境、低适宜生境、中适宜生境和高适宜生境的面积分别为5.07×10

其中高适宜生境主要集中在秦岭-淮河一线以北
以河南、山东、辽宁、陕西中南部、河北、吉林、黑龙江南部、山西南部等地区为显著代表
此外云南、安徽等省也有少量分布
与实际分布范围极为吻合。[结论
]
评价因子中平均日较差、降水季节性变化、最湿月降水量以及坡向基本控制了黄芩的地理空间分布。
[Objective] Scutellaria baicalensisGeorgi is the third-class conservation of wild medicinal species. We used habitat suitability assessment model to divide the suitable habitat because this information could provide scientifical support for the conservation and sustainable utilization of resources.[Methods] Entropy weight and matter element model were used to determine the fuzzy membership function of baicalin content and 15 assessment factors. The entropy evaluation method was used to determine the weight of each factor. Finally
we estimated the spatial distribution ofS. Baicalensisby GIS spatial analysis in China.[Results] The area of unsuitable
less-suitable
moderately-suitable and high-suitable habitat for S. baicalensis was 5.07×106
1.65×106
1.88×106 and 1.00×106 km2
respectively. The high-suitable habitat are mainly located in the north of Qinling Mountains-Huaihe River line
significantly Henan
Shandong
Liaoning
central and southern of Shaanxi
Hebei
Jilin
southern of Heilongjiang and Shanxi. In addition
there were some distribution in Yunnan
Anhui Province and other places
which was highly consistent with the actual distribution range.[Conclusion] Among all selected factors
mean diurnal range(MDR)
precipitation seasonality(PS)
precipitation of wettest month(PMAX) and aspect(ASPE) are the main control factors.
