基于最大熵模型的我国黄芩生态适宜性研究OACSTPCD
Study on Ecological Suitability of Scutellaria baicalensis Georgi in China Based on MaxEnt Model
目的 了解黄芩的生态适宜性,筛选影响其分布的主要生态因子,预测黄芩在我国的适宜栽培区.方法 通过第四次全国中药资源普查收集黄芩药材231批次,记录采样点环境信息,应用最大熵模型和地理信息系统进行55个生态因子的综合分析.结果 降水量、植被类型及土壤类型对黄芩生长影响较大,黄芩适宜区主要集中在陕西东部、河北西部及承德大部、山西大部、北京西部、辽宁西部、山东中部与东部、江苏与安徽交界处、云南北部、四川东部与南部.结论 本研究对黄芩生态适宜区进行划分,研究结果可为黄芩栽培区域的选择提供参考依据.
Objective To understand the distribution of ecological suitability of Scutellaria baicalensis Georgi;To screen the main ecological factors affecting its distribution;To predict its suitable planting area in China.Methods A total of 231 batches of Scutellaria baicalensis Georgi were collected through the fourth national survey of TCM resources.The environment information of sampling points were recorded,and 55 ecological factors were analyzed by MaxEnt model and GIS.Results Rainfall,vegetation type and soil types had a greater influence on the distribution of Scutellaria baicalensis Georgi.The ecological suitable areas of Scutellaria baicalensis Georgi mainly concentrated in the eastern part of Shaanxi Province,the western part of Hebei Province and most areas of Chengde,the most part of Shanxi Province,the western part of Beijing,the western part of Liaoning Province,the central and eastern part of Shandong Province,the junction of Jiangsu and Anhui Province,the northern part of Yunnan Province,and the eastern and southern part of Sichuan Province.Conclusion The ecological suitability areas of Scutellaria baicalensis Georgi were classified in this study,and the results could provide reference for the selection of cultivation areas of Scutellaria baicalensis Georgi.
