地理环境因子对黄花蒿中青蒿酸含量空间分布影响的探测分析(1)

     [摘要]道地藥材指经过中医临床长期应用优选出来的,产在特定地域,受到特定生产加工方式影响,较其他地区所产同种药材品质佳、疗效好且质量稳定,具有较高的知名度的药材。道地药材是我国几千年悠久文明史、中医中药发展史形成的特有概念,根据道地药材的定义,可以看出不同地域之间的同种药材在质量和疗效等方面存在一定的差异性,在特定区域还存在一定的相似性。该文基于采样点的青蒿酸含量及其各种潜在的地理环境因子,应用地理探测器模型,分析了地理环境因子对中国各地黄花蒿中青蒿酸含量空间分布的影响。研究发现:青蒿酸含量的空间分布是多种因素综合作用的结果,各环境因子对青蒿酸含量的空间分布的影响依次为土壤类型(0233)>年均辐射量(0208)>植被类型(0192)>高程(0171)>日照(0170)>年均气温(0153)>年均降水量(0111)>坡度(0110)>相对湿度。其中,土壤类型和年均辐射量是探测到的主要影响因素,且主要影响区域在土壤类型为初育土,年均辐射量为1 200~1 400 kWh·m-2的分区。该研究筛选出的地理环境主导因子可用于遥感技术监测青蒿酸的空间分布区域,从而为黄花蒿的种植等提供理论依据。

    [Abstract]Daodi herbs are preferred by longterm clinical application of Chinese medicine, they are produced in a specific area and affected by the specific production and processing methods Daodi herbs have a high reputation, compared with other regions produced by the same kind of herbs with good quality, good efficacy and stable quality characteristics Geoherbal is a unique concept that has been formed by the history of Chinese civilization for thousands of years and the history of Chinese medicine According to the definition of geoherbal, it can be seen that there are some differences in the quality and efficacy of the same kind of medicinal herbs in different regions, and there is some similarity in the specific area In this study, based on the content of artemisinic acid in sampling points and its potential environmental factors, the effects of geographical environment factors on the spatial distribution of artemisinic acid content in Artemisia annua were studied by using the geophysical model The results show that the spatial distribution of artemisinic acid content is the result of a combination of multiple factors The effects of environmental factors on the spatial distribution of artemisinic acid were in the order of soil type (0233)> radiation (0208)> vegetation type (0192)> elevation (0171)> sunshine (0170)> annual mean temperature (0153) >annual precipitation (0111)> slope (0110)> relative humidity Among them, the soil type and the amount of radiation are the main influencing factors, and the main influencing area is in the soil type as the initial soil and the average annual radiation of 1 2001 400 kWh·m-2 The main influencing factors selected in this study can be used to monitor the spatial distribution of artemisinic acid by remote sensing technology, so as to provide the theoretical basis for the cultivation of A annua
