摘要
目的:分析我国道地药材产地地理特征,筛选中药材地理标志分布的主要影响因素。方法:运用核密度分析、皮尔森相关系数、多元线性回归分析方法,定量研究中药材地理标志空间分布特征及其影响因素。结果:中药材地理标志在我国国土空间内形成了东部多于西部、南方多于北方的分布格局,地形阶梯分界线、气候交汇区域是主要聚集区。中药材地理标志核密度热点区集中连片,覆盖了大部分脱贫攻坚重点区域,基本涵盖了药用植物种质资源的点状核密度热点区。核密度热点区大多处于山区,海拔与地势较高,光照、温度、水分等自然条件较好的区域,与药用植物的生长习性相符。药用植物种质资源数量、地理标志总量、平均海拔是影响空间分布的主要因素,年均降水量、年日照时数、林业用地面积、人均GDP、运输线路总长度与中药材地理标志空间分布特征存在显著的相关性。结论:中药材地理标志空间分布具有一定规律,分布特征的形成主要受自然环境因素影响,因此,道地药材的主产地在申报地理标志时具有先天优势。
Objective:To analyze the geographical characteristics of the origin area of famous-region drugs in China,to screen the main influencing factors of the geographical indication distribution of traditional Chinese medicinal materials.Methods:Kernel density analysis,Pearson correlation coefficient and multiple linear regression analysis were used to quantitatively study the spatial distribution characteristics and influencing factors of geographical indications of traditional Chinese medicinal materials.Results:The geographical indications of traditional Chinese medicinal materials formed a distribution pattern of more east than west and more south than north in China′s territorial space,the topographic ladder boundary and climate intersection area were the main gathering areas.The hotspots of nuclear density of traditional Chinese medicinal materials were concentrated and contiguous,covering most of the key areas of poverty alleviation,and basically covering the hotspots of dot nuclear density of germplasm resources of medicinal plants.The hotspots of nuclear density were mostly located in mountainous areas with high altitude and terrain,and good natural conditions such as light,temperature,moisture,which were consistent with the growth habits of medicinal plants.The quantity of germplasm resources of medicinal plants,total amount of geographical indications and average altitude of medicinal plants were the main factors affecting the spatial distribution,and there were significant correlations between the spatial distribution characteristics of geographical indications of traditional Chinese medicinal materials and average annual precipitation,annual sunshine hours,forestry land area,per capita GDP and total length of transportation lines.Conclusion:The spatial distribution of geographical indications of traditional Chinese medicinal materials has certain rules,the formation of distribution characteristics is mainly affected by natural environmental factors.Therefore,the application of geographical indications of genuine medicinal materials has innate advantages.
