全国道地药材地理标志时空分布及其影响因素

运用ArcGIS软件核密度和缓冲区分析功能,分析道地药材地理标志时空间分布特征及其影响因素。结果表明:(1)我国南方地区是道地药材地理标志的核密度高值区,华中、西南地区山地地形区数据点集聚明显。(2)近20年来,道地药材地理标志增长速度总体较快,增长中心区形态经历了U型、块状、集中连片、点状的变化。(3)影响因素中,地形地貌、河流对道地药材地理标志空间分布形态起决定性作用,政策因素影响较大,交通、经济实力的影响不显著。在掌握现有道地药材地理标志底数与分布状况的基础上,提出“保质量,稳增长”、“树品牌,扩影响”、“重宣传,多推广”的可持续发展建议。

Spatial and Temporal Distribution of Geographical Indications of Genuine Chinese Medicinal Materials and its Influencing Factors

ArcGIS software core density and buffer analysis function were used to analyze the spatial distribution characteristics and influencing factors of geographical indications of genuine medicinal materials.The results show that:(1)south China is the core density high value area of the geographical indications of genuine medicinal materials,and the data points in the mountainous terrain area of central China and southwest China are clustered obviously.(2)In the past 20 years,the growth rate of geographical indications of genuine medicinal materials has been relatively fast on the whole,and the morphology of the growth center has undergone u-shaped,block-shaped,centralized and connected,and point-shaped changes.(3)Among the influencing factors,topographical landforms and rivers play a decisive role in the spatial distribution form of geographical indications of genuine medicinal materials,while policy factors have a great influence,while traffic and economic strength have no significant influence.On the basis of grasping the base number and distribution of the existing geographical indications of genuine medicinal materials,the sustainable development suggestions of"ensuring quality,stabilizing growth","planting brand,expanding influence"and"emphasizing publicity and promoting more"were put forward.
