全国中药资源普查中位置信息获取和共享应用设计

在浩瀚的文献资料中,多有关于中药材分布信息的论述。受技术方法的限制,历代本草中关于中药材产地或分布方面的资料,多为宏观层面的描述信息。明确区域内中药资源的种类和分布等本底信息,是全国中药资源普查工作的主要目标之一。根据全国中药资源普查技术规范和试点工作经验,普查队借助"3S"技术、计算机网络技术、数码拍照技术等现代技术方法,可有效收集中药资源位置信息。详细、具体的位置信息,为区域间资源禀赋差异和相似性、生物特性和空间分布规律等方面的研究,均提供了数据支撑。在空间信息技术的支持下,基于位置信息,可以实现对多来源普查数据统计汇总和共享应用。进行中药资源及相关基础数据的融合,可对海量数据进行空间化融合、汇总和管理,有助于从总体水平上挖掘中药资源的科学规律,全面揭示其科学内涵。

Location information acquisition and sharing application design in national census of Chinese medicine resources

In literature, there are many information on the distribution of Chinese herbal medicine. Limited by the technical methods, the origin of Chinese herbal medicine or distribution of information in ancient literature were described roughly. It is one of the main objectives of the national census of Chinese medicine resources, which is the background information of the types and distribution of Chinese medicine resources in the region. According to the national Chinese medicine resource census technical specifications and pilot work experience, census team with "3S" technology, computer network technology, digital camera technology and other modern technology methods, can effectively collect the location information of traditional Chinese medicine resources. Detailed and specific location information, such as regional differences in resource endowment and similarity, biological characteristics and spatial distribution, the Chinese medicine resource census data access to the accuracy and objectivity evaluation work, provide technical support and data support. With the support of spatial information technology, based on location information, statistical summary and sharing of multi-source census data can be realized. The integration of traditional Chinese medicine resources and related basic data can be a spatial integration, aggregation and management of massive data, which can help for the scientific rulesdata mining of traditional Chinese medicine resources from the overall level and fully reveal its scientific connotation.
