分析了目前森林资源各类数据存在的问题。针对问题,从森林经理科学数据整合范畴、森林经理科学数据分类与编码、森林经理科学元数据存储与采集等方面进行研究。研建了森林经理科学数据分类体系和编码方法;设计了相应的数据库、元数据字典和代码库;采用VBA技术开发了元数据采集工具。以热带林业实验中心森林经理科学数据管理应用为案例,初步实现了森林经理科学数据整合方法的探索性研究。应用结果表明:通过科学数据整合能有效地改进数据的质量,使分散在各部分的数据便于规范管理、便于开展多目标、多学科和多行业应用,为以后进一步数据挖掘奠定了基础。

The article reviews the existing problems of forest resource data.According to these problems,the research has been taken in light of the domain,classification and coding,collection and storage about scientific data of forest management:(1)initiating a framework for integrating the forest management scientific data that includes data domain,data property,data acquisition,which aims to deal with the problem by suggesting the use of layer methodology to define the scientific forest management data with different classification standards;(2)identifying data dimensions in the field of forest management,proposing a classification hierarchy of scientific forest management data and specifying the data acquisition card between data property and integration keys;(3)designing a database for integrating forest heterogeneous data and development of meta data collection tools using VBA Technology.The results show that the scientific data integration can improve the data quality effectively,make thedata scattered in various parts easy for management and develop a multi-object,multi-discipline and multi-business application,which provides a basis for forest management data mining in the future.
