面向森林经营单位的小班数据共享技术研究

Software Implementation and Validation of Subcompartment Data Sharing Techniques at Level of Forest Management Unit

以广东省河源市某林业公司为例,研究了面向森林经营单位的小班数据共享技术,实现了基于Visual Basic开发环境的软件平台。该软件平台可对小班数据执行规范化处理、地籍号编码、数据提取、数据更新等实用操作,实现森林经营单位与广东省森林资源数据库的小班数据共享。

Based on a forest corporation of Heyuan, a primary forest management unit （ FMU）, a case study of data sharing techniques and software implementation was conducted. The results showed that, the software platform on Microsoft Visual Basic can be employed to normalize data items, to encode such data items as from administrative units as county, town, village to compartment, subcompartment and sub-subcom- partment, to subtract sub-datasets from datasets of Guangdong forest resources center and to update subcompartment datasets managed by pri- mary FMU, and thus it realizes data sharing between primary FMUs and Guangdong forest resources center for forest management inventory （FMI） data.
