基于GIS的县级生态公益林管理系统的设计与开发

Design and development of GIS-based county-level ecological public forest management system

针对县级林业信息化中的生态公益林管理,设计开发了一个基于地理信息系统(GIS)的生态公益林管理系统。系统主要包括生态公益林管理、统计分析和结构分析等功能,并实现了空间数据和属性数据的集成管理与关联。在数据组织上,提出以县,乡(镇、林场),村,小班为多级单位组织数据,可避免由于采用图幅管理方式所带来的大量地物(如县、乡、村边界和小班等)被图幅线人为分割开的现象,也避免图幅分割所带来的处理过程复杂和小班的完整性被破坏的缺陷。在系统的功能结构方面,根据现行生态公益林管理的实际情况,将生态公益林管理系统划分为数据管理、专题图管理、结构分析、报表统计和图形输出等5大模块。

A GIS-based ecological public forest management system was designed to conduct the management of the ecological public forest at the county level. The functions of the system included the management, statistic analysis and structure analysis of the ecological public forest. The system realized the integrated management and connection of spatial data and attribute data. Taking the county, townships (towns, forestry centers), villages and teams as multi-level units to organize data could avoid the complex processing procedures and spoiled integrity of small teams as well as the artificial segmentation caused by the map management. The ecological public forest management system could be divided into five modules according to its functional structure: data management, special maps management, structure analysis, form statistic and map print
