县级林业资源管理信息系统的结构研究与应用

Structure study and application of forestry resources management information system at county level

目前县级林业信息化滞后和林业资源信息管理类软件十分缺乏,县级林业资源管理信息系统建设是今后一个时期内林业信息化的重点与难点。以县级林业资源为对象,对县级林业资源信息管理现状进行了充分调研,从县级林业资源管理特点和信息系统原理构架系统体系结构,基于应用需求和系统结构提炼系统功能,提出了县级林业资源信息系统建设的目标,创立了系统5层体系结构———基础数据层、公共平台层、专题数据层、功能组件和功能模块层以及应用系统层。充分考虑3S(GIS,GPS,RS)技术、数据融合与挖掘技术在县级林业资源信息管理中的作用和潜力,合理运用组件技术、数据库技术、集成技术等多种技术开发软件系统,实现了开放性与安全性、灵活性与通用性的统一。重点阐述县级林业资源管理信息系统建设的目标、基本原理、特点、结构以及功能,并简述了在临安市的实际应用。

The backward forestry informationization and the lack of software of forestry resource information management at the county level indicate that the construction of forestry resources management information systems at the county level is a difficult and important task for the forestry informationization. The actualities of forestry resources management information at the county level were investigated and the targets of constructing county-level forestry resources information system were put forward based on the application requirement and system structure. A system with five layers was created. It included basic data layer, common platform layer, subject data layer,function components and modules layer and application system layer. The roles and potentials of 3S （GIS, GPS,RS） technology and technology of integrating and detecting data were taken into full account. The reasonable application of components technology, database technology and integration technology in the development software system realized the unification of openness and safety, agility and universality. The targets, basic principles,characteristics, structure and functions of the forestry resources management information system at the county level were expatiated and the practical application of it in Lin＇an City was briefly introduced.
