区域资源生态系统数字化管理研究

DIGITIZING MANAGEMENT OF RESOURCES ECOSYSTEM

信息化技术已推动生态系统管理进入了数字化管理的时代。将记录资源生态系统要素的信息转化为按一定准则且规范排列的数字信息 ,就形成数字资源生态系统。文中以宁津县数字农业系统为例论述了数字化系统对资源生态研究的主要贡献表现在 :①建立了不同资源层面的空间相关。②构造了反映同一资源层面动态变化模式。③通过基于样本信息的空间插值实现资源生态信息的扩展。④资源生态特征的可视化。数字化资源生态系统的建立给科研人员和管理人员提供了对生态经济进行定量分析的科学手段 ,实现了对复杂的不同空间层面、不同特征类型生态资源的综合分析。

Pushed by information technology, ecosystem management has come into a new stage——digitizing management. To build database of digital resources ecosystem, the information about regional resources ecosystem should be converted into digital information according to certain rules and be arranged normatively. By the case study of digital agricultural system in Ningjin county, main contributions of digitizing system to resources ecosystem can be concluded: 1)the spatial correlation of different resources layers; 2)the dynamic variable model reflecting same resources layer; 3)the spatial extension of resources ecological information by spatial information insertion with sample information; 4)the visualization of ecological characters of resources. Accordingly, the establishment of digitizing resources ecosystem provides scientific methods on quantitative analysis for researchers and managers, and make it possible to synthesis analysis of ecological resources with complex spatial layers and different features.
