【摘要】：本文以“数字地球”理论为出发点,结合生态环境科学的具体研究方法,创建了农业生态环境系统的信息模型,并在此基础上进行了数字信息系统的总体设计,将数字信息系统的开发建立在各信息模块建设的基础上,最后通过系统集成方案,将各信息模块及其功能纳入到了统一的工程体系中,建立了吉林西部农业生态环境数字信息系统,并完成了农业资源可持续利用综合研究的应用实例。该数字信息系统以空间数据管理和环境模拟分析为核心功能,解决了传统生态环境研究中普遍存在的信息容量少、数据共享困难、可视化和自动化程度较低等问题,可为吉林西部的农业生态环境的评价、预测、仿真优化等连续的系列性研究提供空间数据、指标体系、环境模拟模型及一体化操作平台。
[Abstract]:Based on the theory of "digital earth" and the specific research methods of ecological environment science, this paper establishes the information model of agricultural ecological environment system, and on the basis of this, carries on the overall design of digital information system. The development of digital information system is based on the construction of each information module. Finally, through the system integration scheme, the information modules and their functions are brought into the unified engineering system. A digital information system for agricultural ecological environment in western Jilin Province is established, and an application example of comprehensive study on sustainable utilization of agricultural resources is completed. The digital information system takes spatial data management and environmental simulation analysis as the core functions. It solves the problems of low information capacity, difficult data sharing, low degree of visualization and automation in traditional ecological environment research, which can be used for the evaluation and prediction of agricultural ecological environment in western Jilin Province. Continuous series of research, such as simulation optimization, provide spatial data, index system, environmental simulation model and integrated operation platform.
