环境污染区域国土资源信息查询系统设计研究

Design of Land Resources Information Query System for Environmental Pollution Area

传统系统存在查询速度慢、CPU利用率低、耗费时间长、性能差等问题,为此,对环境污染区域国土资源信息查询系统进行设计。建立信息查询系统框架结构,分析图形信息采集和属性信息采集,设计属性数据库结构;针对系统软件部分,设计图形数据采集,构建查询文件,查询系统页面显示,由此实现国土资源信息的查询。通过实验对该查询系统设计的性能进行测试,并得出实验结论。实验结果表明,该系统具有资源信息查询速度快,CPU利用率高,实用性强等优势,为中国国土资源信息查询带来便利。

'The traditional system has problems such as slow query speed,low CPU utilization,long time consuming and poor performance. To solve these problems,this paper designs the information query system for the land and resources of environmental pollution. The frame structure of information query system is established to analyze the information collection and attribute information collection of graphic information,and design the database structure of property. For the software part of the system,the design of the graph data collection,the construction of the query file,the query system page display,the realization of the land resource information query. The performance of this query system was tested by experiment and the experimental results were obtained. The experimental results show that the system has the advantages of high speed,high CPU utilization and high practicability,which facilitate the information query of China's land resources.
