摘要
系统基于VF语言,应用数据库技术,依据《生态环境状况评价技术规范》,实现对区域生态环境状况评价的规范操作和快捷运算,科学地反映特定区域内各部分横向之间生态环境状况的优劣等级以及同一部分纵向年度之间生态环境状况的动态变化;系统直观的操作方式很大程度地提高了生态环境状况评价的效率,特别是系统对3S软件导出数据的统计功能,有效的促进了3S数据在生态状况评价中的应用。本文概要介绍了系统的组成、结构、数据库以及系统的功能及其实现。
According to criterion on evaluation technology of eco- environment in xinjiang, database technology applied based on VF could realize canonical and fast calculation, which reflected level situation and dynamic change of eco - environment. Evaluation framework, database and system function were introduced in this paper. Evaluation efficiency was improved in very great degree. Statistical function for export data from 3S software promoted application in eco- environment evaluation field.
