铁路工程建设节约用地咨询系统的研究

＂铁路工程建设节约用地咨询系统＂是＂工程建设用地辅助决策系统＂的一个子系统，根据行业的不同分为铁路、公路、火力发电厂、工矿企业生活小区等独立模块。本文就铁路行业的工程建设节约用地咨询系统模块从系统的开发背景、总体结构、技术要点、使用特点及说明几方面作一详细阐述。系统以ＦｏｘＰｒｏ２．５ｆｏｒＷｉｎｄｏｗｓ为开发平台，继承并发扬了Ｗｉｎｄｏｗｓ环境的多窗口性、图文并茂等特点，把众多的建设方案、措施、行业知识以数据库的形式统一管理，具有很强的科学性、针对性，从而使迅速地解决实际问题成为可能

Research on Land Economizing Inquiry System in Railway Engineering Construction

The Land Economizing Inquiry System in Engineering Construction, which is divided into several separate models by different occupations: railway, highway,power plant, resident blocks, and so on, is a sub - system of Assistant Decision System on Engineering Construction Land-using. The article presents a detailed system explanation, including the system developing background, the whole structure of the system,the technical points of the system and program, the characters of the system usage and some directions. The system is developed on the platform of FoxPro 2. 5 for Windows.It carries on the outstanding characters of the windows environment, such as maltiple windows, pictures and illustrates being in perfect harmory. The system scientifically administrates a great deal of construction schemes, measures and knowledges in form of databases, making it possible to solve the pratical problems promptly.
