摘要
地理信息系统(GIS)是一个收集、储存、分析和传播地球上关于某一地区信息的系统。一个完整的GIS必须具备输入、存贮、操作和分析、表达输出四大功能。GIS以其强大的地理信息空间分析功能,在环境及景观规划项目中发挥着越来越重要的作用,它的发展与某些领域尤其是环境规划设计领域的实践是相互促进的。作为一个强大、灵活的决策系统,它不仅见于大范围的城市及地区规划,自然资源保护及管理,而且国外许多与城市景观设计相关的行业也正在接受这一技术。但它也存在着一些不足,目前GIS的分析与展示诸如噪声、能量平衡、城市气候等环境因子方面的能力,还是有限的。
Geographic Information System is a system that can do data capture, storage, analysis, and display for certain area on the earth. So a complete GIS must possess four functions mentioned above essentially. GIS is playing more and more important role in the projects of environment and landscape planning because of its powerful function in spacial analysis of Geo-Information. As a powerful and flexible technology for decision-making, it is not only employed by the planning and management for environment and natural resources, but also adopted by many fields that are related to urban landscape design. But certain projects still can identified some shortcomings of GIS, it also lacks capabilities for analyzing and displaying qualitative aspects of the environment such as noise, energy balance, urban climate, etc.
