电子计算机风景景观信息系统的建立

Creation of Landscape Information System

本研究在国内首次建立了风景景观信息系统。其基础性工作是基于国家级风景名胜区层次的风景景观信息系统方法及其数据库结构的探讨。系统数据源于地球资源卫星专题测图计算机兼容磁带图像数据,航空摄影照片,地图,现场踏勘和统计资料。该系统是用于执行各类风景景观时空数据输入和编辑,存贮和管理,分析和处理,显示和制图的高技术系统。其特点是通过自然景观要素和人文景观要素的景观信息载体,将人类赖以生存的领域场所环境分解转换为一系列可为电脑运算分析及识别判断的符号,进而使有关风景环境——感受信息从集取、转译、评价、规划到提供各类风景工程必需的常规资料图纸电子计算机一体化。

The focus of this study is the creation of a landscape information system which is first done in China. The basis of the work is the method of landscape information system and constructive data-base on the national scenic landscape and spot area level. The resources of the data-base were extracted from Landsat TM CCT images, aerial photos, maps, site investigation and statistical data. This system is a high-tech system in which landscape time-space data could be inputted, edited, stored, managed, analysed, processed, displayed and mapped. The feature of this system is through information carrier of both natural and human landscape elements, that is landscape objects and landscape aesthetics, to analyse and transform environmental places on which human existence depends, into a series of symbols that can be discriminated, analysed and calculated by computers, so as to make landscape information computerized from collecting, translating, evaluating, planning to the supply of routine data necessary in various kinds of landscape engineering.
