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.
