Abstract:

The research contents of the complex Informatic Tupu of natural landscape in China include the outline partition of natural landscape types, the establishment of TuPu character and index system, Tupu retrieval system, TuPu quantity index system, TuPu mathematical model, Tupu database and demo system of natural landscape, and the application research on TuPu. According to the rules of establishing index system, we divide Chinese natural landscape into 82 natural landscape types. Their attribute index include satellite image character, temperature zone and dry and humid sections, geological and construct traits, topographical gurgitation and relief types, water system construct characters, vegetation types, aprotypes, ground utilization and soil overlay types, direction of utilization and protection. Attribute database structure was designed according to attribute description index. The outlines of complex Informatic Tupu of natural landscape in China base on the borderline of landscape type, then consult 1:500 000 satellite image and recognize 1:10 000 000 land satellite image, lastly conform and draw the outline of landscape type piece by piece.

Key words: natural landscape, complex Informatic TuPu, outline, index system
