Study And Application Of Geo-information TuPu

This paper first introduces that geo-information Tupu is a sort of digital map,chart,curve or image that can reflect the rule of geography interspace information,which is arranged according to a certain law of guideline change or classification system.It is the consequence of the interspace age and information society.It reveals the advancement during a phase and the interface differentiation of nature and sustainable development of the society economy in a region.It can reappear the history and simulate the future,which is a scientific method and new technical measure to study the element and the society development in a region.The differentiate and relation of map and Tupu,geography Tupu and common Tupu, geography Tupu and geo-information Tupu are compared in this paper. The landuse dynamic changing information Tupu of Fuzhou city during the 11 years and the model of the relation between landuse and population and society economy are set up basing on RS and GIS.At last,the characteristics of biology landscape in Fuzhou are validated through Fuzhou ecological environment comprehensive informatic Tupu.When the landuse dynamic changing information Tupu of Fuzhou city is setting up,the directly comparing method of several times spectrum data and thresholding are used to pick up the changing information from the two TM images automaticly.And the interspace and corresponding attribute database are set up under the people-computer mutual unscrambling.And then the information Tupu is set up by the spacial analyse function of GIS,including land use distribution information Tupu,change of land use information Tupu, information Tupu of gradual process of landuse, change information of construction land, and also the transformation of land use area.The analyse of Tupu shows that during the 11 years,the area of plough and woodland is decreasing,while the one of construction land and garden in Fuzhou is increasing because of the development of the city.Furthermore,there's obvious interspace difference within the landuse changing,and it's closely correlative with the nature and society economy.In the application research of Tupu pedigree,the result of the ecological environment comprehensive informatic tupu of Fujian province is used to approve the application in...
