| Abstract: |
| The ecological landscape information spectrum is one kind of the geoinfo-spectrum.Regarding the research of ecological landscape type in arid areas of Xinjiang, analyzing the change of landscape pattern by using quota research technique of the landscape ecology can not get a direct-viewing and precise expression.Using geo-info-spectrum method to study the dynamic change of landscape essential factors in arid areas, by taking the mode of the graph, and making natural, humanities and ecological factors and any other conditions together to the overall evaluation is helpful to study the change of typical landscape type and to solve the ecological environment problems.The basic data are Landsate TM data in 2000, CBERS-2/CCD data on 2005-06-12, the attribute data and statistic data.They are computed with the software of GIS, to identify mode, to classify landscape and to express the classification.Finally, the change information spectrum of Shanshan oasis landscape essential factor type is established to get the attribute database by using the GIS spatial analysis function.From the point of view of geo-info-spectrum we can analyze the space-time change of arid areas oasis landscape essential factor and make statistics of the value of the landscape factors, which can serve as the reference for the construction of landscape. |
