Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) images in 1988 and 2002 were used to
quantify the land use and land cover changes (LUCC) in Wuhan area using supervised classification method with a new
vegetation index based on universal pattern decomposition method (VIUPD). Land use dynamic index is also used to
analyze the temporal character and internal rule of number and construction of land use/land cover change. It shows that
the annual change ratio of different classification from 1988 to 2002 in Wuhan is -1.93% for river and lake, 4.86% for
breed water, 2.74% for construction, 0.58% for evergreen, 3.35% for deciduous, -1.08% for one harvest in one year farm,
-0.23% for multi-harvest in one year farm, 4.70% for other land use. And the formation and change mechanism of land
use/land cover in Wuhan is also analyzed systematically. It is found that the flat terrain of Wuhan provided a wide space
for land use expanding; the rapid increasing population accelerated the urbanization of the villages and towns nearby the
center city zone; and the economic benefit of land use made the change of different land cover.
The Virescence Separator of Beijing, the capital city of China, is a virescence zone between the central area and the edge group as well as the zone among different edge groups, within irregular shape and the total area of 240 square kilometers. The construction of the Virescence Separator is a big and difficult project, an effective information system for planning and development with satisfactory performance is therefore essential. In this paper, the applications of remote sensing and GIS (Geographical Information System) technologies in BJVSIS (planning and development Information System for Beijing Virescence Separator), including three dimensional (3D) visualization, integrated databases management and multi-media technologies, were presented. The initial pilot project of BJVSIS was finished successfully in 2001, and up to now this information system runs very well and plays a great role in the construction of the Virescence Separator. Just depended on the applications of so many high-tech like GIS, remote sensing, 3D visualization, and databases integration, BJVSIS can manage all kinds of relevant geographic data, such as vector graphics, DEM (Digital Elevation Model), image and multi-media attributes. And BJVSIS also provides many GIS functions, such as spatial query, 2D/3D display, spatial analysis, statistic calculation, form report and map output.
