摘要：
3D reconstruction based on high-level features, such as line and plane, is a significant development trend in Digital Photogrammetry and Computer Vision. Moreover how to rapidly realize 3D visualization of street landscape is very important for cyber city's 3D modeling. In order to improve efficiency of street 3D visualization and reduce humancomputer interaction, a scheme with high feasible and high automatic approach to auto-reconstruct 3D street elevation is presented by means of line matching solving orientation elements by vanishing point auto-rectifying and automosaiking large obliquity-angle close-range sequential images auto-recognizing concavo-convex edge of street elevation. Our approach for 3D-reconstruction bases on the feature of line and plane, which is also independent of model parameter vectogram or assistant of space point cloud. Experimental results prove that reconstructed 3D modeling is correctness, effectiveness and feasibleness by our method, which has high degree of automation and should be able to meet the need of rapidly visualizing 3D street elevation landscape.

摘要：
With the technology of Remote Sensing (abbr. RS) and Geographic Information System (abbr. GIS), We had gained the wetland landscape spatial database and attribute database of Hubei province from land-use maps, TM images, we have an investigation of the condition of wetland resources in Hubei Province. According to The results of the remote sensing survey and comprehensive analysis, it is showed that, around 2005, the total areas of wetland resources of Hubei Province were 36308.04 km 2 , excluding the area of paddy field, it is 16,551.58 km 2 . Among the whole wetlands of Hubei Province, paddy fields hold 54.41%, pond wetlands hold 19.46%, river wetlands hold 14.90%, lake wetlands hold 8.33%, beach lands hold 2.00%, and marsh lands hold 0.90%. According to the changes of the areas of the wetlands, we can see that the areas of lake wetlands and paddy fields had been decreasing while the areas of river wetlands, pond wetlands, beach lands and marshlands had some increase.

摘要：
Jianghan Plain is one of the most important commodity grain-, edible oil-, and cotton-growing areas. There are 764 thousand hm<sup>2</sup> of medium-low yield fields in the area affected by waterlogged soils, which accounts for 40.6% of the area of anthrosols. We chose Sanhu Farm as a study area to research if the present land use patterns match the physical properties of anthrosols profiles. Eleven soil profiles were randomly selected and samples from respective soil horizons were taken back to the laboratory for selected physical analyses. Measurement of some physical properties of the 11 profiles such as hardness and water table were made in the field, while water content, bulk density and porosity of every soil horizon were analyzed in the laboratory. The results show that land use patterns of four profiles did not match their soil physical properties totally;the physical properties of other three profiles needed to be modified in some way to match the present land use patterns. There are low water table and poor drainage problems in some profiles. Changes to soil use patterns, improve drainage ability and application of more organic fertilizers should be prime measures to improve soil producing ability in this area.
