| 1 | Some Investigations on Early Organization of Karst System显示文摘Some investigations on the early organization of karst system are carried out through modeling the dissolution evolution processes of stochastic fracture networks in carbonate rock. It is assumed that water flow in fracture network is laminar, and the dissolution rate process can be described with an empirical equation, The results suggest that a karst system is a self-organization system. It can spontaneously create higher hierarchical level out of a relative homogeneous structure through amplifying the microscopic heterogeneity of initial flow field. Under given boundary conditions, a karst system with initial fracture network of varied hierarchical levels is likely to have stronger tendency to lead to a typical karst system featuring conduit passages than a system with initial network of unique hierarchical level. Through merging local flow systems, a karst system concentrates the limited flow into a few pathways to promote the formation of higher hierarchical level. | Yu Qingchun(Geofront Laboratory, Department of Civil Engineering, Kyoto University, Kyoto 606-8501, Japan)Shen Jifang Wan Junwei(Department of Hydrogeology and Environmental Engineering, China University of Geosciences,Wuhan 430074, China)Ohnishi Yuzo(Geo | 1999 | Journal of Earth Science1999，18，4： | 8 |
| 2 | Multiresolution Terrian Model in GIS显示文摘DEM, which becomes a major component of geographic information processing in earth and engineering sciences, has been studied in the GIS literature for a long time. We use DEM to represent the terrain in GIS. The more data are available, the better representations of a terrain can be built. But not all tasks in the framework of a given application necessarily require the same accuracy, and even a single task may need different levels of accuracy in different areas of the domain. Multiresolution models, such as LOD, offer the possibility of representing and analyzing a terrain at a range of different levels of detail. In this paper, some key issues in multiresolution DEM model are studied. Three main models are focused on Hierarchical TIN(HTIN), multiresolution terrain model based Delaunay and Hierarchical Dynamic Simplification. The advantages and disadvantages of these methods are analyzed. The technology of tile to tile edge match is studied to maintain the consistency between adjacent edges and tile edges in HTIN model. And the Hypergraph based Objected oriented Model(HOOM) is presented to divide and code spatial area and describe the terrain feature in adding and deleting points based on Delaunay rule retriangulating. The conclusions have been drawn in the end. | ZHANG Jin 1,TONG Xiao hua 2 (1. Department of Surveying and Mapping, Taiyuan University of Technology, Taiyuan 030024,China 2.
