ZhongShan Tomb Geographic Information System (GIS) And The Tentative Study On Landscape Structure Evaluation

An advanced software development method--integrated developtechnology is used in this design, which achieve the integrated management of spatial and attribute data of sub-compartments and compartments of ZhongShan Tomb(ZST) under the support of GIS OCX MapObjects. More efficient object-oriented programming language Visual Basic is adopted as software platform. Through the implementation the ZST forestry management work efficiency is improved and the work intension is lightened significantly.This local GIS include 3 main functions: browsing and modifying the data of sub-compartments and map layers, two directions of query between special and attribute data, the outputting thematic maps and reporting statistics tables.This system supplies landscape structure evaluation and scaling analysis of ZST scenic forestry. The indexes of diversity, evenness, dominance, isolation, fragmentation and fractal dimension are used in this study. The landscape structure evaluation was from three levels, which are sub-compartments, compartments and work region. Used stores per square kilometer of forest and TM4 remote sensing image the author give the scaling analysis. The result shows that the diversity of ZST is high but the evenness is low. The broadleaf forest is the main type of ZST forest. We can manage the ZST scenic forest in three layers.By using Windows98 as the running platform, the system advantages of rapid speed of processing data and tolerant errors, and can be operated conveniently and used easily.In general, this GIS has following characters:I) This GIS provides strongly query function for sub-compartments and compartments such as from map to table, from table to map and from table to table;II) This GIS provides strongly report outputting function;III) This GIS create ZST Landscape Structure Evaluation function.
