Abstract


At present, China 's third round of land use planning work is underway , the current round of land use planning is different from the previous two difference lies in planning land use planning to achieve the construction of the database . However, different decision-making levels require different scales of land use master plan , and as a platform for planning the construction of a database - GIS systems often require data to support different scales , which implies the need to build a database of different scales of planning . This work is undoubtedly a time-consuming , and would lead to data redundancy , data conflicts and memory increases and other issues. Therefore, if you can only build a large-scale planning a database , and then through computer graphics to achieve large-scale integrated planning database to the small-scale planning database conversion , will greatly reduce the above problem. This paper focuses township ( town ) level Planning Database ( large scale ) to the county Planning Database ( small-scale ) of cartographic generalization were studied. First, the analysis of land use planning data generalization of the theory ; Secondly, under the guidance of the theory of cartographic generalization , the establishment of a knowledge-based land use planning for the cartographic generalization rules ; Again, in theory , based on the study of the land use planning cartographic generalization implementation of key technologies , including ArcGIS achieved through land use planning cartographic generalization simple application process , and with the MATLAB programming to achieve a more comprehensive knowledge of the complex rules of priority classification of the implementation process ; Finally, planetesimals county and township ( town ) level land use planning database for the data source experimental system for 1:10000,1:25000,1:50000,1:100000 four kinds of scale were carried out a practical attempt cartographic generalization , and four kinds of scale combined result of a summary , evaluation, and effect diagram to compare. The results prove that this article cartographic generalization is reasonable and successful.
