Research on Spatial Knowledge Reasoning about Jiangzhai Settlement in First Period

According to the analysis of settlement configuration of Jiangzhai in its first period, this paper places emphasis on the spatial knowledge reasoning about the characteristics of vector graphs of relics. With the special designed spatial rule knowledge base put into practice, this paper adopts the precondition base and the consequent base to respectively store the precondition and consequent of spatial knowledge rules. In addition, with the help of rules of the spatial data mining and extraction, it makes a case study on the spatial knowledge reasoning about two house relics in the prehistoric Jiangzhai settlement through three methods of reasoning, ordinal reasoning, converse reasoning, and mixed reasoning that combines ordinal and converse reasoning together. What’s more, with a desired effect, the research successfully introduces ideas and methods into the study about the interior structure of site in the single settlement site.
