| Abstract: | To solve the drawback of detection patterns of land use changes in our country, this article comes up with the business-driven mechanism for finding land use changes and then studys about the technical implementation methods of this mechanism,raises technology for finding land use changes by capturing the changes in database of land mangement business information system, then uses Oracle GoldenGate for technology implementation and experimental application. The results indicate that this technology can capture land use changes information timely and effectively ,and can drive the routine field inspection and routine updating of land use data. |
