Research on Expression Method of GDP Data Based on GRID

According to space-based socio-economic statistics of resources environment, calamity defense and calamity decrease, and the rapid application of the grid GIS, this paper uses the grid analysis technology and statistical analysis technology, studies the pertinence between the land-use situation and the spatial distribution of GDP through researching the relationships among all kinds of geographical variable, then establishes the spatial distributed model of GDP. On the basis of this model, the author establishes a spatial GDP datasets with 1 km grid of china in 2000 year. The method makes the in-depth application of GIS technology in the field of economic statistics more easily, makes the overlay analysis between the statistical data and other spatial data more easily, achieves the management, the analysis and the display of the statistical information taking advantage of GIS analysis functions efficaciously, and establishes the data foundation for further data mining and assistant decision-making.
