This paper is devoted to introducing the concept and ideas of GeoComputation (GC) to Chinese geographers. GC is regarded as the application of computationally intensive approaches based on high performance computing to solving geographical problems and to explaining geographical phenomena. One of the origins of GC is linked to computational science with a principle of the use of models to gain understanding. GC includes all the tools of quantitative geography, but it is not the development of quantitative geography. GC was covered in some GIS books, but it is not another name for GIS. In addition to the greater computational efficiency and fuzziness provided by computational intelligence technologies, GC can improve the quality of study results by using computationally intensive methods to reduce the number of assumptions and eliminate the irrelevant simplifications imposed by computational constrains. A problem is that we don’t know what ‘core GeoComputation’ is. In order to make the diverse research efforts on GC convergent, we should have computational geography become the principal part of GC, which seems to exceed the limit of geography.
