Current situation and some intending problems of landscape spatial dynamic model

Along with the rapid development of remote sensing, geographic information system, computer and other supporting technologies, model approach has become the major method of landscape dynamic study. Based on literature review, this paper analyzed the current situation and some intending problems of the development of landscape spatial dynamic model. Three kinds of models, i. e., stochastic landscape model, neighborhood rule model and landscape process model (including percolation model, individual-based landscape model and spatial ecosystem model) were mainly introduced, and their development status, existing problems and related improvement work were analyzed. The development of model test technologies, such as verification analysis, validation analysis, and sensitivity analysis, were also analyzed. Finally, this paper summed up six major problems that should be dealt with in the future development of the landscape spatial dynamic models. These problems included model arithmetic optimization, scale conversion, model complication and predigesting, model test and assessment, bringing forward of general model, and integration of the traditional model with social-economic factors.
