Research Advances in Landscape Pattern and Dynamics

Landscape pattern researches include composition analysis,diversity and heterogeneity of landscape types.The common used analysis methods of landscape composition are geostatistics,clustering variance analysis,tend surface analysis etc.Landscape diversity includes landscape type diversity,pattern diversity and patch diversity.Diversity index,dominance,evenness and richness are the usually measured indices describing diversity of landscape types.The criteria of patch number,area,shape,fragmentation and fractal dimension are commonly adopted to describe the patch diversity,whereas the commonly applied indices to measure the landscape pattern diversity include modified fractal dimension,aggregation index and continuity.The researches of landscape heterogeneity have mainly focused on the formation mechanism of landscape heterogeneity and the influences of heterogeneity on ecological process of the landscape.The researches of landscape dynamic have been concentrated on analyses of landscape dynamic variation,simulation and driving factors to cause the change.The integrated measures of remote sensing and GIS technologies are being popularly adopted to analyze dynamic changes of the landscape.In aspects of landscape dynamic simulation models,application of self-organizing cell model and Markov model has been mostly researched.The researches of driving factors of landscape dynamic have mainly focused on human-driven aspects,and there is not yet mature study method.
