Simulation Of Temporal And Spatial Dynamic Changes Of Land Use And Landscape Pattern In Nanning Citybased On CLUE-S Model

With the growth in population, human contradictions have becomeincreasingly prominent, due to land use change caused by human activities andlandscape that changes in the Earth’s surface mounting。Landscape changesaffecting the changing regional environment, dynamic change of landscapepattern in one has now become the focus of landscape ecology research at homeand abroad。 Through research to better understand the ecology of thelandscape, reveal the landscape succession laws and mechanisms to achievesustainable use of resources。This research combination GIS and RS technology, to TM remote sensingimage data for relying on, to landscape ecology principle for Foundation, underthe guidance of systems theory, information theory and cybernetics, analysis ofstudies on land use and landscape pattern in Nanning city, based on the twoimage data interpretation, calculation out target years land using landscapeneeds file, then combination select of8species drive factor, application CLUE-Smodel simulation target years land using landscape pattern changes。This research includes the following main aspects：（1）Processing of remote sensing image data。This article choose ERDASIMAGINE to deal with remote sensing images, through geometric correction,image enhancement, image stitching, cropping an image, band combinationsare research areas of remote sensing images, then it is interpreted, are land useand landscape pattern in the study area map。（2）Land use and landscape pattern analysis. This article select number ofplaques, plaque density, patch size index, index of average indices of shape, degree of separation, fragmentation, and other indicators, Use landscapepattern indices software Frgastats， after interpreting images of landscapepattern indices, according to results analysis of land use and landscape pattern。（3）Applying the CLUE-S model simulation of land use and landscapepattern in2005year2009land use and landscape pattern， number of grid tobe simulated correctly for6,307,860, Total number of grid7,154,364of the88.17%，so Po=0.8817，the resulting Kappa index of0.8512. Simulation effectsbetter, explains CLUE-S model is a good simulation of land use and landscapepattern change in Nanning. CLUE-S model can be applied to different scenariosof land use and landscape pattern of land use and landscape pattern change inthe model of simulation。（4）Simulation in2005as the initial data set under three programmes ofland use and landscape pattern change in2015, simulation results show thatthe three simulated scenarios of land use and landscape pattern in space, thereis a big difference。...
