Research on Spatial Variation of Land Use and Landscape Pattern in Baise Youjiang River Valley
As a case study of Youjiang river valley of Baise ,we use TM data acquired in 2005 and 2011 ,the technology of GIS&RS ,the principle of landscape ecology and several landscape index ,to make quantified analysis of the landscape area of dynamics in spatial and temporal change process ,in-cluding the landscape pattern change space differentiation characteristics as well as analytical space dif-ferentiation which produces driving force using Arc /Info ,Erdas imagine and Fragstats 3 .3 software . T he results show that the general trend of the land use change is the increase in construction land , grassland ,water body and unused land ,and the decrease in farmland and forest ;the landscape pat-tern change mainly represents landscape fragmentation trend and intricate landscape forms ,and the ecological system is heading in the direction of diversity .The spatial variations are mainly driven by spatial differences in geomorphology ,population density ,road network ,etc .Human activity and eco-nomic development are the primary driving factors of change in the landscape pattern .
