Abstract


Land-use in different size scales have different characteristics, the impact factor of one research scale in the other scale may not play a role. With statistical methods and GIS technology, papers analysed the spatial distribution of impact factors and scale effect of the land-use of Hanwang town, from the aspects of the natural environment, socio-economic conditions as well as infrastructure and other conditions. Considering the nine kinds of major land use patterns and the impact of six candidate factor and according to the spatial distribution and impact factors do space processing, which land-use data from the detailed investigation of land-use data. We make 100m×100m, 150m×150m ~ 500m×500m spatial scale sequence data a number of layers which generated on the basic research unit of 50m×50m. Discuss the scale effect of the spatial distribution of land-use impact factor in Hanwang town impact factor by constructing different sizes were constructed through the spatial distribution of land-use model-driven. Study shows that, not only model with the ability to explain changes in aggregate size, but also impact factor and its impact on their own research with the scale factor also occurred in varying degrees of change. These all show significant scale dependence of the law. The spatial distribution of Hanwang town is mainly affected by distance from the towns .
