Based on 2000 and 2012 remote sensing image interpretation results, using the extended dynamic analysis method, the quadrant orientation analysis method, concentric circle analysis and land use conversion analysis, r we analyzed the characteristics and patterns of urban settlement land expansion in Xiaguan Town. The results indicate that in the last thirteen years, the overall expansion situation of urban settlement land in Xiaguan Town was obvious, showing a clear north-south differentiation, the scale and speed of land expansions in the south were much lower than those in the north; 2 000~2 500 m and 3 000~3 500 m circle from the town government is the main expansion area of urban settlement land; with the expansion, urban settlement land elevation rose, low slope hilly area was the first choice for land expansion. With time going on, the plaque fragmentation degree of the newly-built urban settlement land is higher and its shape is complex, which is obviously influenced by human activities, mainly by the conversion of cultivated land and non-settlement artificial land, showing three types of expansion patterns, such as urban expansion-driven pattern, traffic-induced pattern and industrial development derivatives.
