【摘要】：基于2000年、2012年两期遥感影像解译结果,运用扩展动态分析法、象限方位分析法、同心圆分析法及土地利用转换分析法,对下关镇城镇聚落用地的扩展特征及模式进行分析。得出以下结论:13年间,下关镇城镇聚落用地整体扩展态势明显,呈明显的南北分异,南部地区用地扩展规模与速度远低于北部;在距离镇政府2 000~2 500m及3 000~3 500m的圈层范围内为城镇聚落用地的主要扩展区;随用地扩展,城镇聚落用地海拔整体提升,低坡缓丘地区为用地扩展的首要选择。随时间演进,新建城镇聚落用地斑块破碎化程度较高、形态复杂、受人类活动影响明显,主要由耕地和非聚落人工覆被用地转入,呈现出城镇扩张推动型、交通干线引致型及工业发展衍生型等3类扩展模式。
[Abstract]:On 2000 2012, the two remote sensing image interpretation results, using the expansion method of dynamic analysis, quadrant analysis, concentric circle analysis and land use conversion analysis method, analysis of Xiaguan town settlement with expansion characteristics and mode. The following conclusions: 13 years, under the town of urban settlements land overall expansion the situation is obvious, obvious north-south differentiation, scale and speed is far lower than the northern expansion land south of the town government in the distance; 2 000~2 500m and 3 000~3 500m circle within the scope of urban settlements with major expansion area; with the expansion of urban settlements, land elevation integral lifting, low slope is the first choice for hilly areas land expansion. Along with the time evolution, the new urban settlements land fragmentation degree is high, complex shape, influenced by human activities, mainly from cultivated and non artificial cover land into settlements, a There are 3 types of expansion models, such as the expansion and promotion of cities and towns, the induced type of traffic trunk lines and the derivative of industrial development.
