中文摘要：
为了对农村居民点的土地利用现状进行分区研究，以临夏县北塬地区为研究区域，采用2010年临夏县土地利用数据为基础，利用景观格局分析软件得到代表北塬地区农村居民点特征的20个景观格局指数，运用主成分分析方法对这20个景观格局指数进行降维处理，得到能够代表这20个景观格局指数的3个指数，即仙侬多样性指数、斑块密度、形状指数。最后，运用聚类分析方法对北塬地区农村居民点进行分区。结果表明：北塬地区农村居民点可以分为4类：第1类为北塬乡、南塬乡；第2类为土桥镇、桥寺乡、先锋乡；第3类为坡头乡、安家坡乡、河西乡；第4类为莲花镇。研究结果对今后的北塬地区土地利用总体规划，农村居民点整理，新农村建设工作具有重要意义。
