摘　　要：当前乡村聚落正面临转型和空间重构,村镇体系已经成为亟待研究的重要命题。本文基于分形的相关理论和方法,以皖西南溪镇为实证区域,对大别山区村镇体系的空间特征进行了探讨。结果表明:(1)南溪的村镇体系结构一定程度上服从Zipf定律,村镇体系规模结构有待进一步优化调整。(2)无标度区范围跨度狭窄,村镇体系的分形发育不完善,其空间分布既非高度集中也非均匀分布,呈现出中间状态。(3)山区村镇的职业结构分化显著。从业人口中,职业结构分化显著,这将有利于山区城镇化的推进和村镇体系的空间优化,而非从业人口基本是老人和留守儿童,在今后的山区居民点调整中应给予充分关注。With the rapid development of industrialization and urbanization, the location evolution of rural residential areas has been an important research topic. The paper give a study on town and village system of Nanxi in Dabie Mountain based on fractal theory in Anhui province Three characteristics have been summarized： （1）The size of the hierarchical structure of town and village system of Nanxi comply with Zipf＇s Law to some extent. （2）The fraetal structure of town and village system of Nanxi is imperfect, according to the spatial correlation dimension, and the spatial pattem needs to be optimized. （3）The differentiation of rural occupational structure is conducive of town and village system in Nanxi. In the future the elderly and children should be paid to attention in the town planning.
