摘要:

随着工业化和城镇化的快速发展,农村聚落功能多元化趋势明显,空间异质性深化,但针对农村聚落功能的专门研究并不多见。从效用价值理论和供需分析视角出发,剖析了农村聚落功能的服务内涵和时空动态特征,提出农村聚落生产、生活和生态功能分类体系,构建了功能评价指标和基于信息熵的综合评价模型,以村为单元进行了实证分析。分析表明:农村聚落功能空间分异特征显著,案例区西部和北部远离城镇、交通干线地区农业生产功能较强,城镇周边以及沿江地区工、商、文化教育等功能集聚,东北部吕四港地区休闲娱乐和自然人文景观保护功能较强;农村聚落功能多元化发展在空间上呈现“多中心”的格局特征,从“中心”向外围地区,随着距离增加,聚落功能多元化程度逐步衰减,且不同“中心”的功能构成存在明显的空间差异

Abstract:

With the rapid development of industrialization and urbanization, the rural settlements function has shown an increasingly strong trend towards spatial differentiation and diversification. Though discussion on rural settlements is becoming hot, little special attention has been given to rural settlements function. From the viewpoint of utility theory of value and concept of demand and supply, this paper discussed the meaning, classification and spatial heterogeneity and temporal variability of rural settlements function, then a multifunctionality assessment index system and an index analysis model were set up, later, based on the village scale, this paper evaluated and graded the functions of agricultural production, industrial production and commercial trading, daily life, health services, cultural and educational services, ecological service protection and comprehensive function. The results were as follows. Agricultural productionoriented functional areas were mainly distributed in western and northern areas which were far from the city and highway. Industrial production and commercial tradingoriented areas and culturaleducational servicesoriented indices were gradually weakened from city and towns to remote areas and from areas along the Yangtze River to the north. Ecological and cultural conservation areas were concentrated in the northeastern part. The composite function on the village scale emerged polycentric structure in the Qidong City. With gradually increasing distance from the strong function center, the composite indices became smaller, meanwhile, the function types of strong center were different from each other
