福建省闽侯县乡村聚落空间格局与可达性研究

Research on Pattern and Accessibility of Settlements of Minhou County in Fujian Province

运用空间分析法与时间成本分析法,以福建省闽侯县329个自然村为研究对象,分析闽侯县自然村的空间格局,计算各自然村到所属乡镇(街道)政府驻地的交通可达性,并对其交通可达性的特征与影响要素进行分析。研究表明:(1)闽侯县自然村空间格局呈现总体分散、局部集中的分布特点,县域南部自然村集聚程度高于北部,除局部高密度区外,自南向北核密度逐渐降低;(2)闽侯县自然村交通可达性总体较好,可达时间为5~104 min,约95%的自然村分布在离所属乡镇(街道)政府驻地60 min的车程之内;闽侯县自然村到县城所在地甘蔗街道的可达性差异巨大,仅有44%的自然村分布在60 min的车程内;(3)影响自然村分布的因素有空间格局、地形、河流、交通和城镇化等。

In this paper, GIS analysis and time-cost analysis were used to calculate the traffic accessibility of 329 settlements in Minhou county of Fujian province. The spatial analysis method was used to analyze the spatial pattern in Minhou county, calculate the traffic accessibility of settlements to each township, and the characteristics and influencing factors of traffic accessibility were analyzed. The results showed that:(1) The settlements in Minhou county were clustered overall and dispersed in some places, the concentration degree of settlements in the south of the county was higher than that in the north, the nuclear density was gradually reduced from south to north, except for the local high density area.(2) The accessibility time of settlements in Minhou county ranged from 5 to 104 minutes, and the accessibility of settlements in Minhou county varied greatly, about 95% of the settlements are within 60 minutes drive from the township. The difference of accessibility of settlements in Minhou county to the Ganzhe street where the county seat is located was huge, and only 44% of the settlements are within 60 minutes.(3) The factors affecting the accessibility of settlements were spatial pattern, topography,rivers, traffic and urbanization.
