摘要:
乡村路网是山区重要基础设施。乡村路网的合理规划与建设对乡村可持续发展具有重要意义。前期研究多集中于单一时间段,以乡镇为研究单元来探讨山区乡村路网通达性; 缺乏以行政村为研究单元,居民点为节点对乡村路网多时段的研究,难以揭示山区村级水平路网的时空变化规律。本文以位于武陵山区的秀山县为例,基于2000年、2010年和2020年3期乡村路网数据,运用网络分析法、SOM聚类和地理探测器方法分析乡村路网通达性时空特征,划分通达性分区并提出分区优化策略。结果表明:(1)秀山县乡村路网复杂性以及区域内连通性增强,初步形成网状交通网络。(2)2000—2020年秀山县乡村路网通达性呈上升趋势,行政村路网通达性得到改善,典型山区乡村路网通达水平逐步提升。(3)秀山县乡村路网通达性空间分异受自然和人文因素共同影响。坡度、高度、人口密度、自然灾害点、经济水平发展均呈正相关。优化后的秀山县通达性可分为低通达区、较低通达区、较高通达区、高通达区4种类型。(4)未来典型山区可通过不同分区通达水平结合自然、社会条件因地制宜提出优化策略,有效提升山区乡村路网通达性水平。本文对典型山区乡村路网通达性时空演变特征进行研究并分区优化,可为其他山区乡村路网发展建设和乡村振兴规划提供科学依据。
Abstract:
Rural road networks are essential infrastructures in mountainous areas of China. Reasonable planning and construction of rural road networks are of great significance to the sustainable development of rural areas. Previous studies explored rural road network accessibility by a single period with townships as research unit in mountainous areas; however, there were lacks of research on multi-period rural road networks with administrative villages as research unit and settlements as modelling nodes, making it difficult to reveal the spatial-temporal variation of road networks on a village level.
In this study, it took Xiushan County in the Wuling Mountains of China as case study to exemplify the spatial-temporal characteristics of rural road network accessibility on a village level. It analyzed rural road network data of 2000, 2010, and 2020 using network analysis, SOM clustering, and geographical detector methods, followed by accessibility zoning and optimizing strategies.
In the typical mountainous villages of Xiushan County, it promoted the complexity of road network and connectivity, forming a preliminary reticulate transportation network.
From 2000 to 2020, the accessibility of the rural road network showed an upward trend, with road network accessibility to be improved on a village level, accompanied by a general increase in the accessibility levels of rural road networks in the county.
There was a large spatial difference in the level of road network accessibility in the county, which was jointly influenced by natural and human factors. Slope, elevation, population density, natural disaster sites, and economic development level were positively correlated with accessibility, with a decreasing order: slope> natural hazard points> economic development level> elevation > population density. The optimized accessibility for the county could be divided into four types: low accessibility area, lower accessibility area, higher accessibility area, and lowest accessibility area.
It could be suggested that for effective enhancement of road network accessibility in typical mountainous regions, optimization strategies should be based on the accessibility levels of different zones combined with natural and social conditions.
This research provides a scientific reference to the development and construction of road networks and rural revitalization planning in similar mountainous areas.
