摘要
道路交通历来是聚落形成、空间分布与景观特征的重要影响因子。本研究基于田野调查、历史舆图、卫星影像、1:25万道路交通数据和居民点分布数据(2014),采用文献总结、GIS分析、数据统计等多元技术方法,探索岷江上游的交通干道如何影响乡土聚落的空间分布、形态格局与景观特征。研究表明:1、岷江上游交通闭塞、道路密度较低,其交通干道具有征伐迁徙、茶马贸易和现代交通干线等多重特征,并在空间上高度重合;2、交通干道影响着岷江上游聚落点的分布趋势和分布密度,且相较于水系而言,交通干道对聚落分布的影响力更强,83.48%的农村聚落分布在距交通干道3000m范围内,92.41%的乡镇聚落分布在距交通干道500m以内,城镇对交通有更强的依赖性;3、交通干道是聚落内部空间格局与景观风貌变化的重要影响因素。
Road traffic has always been an important factor in the formation, spatial distribution and landscape characteristics of settlements. Based on field surveys, historical maps, satellite imagery, 1:25 million road traffic data and residential point distribution data(2014), this paper uses literature summarization, GIS analysis, data statistics and other multi-technical methods to explore how Traffic artery in the upper reaches of the Minjiang River affect. Spatial distribution, morphological pattern and landscape characteristics of rural settlements. The research shows that: 1. The traffic congestion and road density in the upper reaches of the Minjiang River are low, and the Traffic artery have multiple characteristics such as conquest, migration, tea-horse trade and modern Traffic artery, and are highly coincident in space;2. Traffic artery affect the upper reaches of the Minjiang River The distribution trend and distribution density of the points, and the Traffic artery have a stronger influence on the settlement distribution than the water system. 83.48% of the rural settlements are distributed within 3000 m from the main roads, and 92.41% of the township settlements are distributed in the traffic. Within 500 m of the main road, the town has a stronger dependence on traffic;3. The traffic artery is an important factor affecting the spatial pattern and landscape changes of the settlement.
