摘要
以辽宁省新宾县作为研究区,采用TM影像及第二次土地调查数据库为主要信息源,经遥感解译和实地确认获得乡村聚落空间分布信息,运用GIS空间分析功能通过自然地理环境、交通、城市化等因素对乡村聚落空间分布特征进行定量化分析。结果表明:聚落分布与海拔存在一种非线性的关系;聚落主要沿河流与道路的两侧分布,属典型的线轴型聚落;少数乡村聚落分布于高海拔偏远地带,远离交通干道,基础设施不完善,也不利于脆弱生态环境的保护,对此应进一步深入研究,为居民点规划提供参考。
Taking xinbin County in Liaoning Province as a research area, the TM image and the second land survey database as the main information sources, confirmed by the remote sensing interpretation and investigation on the spot to obtain the spatial information of rural settlements, a quantitative analysis through natural geographical environment, transportation, urbanization and other factors on the spatial centralization of rural settlements in xinbin county was made based on the spatial analysis technique of GIS. It is found that there is a nonlinear relationship between settlement distribution and elevation. Settlements as a typical spool-type settlement were mainly distributed along rivers and both sides of the roads; the minority rural settlements with imperfect infrastructure located in high altitude remote areas, and it were far away from traffic roads, which were inadvisable for the protection of fragile ecological environment. It should be further studied to provide a reference for the settlement planning.
