- 摘要:
- 居民点的空间布局是新型城镇化研究中首要厘清的问题之一。以陕西省新型城镇化试点——杨陵区为研究对象，通过遥感影像解译获取居民点的空间布局形态，基于层次分析法（AHP）构建相应评价体系和模型，并结合景观格局分析方法和GIS技术，研究了居民点用地适宜性。评价结果表明：（1）杨陵区居民点布局总体较好，现有居民点布局表现出规模集中化和局部分散化并存现象；（2）区内居民点分布受海拔、坡度等自然因素以及道路通达性等社会因素的影响明显，居民点主要集中分布于相对海拔较低、坡度较平缓、离公路较近的区域内，而与渭河的距离影响不敏感。研究结果对后续杨陵区居民点整理和土地资源的规划与利用提供了参考，采用的方法具有可行性和一定的科学性，为不同区域居民点用地适宜性的评价提供了定量的分析方法。
- Abstract:
- Clarifying the layout of residential area is one of the main issues in research of new pattern urbanization. This article takes Yangling District as the case of study, which is a pilot city of new pattern urbanization. Firstly, we obtained the spatial distribution of settlements with the remote sensing technology. Secondly, we established an evaluation system by analytic hierarchy process. Finally, we used the method of landscape pattern analysis and GIS technology to study the suitability evaluation of residential area. The results show that:(1) spatial distributions of settlements in Yangling District are basically favorable, the layout of the present settlement displays a mainly central tendency and the scattered pattern in part; (2) natural factors such as altitude and slope and social factors such as accessibility to roads have great effects on the layout of settlement, while distance from Wei River has little influence. The residential area is mainly located in areas of the low altitudes, gentle slope and near road. The results can provide the reference for the follow-up works that include consolidation of residential area and land resources planning. This method is scientific and applicable in this field, and shares the quantitative analysis method for the suitability evaluation of residential area in different regions.
