摘要: 农村居民点是农村居民为生产和生活便利修建的固定住所,社会表现为农村居民空间的聚集,其时空演变与景观格局变化受当地自然环境、传统文化、经济发展等多种因素影响。本文通过成都平原边缘洪雅县1997年、2006年和2015年三期遥感影像,借助RS、GIS软件提取农村居民点数据,结合DEM高程及坡度数据,研究了洪雅县农村居民点的时空演变及景观格局,并分析了其影响因素。结果表明:(1)1997年至2015年18年间洪雅县农村居民点的空间分布总体表现为更加聚集,地理聚集方向没有变化,持续地逐渐集中于该县北部平缓区域。(2)坡度对洪雅县农村居民点的布局影响强烈,农村居民点中超过70%分布在0-5°范围内。随坡度的升高,农村居民点的斑块数及斑块面积总体上均表现为先降低后回升再降低。(3)海拔对洪雅县农村居民点的布局影响显著,<500 m范围其集中了超过55%的农村居民点。从1997年至2015年洪雅县农村居民点变化结果及趋势来看,农村居民点空间分布呈现逐渐优化过程,农村居民点有从高海拔地域向低海拔城镇迁移趋势明显。研究以期为成都平原边缘典型地貌区的社会主义新农村规划、土地开发整理等项目提供参考。

Abstract: Rural settlement is the settled places that rural population living for agricultural and non-agricultural activities, and the social performance is the space gathering of the rural resident, it’s spatial and temporal changes and landscape pattern changes are influenced by many factors, such as natural environment, traditional culture, economic development and so on. In this paper, Through the data of three remote sensing images of Hongya County in 1997, 2006 and 2015 and combining with DEM elevation and slope data ,the spatial temporal evolution and landscape pattern of rural residential area in Hongya County were studied, and its influence factors were analyzed. The results show that:(1)From 1997 to 2015, the spatial distribution of the rural residential areas in Hongya County in 18 years shows a tendency of getting to together, and there is no change in the direction of geographic aggregation, which constant gradually focuse on the north of the Hongya County.(2)Slope of Hongya County had a great effect on the layout of the rural residential areas,,and rural residents more than 70% point distribution in the range of 0 to 5 °.Along with the increase of slope,the number of patches and patch area of the rural residential area are all shown as the first decrease and then decreased.(3)Altitude has significant influence on the distribution of rural residential areas in Hongya County,more than 55% of the residential distribution in the range of 0 to 500 m. From 1997 to 2015 in Hongya County, the rural settlements change trendSshows that the distribution in gradually optimized, farmers go down the hill and along the urban agglomeration is obvious. The research in order to provide reference for the new socialist countryside planning, land development and consolidation projects in the edge of Chengdu Plain.
