Both primary and secondary data were used for this study. Primary sources of data include Global Positioning System (GPS), Landsat TM and ETM+ imageries of 1984, 1990, 2000, and 2011. Secondary data included administrative map and population data of the study area. Descriptive statistics and geospatial technique were used to analyse the data collected. The results showed a random pattern of settlement distribution in the study area. Results revealed that settlements covered about 0.52% of the total land area in 1984;1.32% in 2000;and 3.78% in 2011. Whereas linear pattern of growth characterised the periods between 1984 and 1990;clustering, infilling, and fringes were the patterns of growth that characterised the periods between 1990 and 2011. The study predicted that, at an average 1.2% of annual growth rate, settlements will occupy about 44.37% of the total land area by 2031. The study concluded that settlements in the study area varied in the patterns of distribution;the area was dominated by indigenous settlements type with overconcentration of social and economic infrastructures in few centres.展开更多
以定远县县域的农村居民点为研究对象,基于1980年、1990年、2000年、2010年和2020年的土地利用数据,运用核密度估计法、景观格局指数法、空间自相关等多种空间分析方法,深入研究了农村居民点规模、空间聚集、形态特征的变化趋势,并通过...以定远县县域的农村居民点为研究对象,基于1980年、1990年、2000年、2010年和2020年的土地利用数据,运用核密度估计法、景观格局指数法、空间自相关等多种空间分析方法,深入研究了农村居民点规模、空间聚集、形态特征的变化趋势,并通过普通最小二乘法(Ordinary Least Squares,OLS)和地理加权回归模型(Geographically Weighted Regression,GWR)分析了驱动农村居民点空间格局变化的因素。结果表明:定远县农村居民点规模呈现轻微增长,大小居民点融合显著,反映了农村地区人口迁移与集中化的动态发展趋势;空间聚集趋势显著,呈现“南部大范围连片,中部小范围分散”的特征;形态演变趋势相对稳定,但时空上表现多样;驱动因素分析表明定远县农村居民点空间格局早期以自然环境为主,后期受城镇化的影响,交通区位和社会经济因素的作用逐渐增强。研究结果可为中部地区农村居民点空间布局优化提供科学依据。展开更多
