陇川县农村居民点分布研究

以陇川县农村居民点为研究对象,综合运用GIS分析技术揭示农村居民点空间分布特征与规模空间差异。选取自然环境与社会经济两个方面影响因素,结合景观格局指数分析,研究各因素对农村居民点数量、规模及形状等方面的影响。结果表明:陇川县农村居民点整体分布为聚集模式,空间数量分布呈现由护国乡至城子镇的"带状"和户撒阿昌族乡、勐约镇的"点状"聚集,且农村居民点规模热点与核密度呈现明显负相关的空间特征。影响因素方面,耕地、道路对农村居民点空间分布影响较大,高程、坡度、城镇用地与工矿用地对农村居民点规模差异影响较大,形状特征受坡度影响最大,而交通对其无明显影响。     

基于GIS-SDA的居民点空间分布研究

空间数据分析(SDA)与GIS相结合是研究地理现象空间分布规律的重要方法。借助1994年和2004年两期RS图像,得到徐州市居民点空间分布数据,运用GIS-SDA方法研究徐州市1994年和2004年的居民点空间分布模式,并总结了11年间居民点空间分布的动态演变规律。通过最近邻距离分析(运用R统计量)得出徐州市居民点空间分布总体上呈现集聚趋势,且2004年的集聚程度比1994年低;通过计算居民点空间分布的K函数值,发现随着研究尺度的变化,1994年和2004年的居民点空间分布集聚程度均出现先增后降过程。运用核函数与泰森多边形法计算两个年份的居民点密度分布,核函数法能够从总体上反映徐州市居民点密度空间分布的地域差异,而泰森多边形法对居民点密度空间分布的细部差异较敏感。     

GIS支持下山区县域农村居民点分布特征研究——以栖霞市为例

运用GIS空间分析技术、景观指数法和Voronoi图Cv值相结合的分析方法,研究了胶东山区栖霞市农村居民点的空间均匀性特征,并探讨了农村居民点在地形梯度上的分布特征。结果表明:全市农村居民点分布的Cv值为58.84%,空间分布表现为随机分布;唐家泊镇、松山镇、臧家庄镇和翠屏街道4个乡镇的农村居民点呈集群分布,其他乡镇为随机分布;农村居民点分布的优势区间在1~3地形位,随着地形位的增大农村居民点的优势度降低;农村居民点的面积、斑块数目和平均斑块面积随地形位的增大而减少,平均斑块形状指数和平均斑块分维数随地形位的增大而增大;同时,公路是影响山区农村居民点空间布局的重要因素。研究反映了栖霞市农村居民居住习惯的差异,为农村居民点的整治和规划提供了依据。     

河西走廊城乡居民点空间分异特征及绿洲孕育度分析

绿洲和绿洲所孕育的城镇与乡村聚落是西北干旱区人类生产、生活和生态的核心，探究绿洲与居民点的关系对干旱区新型城镇化建设与乡村振兴意义重大。研究通过Google Earth目视解译，识别提取河西走廊全域绿洲和城乡居民点空间特征信息，运用GIS空间分析、景观格局指数，系统地对河西走廊2016年城乡居民点的规模、形态结构与类型特征进行分析，并首次提出了干旱区居民点的绿洲孕育指数，进一步分析了城乡居民点的绿洲孕育程度。结果表明：（1） 河西走廊居民点规模与密度分异特征显著，居民点用地规模普遍偏小，平均规模仅为0.05 km²。居民点分布呈现高密度小规模和低密度大规模集聚分布的特征，居民点密度和集聚度均以城市为中心呈距离衰减规律。“热点”探测发现，山丹县以东是河西走廊地区居民点分布的热点区。（2） 居民点形态结构分析表明乡村聚落的连接性和稳定性自东向西逐渐减弱，居民点面积差异性从城市“中心—边缘”在逐渐的缩小，其中瓜州县、玉门市和金塔县等区域居民点的平均形状指数和平均分维数耦合度高，自然分布态势强，斑块形状复杂。（3） 绿洲孕育指数较高的嘉峪关“人—地”关系矛盾突出，城乡发展极大受绿洲规模限制；而凉州区、民勤县等绿洲腹地空间宽广有利于城乡居民点发展。     

基于GIS的农村居民点分布特征及景观格局研究——以揭阳市为例

农村居民点作为乡村区域空间人口集聚形态的一种表现,是构成乡村聚落景观的一个重要部分,对其特征的分析研究对于推动城乡一体化建设和美丽乡村建设等政策的理论研究和实践开展和促进农村土地节约集约利用有重要意义。运用Ripley's K函数和ArcGIS 10.2中的核密度法来研究广东省揭阳市农村居民点的空间分布特征,建立河流和道路的缓冲区,从景观生态学的角度进一步分析影响居民点空间格局分布的因素,得出以下结论:(1)揭阳市农村居民点的空间分布格局属于集聚分布。(2)60%以上的农村居民点集中分布在由榕江、龙江和练江三大水系构成的河网体系周边。(3)农村居民点主要集聚在普宁、榕城、揭东、蓝城和空港经济区的县区范围。     

长沙市农村居民点空间格局特征研究

运用2013年长沙市的遥感影像数据,借助于空间插值、空间自相关分析以及空间变差函数等数学模型,对长沙市农村居民点的空间格局进行研究。在空间分布上,长沙市农村居民点空间布局呈现"西密东疏"的特征;在规模分布上,长沙市农村居民点的规模分布存在明显的空间随机独立性及空间分异性特征,并且出现高值聚簇区,主要分布在以浏阳市西北部的焦溪乡、淳口镇、北盛镇、山田乡等地为中心的周边区域;在形态分布上,长沙市农村居民点形态存在显著的空间分异格局,其形态分布的均质程度不高,呈现以中间区域为顶点向周边方向倾斜的结构,空间结构性差异显著,总体上呈随机独立分布状态。     

长沙市农村居民点景观格局变化及地域分异特征研究

以1989年、1999年和2009年3期Landsat TM影像及2005年的土地利用现状图为数据源,结合野外实地调查,应用GIS空间分析、重心迁移定量模型和景观生态学方法,对长沙市1989-2009年农村居民点的用地面积、规模、空间分布、形状的动态变化过程及地域分异特征进行了研究。研究结果表明: ① 20 a来农村居民点总面积及斑块平均规模不断扩大,农村居民点空间分布日趋集中和密集,斑块形状不断向完整与规则转变;② 农村居民点空间布局地域分异特征明显,在平均斑块面积、斑块密度等指标方面平原区、丘岗区与山区之间存在着显著差异;③ 20 a来,长沙市农村居民点的空间分布重心由西向东迁移,迁移距离为6.62 km。     

大城市边缘区农村居民点用地空间布局优化研究——对上海南汇地区的考察

大城市边缘区农村居民点用地存在用地粗放、布局散乱、难于规范管理等问题。以大城市边缘区农村居民点用地整理为契机,优化空间布局不仅有利于形成农村经济新增长点,还可促进农村居民点土地集约节约利用。在分析当地农村居民点用地现状及其分布状况的基础上,以典型地区——上海南汇地区为例,对其空间分布的随机性进行了检验,对农村居民点用地按标准偏差分类,并进一步按欧氏空间距离对大于2.25标准偏差的地块进行聚类分析。结果显示:南汇地区农村居民点用地的空间分布并不是随机分布,可分为远离中心类和集聚中心类两种类型。依据结果,提出了"远离中心方案"和"集聚中心方案"两种不同的农村居民点用地整理方案。     

城乡融合发展导向下农村居民点空间布局优化研究——以徐州市铜山区为例北大核心CSCD

农村居民点空间布局优化有利于推进国土空间治理、加快城乡统筹发展、改善生产生活条件,而城乡融合发展对农村居民点空间布局优化具有战略指导作用。该文以徐州市铜山区为例,构建城乡融合发展导向下农村居民点空间布局优化的理论框架及作用路径,据此建立适宜性评价指标体系,并根据适宜性评价结果,运用空间最大化覆盖模型对农村居民点空间布局进行优化。研究结果表明:研究区农村居民点总体适宜度评价值在25.66~79.83之间,适宜性空间分布总体呈现“中心高、四周低”特征,非常适宜区面积占研究区总面积的17.24%,主要分布在徐州市中心附近,不适宜区面积占总面积的65.81%,主要分布在铜山区北部和东部;铜山区农村居民点空间布局优化后共节约用地310.63 hm 2,且居民点用地集聚度与适宜性显著提升。城乡融合发展导向下农村居民点空间布局优化的关键是从城乡融合发展视角对农村居民点用地适宜性进行评价,研究结果可为村庄规划与农村土地整治等提供方法支持与借鉴,以农村居民点空间布局优化为抓手助力城乡融合发展。     

山区农村居民点可持续发展状态评价实证研究——以福建省宁化县淮土乡为例

农村居民点可持续发展状态评价对城乡协调发展与新农村建设有重要理论与实践指导意义。以宁化县淮土乡为研究区域,从反映农村居民点可持续发展的PSR(压力-状态-响应)模型构建了22个评价指标体系,采用主成分分析法把淮土乡农村居民点可持续发展状态划分为理想状态、较好状态、临界状态、较差状态。结果表明:(1)农村居民点持续发展的压力、状态与响应系统之间具有显然的共生发展关系;(2)居民点的可持续发展状态与当地居民对居民点发展的响应态度呈正相关;(3)居民点持续发展状态在空间分布上具有"毗邻连片"特点,且与规划的居民点整治与再安置区空间分布有一定的吻合性。
