摘要: 农村居民点“空心化”引发农村土地利用结构和布局转变,为研究农村居民点时空演变,从乡村振兴视角出发,以长春市九台区为研究区域,利用1990—2018年4期土地利用数据,基于ArcGIS 10.6和Fragstats 4.2,采用景观格局指数、平均最邻近指数、Voronoi图变异系数等方法,对九台区近30年农村居民点时空演变特征进行分析。结果表明,1990—2018年整体上农村居民点面积收缩,平均斑块面积增大。在斑块尺度上,农村居民点呈相对规则分布为主,边界曲折度较低。农村居民点整体分布呈现集聚性,但各乡镇和街道农村居民点分布多数呈现随机性,少部分呈现集聚性。农村居民点分布大致展现出“中部集聚,四周稀疏”的空间分布特征。2000—2010年高密度值区域明显收缩。农村居民点重心整体表现为向着长春中心城区偏移。该研究可为农村居民点整治和布局优化、土地资源的合理配置、农村生产生活空间的改善提供参考,从而进一步为推进乡村振兴和城乡一体化发展提供理论依据。

Abstract: The “hollowing” of rural settlements leads to changes in the structure and layout of rural land use. To study the spatial-temporal evolution of rural settlements from the perspective of rural revitalization, Jiutai district in Changchun was chosen as the research area, the land use data based on ArcGIS 10.6 and Fragstats 4.2 from 1990 to 2018 was adopted, and the methods including landscape pattern index, ANN index, and Voronoi diagram variation coefficient were used to analyze the characteristics of the spatial-temporal evolution of rural settlements in Jiutai district in the past 30 years. The results show thatOn the whole, the area of rural settlements has shrunk, and the average patch area has increased from 1990 to 218. On the patch scale, rural settlements are mainly distributed in a relatively regular manner, with low tortuous boundaries. The distribution of rural settlements generally shows agglomeration. The distribution of rural settlements in the towns and sub-districts is mostly random, and a few rural settlements are clustered. The distribution of rural settlements roughly shows the spatial distribution characteristics of “clustered in the middle and sparse around”. From 2000 to 2010, areas with high-density values shrank significantly. The center of gravity of rural settlements shifted to the center of Changchun. The research can provide a reference for the improvement and layout optimization of rural settlements, the promotion of the rational allocation of land resources, and the improvement of rural production and living spaces, to further realize rural revitalization and the development of urban-rural integration.
