The countryside is the habitat of food, ecology, and culture, and the indispensable basis for human survival and development. Assessing the spatial and temporal evolution of rural settlements contributes to the promotion of rural scientific developments. This study used the fractal theory, center-of-gravity model, and spatial syntax to analyze the spatial and temporal evolution of Shenyang Ciyutuo Subdistrict and its influencing factors based on geospatial data from 2009‒2019, from the perspectives of internal characteristics and external morphological changes. In terms of the external characteristics, from 2009‒2019, the compactness index increased from 0.414 to 0.454, the expansion rate increased from 1.17% to 3.11%, and the expansion intensity increased from 0.05% to 0.15%. From 2014‒2019, the western part of the subdistrict experienced the maximum expansion rate and expansion intensity. The center-of-gravity of the construction land shifted to the west and southwest. The internal characteristics of land use depended on geographical conditions. Clusters of rural settlements were formed in a north-south direction due to the topography and along the riverside in a band-like manner. From 2009‒2019, the integration level of the subdistrict improved and the scale and number of integration axis increased, forming a multicore tree-shaped structure. Pearson’s correlation analysis showed that urbanization is the main factor affecting the spatial and temporal land-use evolution, with transportation convenience, industrial park, and proximity to the river having little effects. This study provides a theoretical basis for the development of Ciyutuo Subdistrict and provides a reference for the development of similar commercial towns.

城镇空间形态演变及其影响因素的二维分析

农村是食物，生态和文化的栖息地，是人类生存和发展不可或缺的基础。评估农村居民点的时空演变有助于促进农村科学发展。本研究运用分形理论，重心模型和空间句法，从内部特征和外部形态学的角度，基于2009-2019年的地理空间数据，分析了沉阳慈鱼ut街道的时空演变及其影响因素。变化。从外部特征来看，从2009年至2019年，密实度指数从0.414增加到0.454，​​膨胀率从1.17％增加到3.11％，膨胀强度从0.05％增加到0.15％。从2014年至2019年，街道西部地区的扩张速度和扩张强度最大。建设用地的重心向西和西南转移。土地利用的内部特征取决于地理条件。由于地形的缘故，农村居民点集群沿南北方向形成，并沿着河岸呈带状。从2009年至2019年，该街道的集成水平提高，集成轴的规模和数量增加，形成了多核树形结构。皮尔森（Pearson）的相关分析表明，城市化是影响土地使用时空演变的主要因素，交通便利性，工业园区和靠近河流的影响很小。
