The physical texture of cities is comprised of built-up spaces, open-green spaces, and transportation arteries. Urbanization is a dynamic that compose of each of the factors above in a fair proportion to human beings and nature. On the other hand, due to the rapid increase in urban population, urbanization has become a concept that poses serious problems for cities in the last decades and this leads a pressure on open-green spaces in urban areas. Open-green spaces have a great importance in improving urban life conditions and balancing the destroyed relations between humans and environment. For this reason, the sustainability of urban open-green spaces cannot be ignored in the planning studies. In this study, the change in the urban texture in Nevsehir (Turkey) was evaluated in a 10-year period (2004-2014) through the integration of remote sensing (RS) and geographical information systems (GIS). Through the use of satellite images with high ground sample distance-QuickBird (60 cm) (2004) and Worlview-2 (50 cm) (2014)-the direction of urban expansion and changes which occurred in urban open-green spaces and urban development areas were examined in detail at the whole city and district scales. Analyses consist of satellite image classification, plant index production, and GIS-based analyses methods. According to the results, it was determined that from 2004 to 2014, the 23.28% decrease in urban open-green spaces was detected in Nevsehir city. It was observed that the city expands towards the north-east, south-west, and west. It was indicated that there is a serious increase in built-up areas especially at the north-east part of the city (107.11%). Thus, a significant decrease has happened in the amount of urban open-green spaces in this area.
城市的物质形态由建成空间、开敞绿地和交通干线组成。城市化是一种动态过程，由上述各项因素以公平的比例构成，兼顾人类和自然。另一方面，由于城市人口的迅速增加，城市化在过去几十年已成为城市面临的一个严重问题，给城市开敞绿地带来压力。开敞绿地对于改善城市生活条件和平衡人类与环境之间被破坏的关系具有重要意义。因此，在规划研究中不能忽视城市开敞绿地的可持续性。本研究通过遥感（RS）和地理信息系统（GIS）的整合，在 10 年时间内（2004-2014 年）评估了土耳其内夫谢希尔的城市物质形态变化。通过使用具有高地面采样距离的卫星图像-QuickBird（60 厘米）（2004 年）和 WorldView-2（50 厘米）（2014 年）-详细检查了全市和区尺度的城市扩张方向以及城市开敞绿地和城市发展区发生的变化。分析包括卫星图像分类、植被指数生成和基于 GIS 的分析方法。结果表明，2004 年至 2014 年间，内夫谢希尔市的城市开敞绿地减少了 23.28%。观察到城市向东北、西南和西部扩展。表明建成区特别是城市东北部（107.11%）有明显增加。因此，该地区的城市开敞绿地面积显著减少。
