| 1 | 一种新的增强型不透水面指数显示文摘针对西北干旱地区城市不透水面提取存在的局限性以及阈值确定的繁琐性等问题,该文提出了一种新的增强型不透水面指数(ENDISI)。基于Landsat8_OLI影像,以兰州市建成区为例进行不透水面信息提取,总体精度达到88.5%,结果较为理想。相比于已有的不透水面指数,ENDISI可以有效避免西北干旱区沙土、裸露山体的影响,适用性更强;采用'0'作为提取不透水面的阈值,简单、客观并且提取精度高。综上表明,ENDISI可用于西北干旱地区城市不透水面信息的高效提取。 | 穆亚超 颉耀文 张玲玲 陈云海 | 2018 | 测绘科学2018，43，2： | 23 |
| 2 | Using Impervious Surfaces to Detect Urban Expansion in Beijing of China in 2000s显示文摘The change of impervious surface area(ISA) can effectively reveal the gradual process of urbanization and act as a key index for monitoring urban expansion. Experiencing rapid growth of the built environment in the 2000 s, urban expansion of Beijing has not been fully characterized through ISA. In this study, Landsat TM images of Beijing in 2001 and 2009 were obtained, and the eight-year urban expansion process in Beijing was analyzed using the ISA extracted by means of the vegetation-imperious surface-soil(V-I-S) model. From the spatial variation in ISA, the ring structure of urban expansion in Beijing was significant during the study period, with decreasing urban density from the city center to the periphery. In the ring road analysis, the most dramatic changes of ISA were found between the fifth ring and the sixth ring. This area has experienced the most new residential development, and is currently the main source of urban expansion. The typical profile lines revealed the directional characteristics of urban expansion. The east-west profile was the most urbanized axes in Beijing, while ISA change in the east-north profile was more significant than in the other five profiles. Moreover, the transition matrix of ISA levels revealed an increase in urban density in the low density built areas; the Moran′s I index showed a clear expansion of the central urban area, which spread contiguously; and the standard deviational ellipse indicated the northeast was the dominant direction of urban expansion. These findings can provide important spatial control guidelines in the next round of national economic and social development planning, overall urban and rural planning, and land use planning. | PENG Jian LIU Yanxu SHEN Hong XIE Pan HU Xiaoxu WANG Yanglin | 2016 | Chinese Geographical Science2016，26，2： | 11 |
| 3 | 徐州市中心城区不透水面时空异质性分析显示文摘不透水面是影响区域空间规划和生态建设的重要因素,可以有效反映城市发展变化。徐州市作为淮海经济区中心城市,经历了快速城市化阶段并向生态园林城市转型,刻画其城市不透水面变化具有典型意义。通过比较4个光谱指数(不透水面指数ISA、城市建成区指数BUAI、生物物理成分指数BCI、增强型归一化差值不透水面指数ENDISI)以确定不透水面信息提取的最佳指数;引入分形理论和景观生态学方法,从行政区、剖面线、景观格局指数多方面分析徐州市中心城区(包括8个片区)不透水面2000、2007和2017年3个时期的时空异质性,旨在揭示其在城市化背景下的时空演变规律,为城市未来发展提出建议。结果表明:(1)BUAI提取研究区不透水面的精度最高(Kappa系数=0.81),远高于其他3个指数,可有效提取多时相不透水面信息;(2)各个片区的不透水面存在差异,老城片区(商业金融中心)和金山桥片区(经济技术开发区)的不透水面比例一直较高;BUAI剖面线揭示了城市扩张的方向特征,研究区的不透水面向东和向东南方向有所发展;(3)研究区不透水面景观格局呈破碎化趋势,由填充式增长转变为分散式扩张,不透水面景观形态趋向复杂化和不规则化,景观格局的异质性增强。该研究可以为城市未来发展和土地利用规划提供科学依据。 | 李涵 李龙 张婷 陈龙乾 | 2019 | 长江流域资源与环境2019，28，3： | 11 |
| 4 | Urban Expansion in China Based on Remote Sensing Technology:A Review显示文摘Urban areas and its evolution are important anthropogenic indicators and human ecological footprints, and play decisive roles in environmental change analysis, global geo-conditional monitoring, and sustainable development. China has the highest rate of urban expansion and has emerged as an urban expansion hotspot worldwide. In this paper, the progress of studies on Chinese urban expansion based on remote sensing technology are summarized and analyzed from the aspects of urban area definition, remotely sensed imagery applied in urban expansion, monitoring methods of urban expansion, and urban expansion applications. Existing issues and future directions of Chinese urban expansion are discussed and proposed. Results indicate that: 1) The fusion of multi-source remotely sensed imagery is imperative to meet the needs of urban expansion with various monitoring terms and frequencies on different scales and dimensions. 2) To guarantee the classification accuracy and efficiency and describe urban expansion and its influences on local land use simultaneously, the combination of visual interpretation and automatic classification is the tendency of future monitoring methods of urban areas. 3) Urban expansion data have become the prerequisite for recognizing the urban development process, excavating its driving forces, simulating and predicting the future development directions, and also is conducive to revealing and explaining urban ecological and environmental issues. 4) In the past decades, Chinese scholars have promoted the application of remote sensing technology in the urban expansion field, with data construction, methods and models developing from the quotation stage to improvement and innovation stage; however, an independent and consistent urban expansion data on the national scale with long-term and high-frequency(such as annual monitoring) monitoring is still lacking. | ZHANG Zengxiang LIU Fang ZHAO Xiaoli WANG Xiao SHI Lifeng XU Jinyong YU Sisi WEN Qingke ZUO Lijun YI Ling HU Shunguang LIU Bin | 2018 | Chinese Geographical Science2018，28，5： | 6 |
| 5 | 基于光谱混合分析方法的城市扩张过程研究显示文摘利用光谱混合分析(SMA)方法研究沈阳市1992-2007年间城市扩张过程,选择1992、2001、2007年各一景Landsat TM/ETM+遥感影像,基于SMA模型获得不同年份城市不透水面(ISA,Imperious surface area)分布,将城市空间划分为四个方向(西北、东北、西南、东南),利用不同年份ISA差值结果分析城市扩张过程。研究结果表明,在城市扩张过程中低值ISAchange面积大于高值ISAchange面积,即城市发展是一个渐进的过程。1992-2001年间,沈阳市城市扩张主要向西北、东北和西南方向;2001-2007年间,沈阳市城市扩张主要向东北和西南方向;1992-2007年间,沈阳市整体上向西北、东北和西南方向扩张,东南方向扩张较小。随着社会的发展,沈阳市城市化进程不断加快。 | 李富祥 李雪铭 李华朋 | 2010 | 城市发展研究2010，17，10： | 5 |
