Sand and dust storms (SDS) are common phenomena in arid and semi-arid areas. In recent years, SDS frequencies and intensities have increased significantly in Iran. A research on SDS sources is important for understanding the mechanisms of dust generation and assessing its socio-economic and environmental impacts. In this paper, we developed a new a...

The Greater Mekong Subregion (GMS) has experienced rapid economic growth and urbanization. However, few studies have paid attention to urban land use dynamics, especially spatiotemporal patterns of urban expansion and land use change, in this region. This research aimed to conduct a comprehensive study of urban land use change in Xishuangbanna, Yan...

Sand and dust storms (SDS) are global phenomena that significantly impact the socio-economy, human health, and the environment. The characterization of SDS intensity is a fundamental aspect of SDS issues and studies. In this study, a sand and dust storms index (SDSI) is developed to characterize SDS intensity by addressing the potential impacts of...

Since the Chinese government carried out the reform and opening up policy, Xishuangbanna Dai Autonomous Prefecture has experienced rapid urbanization and dramatic land use change. This research aims at analyzing urban expansion in Xishuangbanna and its impact on the land use pattern using combined methods, including radar graph, the gradient-direct...

Exploring the relationship between the economy and the ecosystems in China could not only be beneficial for achieving the harmonious coexistence between humans and nature but also offer scientific references for the international society. This study aimed to elucidate the long-term ecological–economic relationship in China from the symbiotic perspe...

Understanding the evolution of the rural-urban interface (RUI) and its dynamic ecological consequences is of great theoretical and practical significance for urban-rural integration and management. In this study, Nanjing is taken as an example, and the evolution of the RUI in 1990, 2000, 2010, and 2020 and its effects on the ecological landscape st...

As a type of urban gentrification oriented by high-quality educational resources, jiaoyufication is a socio-spatial process that refers to the middle-class group that attaches importance to education realizes the agglomeration in famous school districts by purchasing high-price school district houses. Based on the theoretical analysis of jiaoyufica...

The continuous development of agricultural technologies and produces trade and updated state reforms strongly shape the dominant organizing styles of local agriculture production. Since the end of the 1970s, rural China has witnessed a drastic agriculture transformation featured by de-collectivization, and recently in Taicang, a developed city in t...

Identification of urban growth patterns is essential to better understand urbanization and its eco-environmental consequences. Landscape indices, such as the simple urban growth index (S) and the landscape expansion index (LEI), are commonly used to identify urban growth patterns, but most of them are unable or not robust enough to recognize multi-...

Well-functioning ecological corridors are critical for conserving biodiversity in areas undergoing increasing habitat losses and ecosystem fragmentation. Although it is essential to rebuild broken corridors by land use adjustments, related discussions of spatially explicit delineations of to-be-adjusted lands and quantitative adjustment costs are r...

With their significance in connecting socio-economic development and related eco-environmental consequences, land use transitions have gradually become the focus of land change science and sustainability science. Although various research studies have determined the ecological effects of land use transitions and provided suggestions to regulate the...

Urban spatial expansion (USE) is an uneven process affected by both natural and human factors, and land use regulation policy is of significance. To indicate the potential effects of different policies at a regional scale and then improving them under the context of increasing emphasis on land protection, we take Southern Jiangsu Urban Agglomeratio...

Aiming at assessing the ecological stress of land urbanization comprehensively, three perspectives are considered and combined, i.e. the amount effect with the proportion of construction lands as the indicator, the intensity effect per the density of environmental pollutant emissions, and the location effect based on their spatial distribution in t...

Google Earth (GE), a large Earth-observation data-based geographical information computer application, is an intuitive three-dimensional virtual globe. It enables archaeologists around the world to communicate and share their multisource data and research findings. Different from traditional geographical information systems (GIS), GE is free and ea...

This study mainly focuses on revealing an ancient water landscape at the Longcheng site in the northern Chaohu Lake Basin using very high-resolution (VHR) GeoEye-1 imagery. First, prior to classification, the GeoEye-1 image was processed following atmospheric and geometric correction. The supervised classification was carried out in order to show t...
