In recent decades, urbanization has become a significant urban environmental and ecological concern, especially in most developing countries. In China, rapid urban sprawl has had a profound influence on runoff and results in larger and more frequent incidents of flooding in many urban areas. Therefore, evaluating the impacts of urbanization on runoff is of great important for urban planning pol...

Land cover/land use categories are relevant components in land management. Understanding how land cover/land use change over time is necessary to assess the consequences of humans and natural stressors on the earth’s environment and resources. The aim of the study was to map and monitor the spatial and temporal change in land cover/land use for the periods of 1977, 1991 and 2016 and to predict ...

Rapid urbanization, land scarcity, and accompanying ecological deterioration in China have received growing attention. In this paper, two fast-growing metropolitan regions, Greater Shanghai and Greater Hangzhou, were selected as case studies to quantify the impact of land use/land cover (LULC) change on regional ecosystem services value (ESV) at the landscape scale since the late 1970s. The res...

The objective of this study was to analyze land use/land cover (LULC) changes in the landscape of Munessa-Shashemene area of the Ethiopian highlands over a period of 39 years (1973–2012). Satellite images of Landsat MSS (1973), TM (1986), ETM+ (2000), and RapidEye (2012) were used. All images were classified using object-based image classification technique. Accuracy assessments were conducted ...

This study proposes an integrated modeling system consisting of the physically-based MIKE SHE/MIKE 11 model, a cellular automata model, and general circulation models (GCMs) scenarios to investigate the independent and combined effects of future climate and land-use/land-cover (LULC) changes on the hydrology of a river system. The integrated modelling system is applied to the Elbow River waters...

Comparison between two maps of land use/land cover (LULC) is a fundamental task in remote sensing and geospatial data analysis with application to change detection, validation of models, and accuracy assessment [1, 2]. We present a methodology of calculating a similarity measure between every pair of LULC maps in a collection in order to classify them into characteristic LULC patterns. A patter...

introduction land use and land cover change (lucc) is a complex issue resulted from biophysical, socio-economic, cultural, organizational and technological factors in different spatial and temporal scales. lucc considered as an important threat to biodiversity as causing the fragmentation, natural vegetation destruction and natural areas isolation the regions which managed by environmental prot...

urban growth and associated landscape transformation has been a major driver of local, regionaland global environmental change. the conversion of urban greenery to impervious landscapes has been identifiedas a key factor influencing the distinctive urban heat and associated consequences. due to the often highdemand for space in urban areas, creation and preservation of urban greenery as heat si...

Land use and land cover (LULC) datasets for Beijing in 1978, 1987, 1992, 2000 and 2010 were developed from Landsat images using the object-oriented classification approach. The relationships between social-economic, demographic and political factors and time-series LULC data were examined for the periods between 1978 and 2010. The results showed the effectiveness of using the object-oriented de...

Land use/land cover (LULC) change is one of the most important indicators in understanding the interactions between humans and the environment. Traditionally, when LULC maps are produced yearly, most existing remote-sensing methods have to collect ground reference data annually, as the classifiers have to be trained individually in each corresponding year. This study presented a novel strategy ...
