Increasing greening has been occurring for land use and land cover of fast urbanization areas is surprising. This paper introduce a new method for greening trend analyzing based on the results of a newly developed algorithm called CCDC (Continuous Change Detection and Classification). This method is capable of separating change caused by abrupt and gradual changes, and providing information on the...
For a long time, global environmental change has become a focus all over the world. Environmental change not only alters the local natural landscape, but also will long impact the local or even large-scale ecosystem. While, the primary manifestation of environmental change is the land use/land cover change. In this study, taking Mentougou district in the west of Beijing for example, the temporal and...
Space borne imaging spectrometry provides spectral information which can be used to extract parameters of interest in monitoring regional environmental remediation initiatives. The environment surrounding the City of Greater Sudbury in Ontario Canada has been affected by deposition of sulphur-dioxide and metals from a century of smelting operations. Impacts have been noted up to 100 km downwind of...
In order to evaluate the impact of urbanization on carbon cycle, we selected the Beijing city as the study area to estimate CO2 emission both from anthropogenic activity and natural processes. The spatial pattern of annual CO2 emission in 1992 and 2005 in Beijing city was estimated by using the socio-economic statistical data, remote sensing data and GIS-based approach. The main factors include transport,...
