Sudden events of crisis (‘focusing events’) trigger intense media reporting, which in turn can prompt political decision‐makers to respond with an adjustment of existing policies. As such, focusing events can potentially lead to long‐term policy change on a certain issue. This article explores the sudden and intense period of air pollution in Beijing in January 2013 as a focusing event. The episode,...
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...
The eco-environmental regionalization is a comprehensive division process based on the geographical differences of regional eco-environment status. Compared to the traditional method, spatial analysis is more and more used to get the main characteristic of the eco-environment before regionalization. In this paper, TM, SPOT and QuickBird images of 2000-2008 are taken as data sources. And using Remote...
This paper presents a novel method for quantification of the total emission of gases from area sources using the mobile mini-DOAS (Differential Optical Absorption Spectroscopy) instrument, a ground based optical remote sensing technique. The presented method has been applied to measure the emission of SO 2 and NO 2 from the city of Beijing, P.R. China, on a time scale of approximately...
There are many uncertainties regarding the future level of natural gas consumption in China. In order to obtain a clear idea of what factors drive fuel consumption choices, we focus on three regions of China: Beijing, Guangdong, and Shanghai. Using an economic optimization model (MARKAL), we consider drivers including the level of sulfur dioxide emissions constraints set by the government, the cost...
