Abstract: Haze pollution might have a great effect on a destination’s image and might make the entire tourism industry fall into decay. In China, particularly in Beijing, pollution is extremely serious. Based on a study of Beijing using questionnaires for potential tourists, perceived health risks, perceived impacts on the tourism experience, and attitudes about the impacts of haze were explored. The results indicate that haze pollution has a considerable perceived impact on travel, and there are obvious differences among travel contents/elements and even tourism market segments. Due to its perceived impacts, haze pollution will be taken into account in tourists’ decision-making processes, causing a portion of potential tourists to cancel tourism plans.

Abstract: An economic-environment model is used to analyze economic and environmental impact of reclaimed water utilization in Beijing. The simulation results predict the potential of 130 thousand tons T-N can be reduced for the utilization of reclaimed water by keeping GRP growth rate at 8%. 5 billion tons reclaimed water can be produced by construction of new sewage plants. The utilization of reclaimed water can alleviate water shortage and pollution in Beijing.

Abstract: A spatial and temporal distribution of PM_2.5 as one of the most critical pollutants in Beijing was studied for the whole year 2013. In this pre-research work the spatiotemporal variation of PM2.5 in studied over metropolitan area of Beijing in 2013. More over a weighted transportation influence ( WIT) is defined to monitor the role of transportation in PM2.5 pollution. The results show the remarkable effect of transportation in PM2.5 concentration (R²=0.75). Plus, with this research, we give more information about the source of high PM_2.5 concentration in Beijing, and suggest to control this matter transportation is one of the notable source which requires more attention from decision makers.

Abstract: On 21 July 2012, a huge thunderstorm hit Beijing, prompting the city government to act immediately to deal with the emergency. Yet great losses were caused, exposing problems about urban flood control and drainage, and making people take a new look at them. It is not uncommon for a rainfall of such a degree to happen in Asia. Comparatively speaking, however, unlike in Beijing, fewer damages are caused in Taiwan, Japan and the Philippines given the same situation. In this article, therefore, the problems arising after a heavy rainfall and their solutions will be discussed.

Abstract: The traffic flow, existing signal timing, lane arrangement and other field survey data were analyzed and computed in the paper first. Next, the traffic capacity and service level of Weigong village intersection were evaluated. Finally, Using Webster method to calculate the related data of signal timing, and Vissim are used to simulate the traffic conditions of the intersection. The result of simulation indicated that the optimized traffic control scheme reached the goal improving the operational condition of Weigong village intersection and unobstructed degree of road.

Abstract: Traffic noise is a major source of noise pollution in the urban environment, including road traffic noise and rail traffic noise, which has become one of the domestic large and medium cities in environmental issues to be solved. This paper analyzes the status of the Beijing traffic noise pollution and control strategies, and a typical apartment block selected as a case, analyzes its noise pollution elements, severity, time distribution, and draws a noise map of the plane area and a dormitory building in the noise conditions typical time. Last we discussed and gave the method based on noise control measures.

Abstract: A detailed study was conducted to determine the current statues of the heavy metals in roadside dusts collected from universities in Beijing, China. Twelve universities were selected and analyzed to determine the occurrence, distribution, and assessment of heavy metals in roadside dusts. The results showed that Cr, Cu, Zn, Cd and Pb exhibited higher metal concentrations than the local soil background values, indicating that the pollution may come from anthropogenic input. The assessment by Geoaccumulation Index (I_geo) indicates that Cr and Ni are at the unpolluted level, Cu and Zn at the slightly polluted level, Cd and Pb at the moderately contaminated. The pollution level was in the following order: Cd > Pb > Zn > Cu > Cr > Ni.

Abstract: The purpose of this paper is to construct a dynamic comprehensive optimization simulation model to forecast the net load of water pollutant and economic growth rate of Beijing. Our results propose an optimal policy for helping to achieve the goal of sustainable development. We performed a linear optimization modeling by using LINGO software to simulate a socio-economic model and an environmental model with input-output table. The socio-economic model represents the relationship between socio-economic activities and water pollutant emissions. The environmental model represents the changes in the amount of water pollutants generated.
