Eco-culture is essentially a social ideology which promotes coexistence and mutual prosperity between mankind and nature, in order to realize cohesive and harmonious development of ecology, economy and society. Based on the analysis of essence of eco-culture, this paper reveals a mechanism that eco-culture influenced on urban development and analyzes its phenomena. We find that eco-culture is the driving force and soul of urban ecological development, which has penetrated into every aspect of urban society, economy, planning and construction. Eco-culture can not only contribute to resolve ecological crisis, but also facilitate the resource-saving and environment-friendly society development, also promotes the circular economy development, and plays an important role in constructing ecological physical space. © 2014 L & H Scientific Publishing, LLC.

Carbon emission from municipal solid waste (MSW) treatment is one of the anthropogenic sources to cause climate change, which accounts for 3-5% of global greenhouse gas emissions according to the report of the United Nations Environment Programme (UNEP). At the same time, the gases and liquid discharged from MSW treatment can also cause other environmental impacts, such as climate change, photochemical ozone synthesis, and acidification, especially in huge city with huge population as Beijing, China. This paper proposed an eco-efficiency analysis method, which aimed to yield maximum overall environmental improvement per unit investment cost during its life cycle processing. This method took the overall reduction in the environmental impact of MSW treatment using cost-effective techniques as the objective to optimize waste disposal systems. The separation ratio during MSW collection and the proportion of techniques used for treatment were the major indicators for optimization measures. For Beijing, an increase in the waste separation ratio during collection proved to be the most effective measure, with an eco-efficiency score of 0.144. Adjustment of the proportion of treatment techniques used was less eco-efficient, with an increase in the proportion of composting being the most effective approach. Based on real needs, the objective should be to reduce the proportion of landfills used and increase the amount of composting and incineration. This optimization measure had the lowest cost and an eco-efficiency score of 0.0461, which is 60% higher than that for the measure with the lowest eco-efficiency. © 2014 Elsevier Ltd.

The unsignalized crosswalks are the weakness tache of road traffic safety, and are easily to cause traffic accidents, in urban transportation systems consisting of the human and vehicle, roads and the environment, management and other elements. With the camera and video detector, the information of pedestrians in the typical unsignalized crosswalks in Chongqing is obtained. And the pedestrian crossing speed characteristics of the individual and crowd, different age groups and different sexes are analyzed by the SPSS(SolutionsStatistical Package for the Social Sciences). Results show that the speed through different lanes are various, and the speed of the elderly is minimum. Finally basic design principles to traffic signals and traffic facilities of unsignalized crosswalks of mountainous city are proposed. © 2011 IEEE.
