摘要 ：
在分析北京市生态涵养区在生态补偿制度建设困境的基础上,本文将国内外区域生态系统价值评估模型相结合,运用修正的生态服务价值评估模型,对北京市生态涵养区2016年的生态服务价值进行了估算,并分析了2009—2016年生态服务价值的变动及其影响因素,从科学评估生态服务价值、完善生态补偿标准方法的制定、健全生态保护补偿制度、将绿色GDP纳入生态涵养区绩效考核指标评价体系几个方面探讨了完善生态补偿机制的政策措施.一方面更加直观地揭示了生态涵养区生态服务的重要经济价值,另一方面为建立更加科学的生态补偿机制提供了可参考的依据.

摘要 ：
The causes of frequent haze in Beijing-Tianjin-Hebei were truly complex, but the researches on the interrelation between haze and socio-economic factors were still lack of quantitative analysis. Considering that the interrelation under different regimes showed different change rules, the modified panel threshold regression model was applied to address different policy challenges. The results showed that the single threshold effect was significant while the added value of the tertiary industry or public transport was selected as the threshold variable. When the added value of the tertiary industry was less than the threshold value, the development of the secondary industry and the rising number of cars would increase PM2.5. Therefore, the expansion of the public transport would be an effective measure to ease the haze. When the added value of the tertiary industry exceeded the threshold value, the continued development of the secondary and the tertiary industry would reduce PM2.5, but the relief function achieved by expanding the public transport would be weakened slightly. Meanwhile the number of vehicles would become the primary factor influencing PM2.5. When the number of public transport was closer to its threshold value, the opportunity cost of PM2.5 reduction would be less and the increase of energy consumption would always increase PM2.5. As there were nonlinear relations between the haze and the socio-economic factors, the policy formulation of PM2.5-reduction should be combined with the threshold effect. © 2017, Editorial Board of China Environmental Science.

摘要 ：
At present, PM2.5 concentration in many provinces and cities in China are over the standard value, which is particularly serious in the regions with the leading level of economic development, such as Beijing-Tianjin-Hebei Region, Yangtze River Delta and Pearl River Delta. The sources of PM2.5 have attracted great attentions in all sectors of society. By analyzing the related literatures about different cities in different regions and combining with the latest source analysis results published by environmental protection administration, the PM2.5 source analysis in three key regions mentioned above is compared and discussed.The results show that among the three key areas, vehicle emission is the primary source of pollution in Beijing, Shanghai, Hangzhou, Guangzhou and Shenzhen. For second and third tier cities, PM2.5 sources are mainly coal-fired fly ash and dust pollution. Therefore, to reduce the pollution of PM2.5, reduction of the vehicle emission is the urgent task, which is also suggested to combine with the control of coal-fired fly ash and dust pollution. Finally, the further development directions of PM2.5 source analysis are proposed, which is expected to serve a reference for formulation of feasible policy measures to reduce the pollution of PM2.5. © 2017, China National Chemical Information Center.

摘要 ：
Low-carbon economy is a new development approach that is generated in the condition of the global climatic change and energy crises. Developing low-carbon economy and building low-carbon city are doable avenues on the premise of China's commitment to limit greenhouse gas emission. This paper studied the meaning of low-carbon development, constituted an overall merit index system and evaluation method, investigated an implemental approach of low-carbon, and proposed policy measures of developing low-carbon city.
