黑色产业的绿色发展之路

实现煤炭的清洁高效利用,关键是提高电气化率,但前提是技术突破。煤炭清洁化的技术路径对企业的技术能力和经济实力提出了挑战,必须进行深层次的调整,从根本上理顺政府与企业的关系,各司其职,使政府退出对市场主体的直接干预,转变角色为行业管理者和环境监管者,激励企业承担相应的环境责任,通过市场机制淘汰落后产能,最终实现黑色产业的绿色发展之路。     

完全恢复臭氧层至少要近百年——访臭氧层保护研究专家、北京大学环境科学与工程学院教授胡建信

正今年9月16日,是第20个国际臭氧层保护日。在国内对这个重要环境日的反应几乎是悄无声息的气氛中,本刊记者采访了我国臭氧层保护研究专家,北京大学环境科学与工程学院教授胡建信。胡建信是国内最早一批参与臭氧层保护研究的专家。自1990年代初以来,他先后参与了由国务院发布的《中国逐步淘汰消耗臭氧层物质国家方案》     

空调设备节能降耗的途径

编者按 电力革命的产物--空调是人们益寿延年的功臣之一.空调设备在创造局部环境舒适的同时,既消耗了大量的能源,又在破坏臭氧层,加剧温室效应.

通过对福建省机械厂生产的ＷＺ２５－２０型液压挖掘装载机噪声源进行识别及降噪途径分析，利用精密声级计和动态分析仪等仪器进行噪声测试和信号分析，找到了该机器的主噪声源，提出了降低该机器噪声的措施。     

No Sustainability without Technical, Fiscal and Social Innovation

Officially, the environmental protection from industrial insults began with Rachel Carson＇s book ＂The Silent Spring＂ in 1963. Protection priorities have since changed. They can be grouped into three successive phases.     

论破坏环境资源保护罪相关民事公益诉讼的提起

破坏环境资源保护罪必然会造成环境公共利益的严重受损,需要通过附带或另行提起相关环境民事公益诉讼来弥补给生态环境带来的损害。文章分析了对破坏环境资源保护罪提起相关环境民事公益诉讼的必然性,并基于谦抑性、程序效益和程序安定性等诉讼价值的考虑,指出不同主体在起诉顺位上应遵循社会组织优先、行政机关次之、检察机关最后的规则。同时分析了对本类罪名附带提起民事诉讼的在级别管辖和诉前公告程序等方面的特别规定,提出对应策略建议。     

Comparison of temporal and Spatial Characteristics of Ozone Pollution at Ground Level in the Eastern China

Monitoring data from ozone（O3） automatic stations in three typical cities with different climatic areas in the southern and northern parts of eastern China are used to analyze temporal and spatial characteristics of ozone pollution at ground level. The results show that ozone pollution level has distinct regional differences and the concentration in the suburbs is higher than that in the urban areas. The seasonal variation of ozone concentration in different climatic areas is greatly affected by the variation of precipitation. Ozone concentration in Shenyang and Beijing , in the temperate zone, has one perennial peak concentration, occurring in early summer, May or June. Ozone concentration in Guangzhou, in sub-tropical zone, has two peak values year round. The highest values occur in October and the secondary high value in June. The ozone season in the south is longer than that in the north. The annual average daily peak value of ozone concentrations in different climates usually occur around 3 pm. The diurnal variation range of ozone concentration declines with the increase of latitude. Ozone concentration does not elevate with the increase of traffic flow. Ozone concentration in Guangzhou has a distinct reverse relation to CO and NOx. This complicated non-linearity indicates that the equilibrium of ozone photochemical reaction has regional differences. Exceeding the rate of Beijing＇s lh ozone concentration is higher than that of Guangzhou, whereas the average 8h ozone level is lower than that of Guangzhou, indicating that areas in low latitude are more easily affected by moderate ozone concentrations and longer exposure. Thus, China should work out standards for 8h ozone concentration.
