Halon与环境保护

一、Halong为何物,它的命名和用途。 Halong是什么?Halong(哈龙)是消防灭火剂的代名词,就如Freon(氟里昂)是工业致冷剂的代名词一样。Halong是英语Halongenated hydrocarbor(卤代烃)的简写。美国消防词典上说:Halong,是一个人为编出来的普通代号,它代表几种卤代烃,其中这三种CCl_4(四氯化碳),CH_2CIBr(一氯溴甲烷,Halong1011),CF_3Br(三氯溴甲烷,Halong 1301)作为灭火剂效果最好。Halong1211(CF_2CIBr三氟氯溴甲烷),1202

生态型港口综合评价指标体系初探

基于上海市建设生态型城市的长期目标，将港口作为城市生态系统中重要的子系统，对如何建设生态型港口提出了综合评价指标体系。通过筛选得到45项单因素指标，针对不同类型的港区有所分异，整个评价体系分为5个准则层（生态环境、经济效率、污染控制、环境管理、社会评价）和10个因素层（大气/声环境、生物资源、基底质量、经济发展、生产效率、循环经济、污染排放、清洁生产、环保投入、社会参与），并采用AHP（层次分析）法确定了各层次的权重分配。进而根据2005年上海港年均生产状况和2006年上半年的港区环境－资源调查，尝试对上海港7种主要类型（集装箱、件杂货/成品、多用途、干散、粮食港区、液散、客运）的15个港区进行了现状评估。然而，生态港评价系统的指标选取、权重制定、评估级别等实践与完善仍需要多学科和政府职能部门的参与。最后，项目还提出了水生态健康、航道淤积、生态风险、水陆景观等非定量生态港评价因子。     

On Index System and Quantitative Assessment of Eco-cities： A Case Study on Urban Agglomeration of the Yangtze Delta

Urban agglomeration of the Yangtze Delta （UAYD）, one of the most developed regions of China, has witnessed an increasing prevalence in building ecological cities when the ecological cities are pursued by many modem cities, and great achievements have been made in this regard. It is inevitable, however, that certain problems exist during the construction of ecological city, which include but not limited to non-harmonious development of urban complex ecosystem, and the difficulty in quantifying eco-city construction or incomplete quantification in assessing the construction of present and future eco-city. Based on the analysis on social-economic conditions and regional conditions of the UAYD, this paper attempts to set up an index system of eco-cities combining with local characteristics, and to adopt the indices of eco-city, urban harmony, and eco-city colligate to evaluate the ecological level, urban harmonious development and eco-city construction of cities within the UAYD. Results indicate that among 15 cities in UAYD, Suzhou City ranks the highest in terms of eco-city construction, whereas Nantong ranks relatively lower; sustainable eco-city construction is possible only when cities are developed in every respect of harmony.
