2、d Outcome 六、经费预算 Budgets,一、研究背景 Background,城市是人类政治、经济和文化活动的中心。改革开放以来，我国的城市建设得到快速发展，城市数量已达到660多座，城市化率由不足20%增长到41.7%。 Chinese cities expended significantly.2004年监测的342个城市中，仅有132个城市达到国家环境空气质量二级标准（居住区标准），占38.6%。 In 2004, the urban air quality of 38.6% of the monitored cities (342 cities) could meet the

3、second national standard of ambient air quality.,温室气体的排放是空气污染的一个重要方面，它可以导致全球气候变化，从而人类的产生不良影响。 Greenhouse gas emission is one of the important aspects of air pollution in the world. 我国政府高度重视城市空气质量问题的重要性和严重性，采取了积极的控制措施，包括：改善能源结构、污染源外迁、重点污染源末端治理、热电联产等。 Chinese government has been paying a lot of attent

7、ting rule-of-thumb prevailingInsufficient retrospective assessment on various strategies to address air pollution Co-benefits of GHG emissions reduction unaccounted from amelioration of air quality (act locally but dont think globally),大多数地方城市根据自身特点采取了空气污染治理措施，其中一些城市已 经应用了城市空气质量模式和预报模式 ，如：用于大气污染物问题控

8、制 的箱模式、工业源复合模式、光化学模式和线源模式等。 这些模式多是 基于国外城市的大气质量监测基础数据和预测工作经验建立起来的，而 我国许多城市的自然条件及污染特征与模式原出国城市都可能存在较大 的差异。 Most cities has taken relevant control measures to solve the urban air pollution, and some of them have used the urban air quality model and prediction model, such as box model, industrial source

9、complex model, photochemical model and line source model, and so on. Most of such models were set up based on the air quality data and prediction experiences of overseas cities, and the natural conditions and pollution characters of many Chinese cities are different from those cities where the model

10、s applied in. For example, urban air pollution of developed countries mainly from vehicle emission, but most urban air pollution in China is attributed to the coal burning, or the mixing pollution of coal burning and vehicle emission.,各种减排方案分析研究，成本-效能分析开展的还不够充分。没有适当的方法可以将空气污染造成的所有损失费用和控制空气污染物所需的费用进行

11、量化，并通过比较选择出一项或多项污染损失和控制费用之和最小的污染控制方案为实施方案。 The study and analysis of emission reduction and cost-efficiency program has not been completed in China. 实施的多种空气质量控制措施必定可以削减温室气体的排放量，但尚未进行定量的研究 (many countermeasures to address urban air pollution simultaneously bring GHG emission reduction, but barely hav
