燃煤供热是北方城市采暖的主要方式，但煤燃烧过程中污染物的排放显著加剧了冬季大气污染状况，同时也增加了碳排放。在可持续、低碳发展的背景下，因地制宜发展清洁热源形式、选择合适的供热方式是城市供热规划的主要内容之一。探讨了包括集中燃煤供热、集中燃气供热、分布式燃气供热和分布式燃气——可再生能源联合等不同供热方式的原理、技术特点及优缺点，并综合比较其低碳、环境效益，从而为天津中心城区供热热源规划提供参考。
燃煤供熱是北方城市採暖的主要方式，但煤燃燒過程中汙染物的排放顯著加劇瞭鼕季大氣汙染狀況，同時也增加瞭碳排放。在可持續、低碳髮展的揹景下，因地製宜髮展清潔熱源形式、選擇閤適的供熱方式是城市供熱規劃的主要內容之一。探討瞭包括集中燃煤供熱、集中燃氣供熱、分佈式燃氣供熱和分佈式燃氣——可再生能源聯閤等不同供熱方式的原理、技術特點及優缺點，併綜閤比較其低碳、環境效益，從而為天津中心城區供熱熱源規劃提供參攷。

In north China,coal heating is a major way of urban heating in winter.However,pollutants discharged during the heating process have significantly aggravated atmospheric contamination in the season while increasing carbon emissions.Under the background of sustainable and low-carbon development,one of the important contents of urban heat supply planning is to choose an appropriate heating mode and to develop clean heat source according to local condi-tions.This paper discusses the principle,technical feature and advantages and disadvantages of various heating modes, such as intensive (coal) heating,intensive (gas) heating,distributed (gas) heating and distributed (gas)-renewable energy sources.Besides,it makes a comprehensive comparison between their low-carbon degrees and environmental benefitsso as to provide reference to heating source program in central urban areas of Tianjin.
