摘　　要：为解决越来越大的城市燃气峰谷差,通过对各类调峰方式进行对比分析,提出了可采用建设LNG调峰储备站对城市燃气进行季节调峰和应急储备的对策。投资测算表明,大型城市燃气公司可建设LNG调峰储备站,中小城市燃气公司可建设LNG卫星站来储备LNG用于调峰和事故应急。因购买LNG与天然气形成的价差,近期可利用CNG价调基金,中远期可以调峰气价的方式解决。并以川渝地区为例分析了建设LNG调峰储备站对区域经济的影响,结果表明:建设LNG调峰储备站是可行的,冬春季时用LNG进行调峰可使原来要减停用气的行业正常运行,不仅保障了实体经济平稳运行,也完善了LNG产业链,使《城镇燃气管理条例》的相关规定落到实处。最后,建议政府在建设LNG调峰储备站方面要发挥主导作用:①合理规划、布局LNG产业链;②强制要求较大的城市燃气公司建立LNG调峰储备站;③制定建设LNG调峰储备站的优惠和鼓励政策;④制定各级城市燃气公司的标准储备量;⑤研究择机推行调峰气价和居民阶梯气价。In view of the expanding peak-valley gap in an urban gas supply system, this paper made a comparative analysis of all types of peak-shaving methods and proposed a strategy of adopting the way of LNG stations as peak-shaving and emergency reserves. The cost premium showed that LNG stations with storage tanks should be appropriate for big cities while small LNG gasification sta tions, the so-called LNG satellite stations, for the small and medium-sized cities. Due to the price difference between the purchased LNG and natural gas, the CNG price adjustment fund will be taken advantage of in the short run but the way of peak shaving gas price will be in the mid-long run. In a case study in Sichuan and Chongqing areas, this paper analyzes the impact of LNG storage sta- tions on the regional economy. It was found that the proposed strategy of LNG storage stations is feasible, and especially in spring and winter times, gives a slim chance of survival for the fuel gas eutting industries in the past. In this way, not only is the substantial economy maintained steady, but the LNG industrial chain is fulfilled and The Regulation and Administration of Urban Gas will be implemented. In the end, this paper suggests that the government should play a dominant role in encouraging and stimulating the construction of LNG storage stations in the following aspects： to make a reasonable scheme and layout of the LNG industrial chain; to compulsively com- mand those fuel gas companies in big cities to construct LNG storage stations; to formulate preferential and encouragement policies on the projects of LNG storage stations; to stipulate the standard reserves volume for the fuel gas companies in the city at all levels; and to study the proper time to put into force the gas price at peak-shaving times or gas price ladder for residents.
