| 摘 要： | 摘 要：综合分析了西安市负积温、供暖初日、供暖终日、供暖期天数以及西安集中供暖面积和供暖热消耗量的多年变化。结果表明：在全球变暖的背景下，西安市亦存在冬季越来越暖，采暖期越来越短的趋势；随着经济的发展，集中供暖总面积和总供暖热消耗量不断增加，而单位供暖面积的热消耗量的总趋势随年代有所减少，但逐年耗热量与冬季气温的相关性并不好，说明实际供暖部门并没有根据气候变化调整能源投入。因此，建议冬季供暖的初、终日期及供暖强度应随着天气冷暖变化而随时调整，实现合理节能。

| Abstract: | The negative accumulated temperature, the first heating date, the last heating date, heating duration, collective heating area and energy consumption for winter heating in Xi'an during 1986-2002 were comprehensively analyzed. The results show that under the global warming, winter in Xi'an became warmer and warmer and heating duration shorter and shorter. With the development of economy, the area and energy consumption for collective heatingincreasedcontinuously;and inthe meantime,the energyconsumptionper unitarea forwinter heatingdecreasesd year by year, but it didn't match the winter temperature well because the energy was not proportionally consumed according to the change of temperature. In order to conserve energy effectively, heating in winter should be timely adjusted according to actual temperature change. |
