【摘要】 提出一种适用于城市规划阶段的基于分类用地单位面积年用气量指标的年用气量计算方法。分类用地一定面积年用气量计算方法是以城市用地类型为基础，根据用地面积和分类用地单位面积年用气量指标进行用气量计算。推导得出分类用地单位面积年用气量指标的计算方法。研究得到广州市居民用地单位面积年用气量指标为1.96～3.92 m~3/（m~2·a）,公建商业用地单位面积年用气量指标为0.29～8.40 m~3/（m~2·a）,工业用地单位面积年用气量指标为0.11～4.20 m~3/（m~2·a）。更多还原

【Abstract】 A method for estimating annual gas consumption based on unit-area annual gas consumption indicators for classified land use is proposed,suitable for the urban planning stage. This approach calculates gas demand by integrating land area with corresponding annual gas consumption indicators specific to each urban land use category. A method for calculating the unit-area annual gas consumption indicator is derived. The study shows that in Guangzhou,the unit-area annual gas consumption indicator ranges from 1.96 to 3.92 m~3/（m~2·a） for residential land use,from 0.29 to 8.40 m~3/（m~2·a） for public and commercial land use,and from 0.11 to 4.20 m~3/（m~2·a） for industrial land use.更多还原
