摘要

为应对全球气候变化与城市低碳转型需求，本文聚焦社区尺度碳排放的时变特征与多要素耦合效应，提出一种精细化计算方法。以广州市3个典型高密度住区为研究对象，通过构建建筑能耗动态模拟模型、交通出行统计模型及市政设施核算框架，结合逐时气象数据与实地调研参数以及碳排放因子法，量化计算了建筑、交通、市政等层面多要素耦合的碳排放量。结果表明，3个社区的建筑碳排放时变特性明显，居住建筑和商业建筑的碳排放高于其他类型建筑，且居住建筑碳排放量在建筑碳排放量中占比最高；交通碳排放中由汽油作为碳排放源驱动的交通碳排放占比高达76%，私家车则在所有交通出行方式中的碳排放量最大；市政设施碳排放中污水处理部分占比用水总碳排放达到了63%，垃圾处理碳排放中焚烧和填埋的碳排放量要远高于堆肥；道路照明碳排放中支路照明占比超过50%。此外，单位附属绿地的固碳量是4类绿地中最少的。综上，本文通过对社区尺度多要素碳排放的核算，明确了社区内空间结构、人口密度和建筑类型对碳排放影响和社区不同类型碳排放的现状。

Abstract

To address the challenges of global climate change and the imperative of urban low-carbon transformation

this study focused on the temporal characteristics and multi-factor coupling effects of community scale carbon emissions. A refined calculation method was proposed and applied to three typical high-density residential areas in Guangzhou. Based on dynamic simulation models for building energy consumption

transportation statistics

and municipal facility accounting frameworks

this study quantifies carbon emissions across buildings

transportation

and municipal services by integrating field survey parameters and carbon emission factors. The results revealed notable temporal variation in building carbon emissions

the residential and commercial buildings displayed higher emissions than other building types

with residential buildings accounting for the largest share of total emissions. Transportation emissions were primarily driven by gasoline-powered vehicles

constituting 76% of total transportation emissions

with private cars being the largest contributor. The wastewater treatment contributed 63% of carbon emissions from water use and the composting had the lowest carbon emission in waste treatment. In urban road lighting carbon emissions

branch road lighting exceeds 50%. Also

the carbon sequestration capacity per unit area of green space is lowest among all types. This study clarifies the impacts of spatial structure

population density

and building types on carbon emissions by accounting the multi-factor carbon emissions in community scale.
