摘要
CH_(4)是仅次于CO的重要温室气体,准确估算CH_(4)排放量对实现碳达峰、碳中和有着重要意义。自下而上方法可用于估算CH_(4)排放量,结合GIS技术可改善CH_(4)排放量的估算结果,使其更加科学合理。文章以估算CH_(4)排放量的自下而上方法为切入点,综述了结合GIS技术的自下而上方法的研究现状,论述了采用该方法估算CH_(4)排放量的基本原理和成效,分析了影响估算的不确定性因素,指出采用结合GIS的自下而上方法可提高估算CH_(4)排放量的精确度,并对数据质量和模型准确度提出更高的要求。
Methane(CH_(4)), one of the principal greenhouse gases, is second only to carbon dioxide. It has great significance to estimate atmospheric CH_(4) emission accurately in achieving carbon peak and neutrality goals. Bottom-up, as one of the methods applied in quantifying CH_(4) emission, is widely used in various studies. However, it has great uncertainty of precision and accuracy. Combining Geographic Information System(GIS) technology with bottom-up method can yield a more reasonable and scientific result. Staring with the bottom-up estimation of CH_(4) emissions, this paper reviews some related research on bottom-up estimation of CH_(4) emissions combined with GIS, describes the basic principle and effect of this coupled method, then the causes of uncertainties were analyzed. It can conclude that GIS improves the scientific and reasonable of bottom-up CH_(4) emission estimates, but the higher quality of data and the higher accuracy of model are required in using this coupled method.
