基于遥感和统计数据的成都市碳氧平衡分析

以四川省成都市为研究区,利用2014年Landsat-8 OLI遥感影像,提取该区土地利用/覆被数据,并结合经济、交通、生产耗能等基础统计数据,构建碳-氧平衡分析模型,对2014年碳氧收支量进行了研究,并对碳-氧平衡状况进行分析评价。结果表明,成都市2014年碳平衡系数为-0.049,氧平衡系数为-0.503。由于成都市东中西部社会活动功能差异和土地覆被类型分布不均,导致成都市19个行政区的碳氧平衡差异明显。最后,基于研究结果,对降低碳释放、社会经济活动和生态空间格局方面提出相应建议,可为成都市生态文明建设提供科学依据。

An Analysis of Carbon-oxygen Balance in Chengdu City Based on RS and Statistic Data

This paper takes Chengdu city of Sichuan Province as the research area.Using the remote sensing images in 2014 to extract and use/cover data of this region,combined with economy,transportation,energy production and other basic statistical data,model analysis of carbon oxygen balance,then the balance of carbon and oxygen were studied,and the carbon oxygen balance condition was analyzed and evaluated.The results show that in 2014 the carbon balance coefficient was-0.049,the oxygen balance coefficient was -0.503.Due to the differences of social activities and land cover types in the eastern and western regions of Chengdu,the carbon and oxygen balance of the 19 boroughs of Chengdu Cityobviously different.Finally,based on the analysis of the research results,this paper puts forward some suggestions to reduce the carbon release,social economic activities and ecological spatial pattern,and provides scientific basis for the construction of ecological civilization in Chengdu city.
