黄河三角洲典型区土地利用碳排放动态变化特征

Dynamic Characteristics of Carbon Emission from Land Use in Typical Areas of the Yellow River Delta

摘要: 土地利用变化引起的碳排放不容忽视，研究区域土地利用碳排放特点对于经济建设、节能减排和环境保护有非常大的意义。本文以黄河三角洲地区东营市为研究区，通过获取1990年至2015年土地利用类型数据和能源消耗数据，计算并分析了不同土地利用类型碳排放变化特点及其区域碳排放影响因素。结果表明：东营市的碳排放量整体呈增长趋势，从1990年886.97 × 10³ t，增长到2015年的43689.23 × 10³ t，增长幅度较大。建设用地为主要碳源，对碳排放量起主要影响作用，水域是主要碳汇。随着城市化和工业化的进程快速发展，能源消耗量逐渐增加，从而使碳排放量增加，到2015年主要能源碳排放量达到43507 × 10³ t，25年增长了42782 × 10³ t。第三产业生产总值和居民人均消费水平对能源消耗影响最大。

Abstract: The carbon emission caused by land use change can not be ignored. It is of great significance for economic construction, energy conservation and environmental protection to study the carbon emission characteristics of regional land use. This paper takes Dongying City in the Yellow River Delta as the research area, calculates and analyzes the characteristics of carbon emission change and regional carbon emission image factors of different land use types by obtaining the data of land use types and energy consumption from 1990 to 2015. The results show that the overall carbon emission of Dongying City shows an increasing trend, from 886.97 × 10³ t in 1990 to 43689.23 × 10³ t in 2015, with a large increase. Construction land is the main carbon source, which has a major impact on carbon emissions. Water area is the main carbon sink. With the rapid development of urbanization and industrialization, the energy consumption gradually increases, thus increasing the carbon emission. By 2015, the carbon emissions of major energy sources have reached 43507 × 10³ t, with an increase of 42782 × 10³ t in 25 years. The GDP of the tertiary industry and the per capita consumption level of residents have the greatest impact on energy consumption.
