烟台市土地利用结构与能源消费碳排放关联测度

Correlation Degree Between Land Use Structure and Carbon Emission of Energy Consumption in Yantai City

[目的]分析山东省烟台市各区县土地利用结构与能源消耗碳排放的关联测度及其变化规律,为合理利用土地资源与低碳城市的建设提供科学建议。[方法]基于烟台市1986—2012年各区县的土地利用结构和能源消耗数据,采用碳排放量计算模型,测算出其能源消耗碳排放总量、碳排放强度和人均碳排放量,并运用灰色关联分析法,测度烟台市各区县土地利用结构与能源消耗碳排放的关联度。[结果]1 1986—2012年烟台市能源消费碳排放总量由3.05×106 t上升到1.494×107 t,增加了3.9倍;2 2012年烟台市各区县土地利用结构与能源消耗碳排放量、碳排放强度之间关联度最高的土地利用类型为园地,与人均碳排放量关联度最高的用地为交通运输用地;3烟台市各区县土地利用结构与能源消耗关联度较高的分别是园地(0.812 8)、城镇村及工矿用地(0.812 0)、水域及水利设施用地(0.805 9);4 1986—2012年烟台市各区县土地利用结构与能源消耗碳排放关联度较大的地区依次是长岛县(0.980 4)、芝罘区(0.962 4)和莱山区(0.948 0)。[结论]烟台市土地利用结构与能源消耗碳排放存在着密切的关联性,土地利用结构与能源消耗碳排放的关联度在空间上存在着差异性。

[Objective] To analyze relationships between the land use structure and energy consumption data in Yantai City, Shandong Province and to provide scientific support for rational use of land resources and low-carbon urban construction.[Methods] Based on the data from 1986 to 2012, we used the carbon emission model to estimate its energy carbon emissions, carbon intensity and carbon emissions per capita consumption and employed gray relational analysis method to analyze the association of carbon emissions with land use structure and energy consumption in Yantai City.[Results] ① The total carbon emissions from the energy consumption in Yantai City during the period from 1986 to 2012 increased from 3.05×10^6 t to 1.494×10^7 t, increased by 3.9 times. ② The association between the land use structure and carbon emissions and energy consumption in 2012 showed that the land use type with the highest carbon intensity is orchard, while the land use type most relevant with per capita carbon emissions is land for transportation. ③ The land use type with closer relationship with energy consumption are orchard（0.812 8）, urban village and industrial land （0.812 0）, water and water conservancy facilities land （0.805 9）. ④ The counties with closer relations between land use structure and carbon emissions are the Changdao County（0.980 4）, Zhifu district（0.962 4） and Laishan district（0.948 0） between 1986 to 2012 in Yantai City.[Conclusion] Land use structure and carbon emissions energy consumption have close relations, and spatial differences exist in correlations between land use and carbon emissions from energy consumption.
