石油型资源城市低碳发展路径研究

LOW-CARBON DEVELOPMENT PATHS OF PETROLEUM-BASED RESOURCE CITIES

采用基于能源消费的碳排放和不同土地利用的碳承载能力计算石油型资源城市的生态赤字,并结合不同产业空间划分对8个石油型资源城市不同产业空间碳足迹进行测算。研完结果显示:(1)我国石油型资源城市现阶段的生产性土地面积远远不足以补偿碳足迹,生态赤字为1 957.39hm^2,相当于研究区域总面积的近3倍。(2)生态赤字总量最大的为东营,其次为大庆,总量最小的是玉门和任丘。而人均生态赤字较大的城市为东营和克拉玛依,最小的是茂名和濮阳。(3)不同产业空间碳足迹总量上,工业空间碳足迹最大,占碳足迹总量的48%:其次为生活、商业空间,占42%;其他空间碳足迹一共占到10%。因此,石油型资源城市短时期内应走"支柱产业广化深化"低碳发展路线,并在此基础上制定"渐去资源化"和"多元化"的长期低碳转型目标。

The article, based on energy consumption-based carbon emission and the carrying capacity of different land uses, calculates the ecological deficit of petroleum-based resource cities. According to the spatial division of different industries, the carbon footprint of different industrial spaces in 8 petroleum-based resource cities are then calculated. Results show that： first, the productive land area of China＇s petroleum-based resource cities is far from compensating the carbon footprint. The ecological deficit is 1,957.39 hm^2, nearly 3 times as much as the total study area; second, Dongying has the largest total ecological deficit, followed by Daqing, whereas the smallest are Yumen and Renqiu. Dongying and Karamay have the largest per capita ecological deficit, and the smaller are Maoming and Puyang; third, among different industrial spaces, industry space has the largest total carbon footprint, accounting for 48% of the total, followed by living and commercial spaces which account for 42%; others account for 10%. Considering this, petroletma- based resource cities in recent years should stick to a low-carbon development path of ＂diversifying and deepening the pillar industries＂, and on the basis of that, they can formulate long-term low-carbon transition targets characterized by ＂gradual removal of resource priority＂ and ＂diversification＂.
