- 摘要:
- 碳排放的不断增加导致了全球变暖等诸多气候问题，土地是碳排放的载体，土地利用方式对碳排放量有着重要的影响。运用文献分析法查找有关土地适宜性评价的相关研究，将碳平衡引入土地适宜性评价中，建立了城市圈土地碳平衡适宜性评价指标体系。应用全排列多边形图示指标法，分别从碳源和碳汇两个角度对武汉城市圈各城市的土地适宜性进行了评价，研究发现，碳汇适宜性较高的城市有咸宁市、黄冈市和孝感市，碳源适宜性较高的城市有仙桃市、潜江市、天门市，通过图示可以直观地发现各城市的优势和不足。以土地利用结构和土地碳排放当量为依据估算各城市碳源碳汇总量，通过计算平衡因子、碳源碳汇比例等综合指标分析各城市土地碳平衡潜力，结果显示，各城市碳平衡潜力差异显著，工业较发达地区在碳平衡方面一般处于劣势。在城市圈发展中，区域整体的碳平衡更有利于实现城市圈的协同发展。
- Abstract:
- Increasing carbon emissions has led many climatic issues such as global warming. Land is the carrier of carbon emissions, and different types of land uses have important effects on carbon emissions. Literature analysis was used to find land suitability evaluation study, carbon balance was taken into land suitability evaluation, and the index system of city circle land suitability evaluation was established based on the carbon balance. Full array polygon icon Law was used to make an objective evaluation from the two aspects of carbon sources and sinks land suitable for the city of Wuhan city circle. The carbon sinks high suitability cities are Xianning City, Huanggang City, Xiaogan City, while the carbon source high suitability cities are Xiantao City, Qianjiang City, Tianmen City. It can be very convenient to find out the advantages and disadvantages of cities in carbon balance. Estimation of the amount of carbon source and carbon sink by each city land use types and land carbon equivalent can reflect the potential of the city in the carbon balance by calculating the balance factor, carbon balance potential differences of cities are significant. The more developed industrial areas are generally at a disadvantage in terms of carbon balance. In the development of city circle, carbon balance of the region as a whole is more conducive to the realization of the coordinated development of the city circle.
