摘要
“双碳”背景下,城市绿色空间作为城市生态系统中最重要的绿色基础设施受到广泛关注,研究其对城市碳排放的抵消作用具有重要意义。采用统计学以及地理学方法,对中国297个城市进行绿色空间抵消碳排放能力估算并对固碳量进行驱动力因素分析,以期揭示城市绿色空间固碳能力的地域差异与驱动因素,为城市规划与绿色低碳发展提供科学指导。研究结果表明:(1)中国城市绿色空间对城市碳排放的抵消能力呈现较为明显的阶梯分布特征,南方城市高于北方城市,沿海城市高于内陆城市;(2)市辖区建成区面积对城市绿色空间固碳量的影响最大,年均人口数量、城市建设用地面积与固碳量显著正相关,第一产业占地区生产总值的比重、第二产业占地区生产总值的比重以及水资源总量与固碳量呈负相关关系。
Under the background of"carbon peaking and carbon neutrality goals",urban green space,as the most important green infrastructure in urban ecosystem,has been widely concerned,and it is of great significance to study its offsetting effect on urban carbon emissions.Using statistical and geographical methods,this paper estimated the carbon emission offsetting capacity of green space in 297 Chinese cities and analyzed the driving factors of carbon sequestration,with a view to revealing the regional differences and driving factors of carbon sequestration capacity of urban green space and providing scientific guidance for urban planning and green and low-carbon development.The results show that:(1)the ability of urban green space to offset urban carbon emissions in China presents an obvious step distribution,with southern cities being higher than northern cities and coastal cities being higher than inland cities;(2)the built-up area of the municipal district is the biggest driving factor affecting the carbon sequestration of urban green space,the average annual population is significantly positively correlated with the urban construction land area and the carbon sequestration amount,the proportion of the primary industry in the gross regional product,the proportion of the secondary industry in the gross regional product,and the total water resources are negatively correlated with the carbon sequestration amount.
