Abstract:

基于移动监测手段获取上海春季典型样带近地面CO2浓度监测数据,在明确近地面CO2浓度空间分布格局的基础上,分析了城市化水平以及土地利用类型对近地面CO2浓度的影响。结果表明上海市春季近地面CO2浓度空间分布呈现西高东低、北高南低的特征,空间异质性较为明显,市中心比郊区高出55.1μmol/mol(13.3%),存在着明显的城市"CO2"岛现象。城市化水平对于上海市近地面CO2浓度影响较为显著,总体上呈现随城市化水平上升而下降的趋势,距市中心距离每增加1km,CO2浓度下降1.56μmol/mol。上海市近地面CO2浓度与5km范围内下垫面土地利用类型相关性显著,其中近地面CO2浓度与林地以及建设用地覆盖率相关性最高,依次为-0.64和0.63。进一步分析表明近地面CO2浓度与土地利用类型的相关性在高度城市化以及城郊区域较高,在中低城市化水平区域较低。
