摘要
采用InVEST模型估算浦东新区2000年、2010年和2020年的碳储量,基于地理探测器对碳储量变化的影响因素进行分析。结果表明,研究期间浦东新区碳储量先增后减,在空间上表现为东部增多、中部减少、西部不变;土地利用程度是碳储量变化的主要影响因子,土壤类型和年均降水量是重要影响因素,双因子的交互影响力高于单因子;当高程范围为0 m~7 m、坡度>10.13°、无坡向、土壤类型为滨海盐土、年均温度为16.25℃~16.31℃、年均降水量为1132.41 mm~1150.02 mm、土地利用程度为200~268.24、人口密度为1.76万人/km^(2)~3.32万人/km^(2)、GDP为291799.79万元/km^(2)~644331.46万元/km^(2)时,浦东新区的碳储量增长最高。
The InVEST model was used to estimate carbon storage in Pudong New Area in 2000,2010,and 2020.The influencing factors on carbon storage changes were analyzed by geographic detectors.The results indicated that during the study period,carbon storage in Pudong New Area increased first and then decreased.In terms of spatial distribution,carbon storage increased in the east,decreased in the middle and remained unchanged in the west.The degree of land use was the main influencing factor of carbon storage change.Soil type and mean annual precipitation were the important influencing factors.The interaction influence of two factors was higher than that of one.When the elevation range was 0 m~7 m,the slope was greater than 10.13°,there was no slope direction,the soil type was coastal saline soil,the mean annual temperature was 16.25℃~16.31℃,the mean annual precipitation was 1132.41 mm~1150.02 mm,the land use degree was 200~268.24,the population density was 17600 people/km^(2)~33200 people/km^(2),and the GDP was 2917997900 yuan/km^(2)~6443314600 yuan/km^(2),the carbon storage in Pudong New Area increased the most.
