摘要
本文基于武汉市1998~2011年的土地变更数据及能源消耗数据,运用灰色关联度模型及Pearson相关分析法分别测度土地结构与能源消费碳排放总量、能源消费碳排放强度、人均能源消费碳排放量的关联度及相关系数。结果表明,土地利用结构与能源消费碳排放总量、能源消费碳排放强度和人均能源碳排放量三者关联度最高的分别是交通用地（0.884）、耕地（0.735）和园地（0.894）,对应的Pearson相关系数分别为0.923、0.777和0.915。关联度及相关系数都处于很高的水平,因此,合理组织土地利用对武汉市实现节能减排具有重要意义。
Based on the data of land change and energy consumption in Wuhan City during 1998 ~ 2011,the correlation degree and coefficients of land use structure with total carbon emission quantity,carbon emission intensity and per capita carbon emission of energy consumption were analyzed respectively with grey relational degree model and Pearson correlation analysis.The results showed that traffic land（0.884）,farmland（0.735） and garden plot（0.894） had the highest correlation degree with carbon emission quantity,carbon emission intensity and per capita carbon emission of energy consumption respectively with the Pearson correlation coefficients as 0.923,0.777 and 0.915 respectively.In conclusion,relational utilization of land had important significance to realizing energy conservation and emission reduction in Wuhan City.
