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Pear-son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。
本文基于武漢市1998~2011年的土地變更數據及能源消耗數據,運用灰色關聯度模型及Pear-son相關分析法分彆測度土地結構與能源消費碳排放總量、能源消費碳排放彊度、人均能源消費碳排放量的關聯度及相關繫數。結果錶明,土地利用結構與能源消費碳排放總量、能源消費碳排放彊度和人均能源碳排放量三者關聯度最高的分彆是交通用地(0.884)、耕地(0.735)和園地(0.894),對應的Pearson相關繫數分彆為0.923、0.777和0.915。關聯度及相關繫數都處于很高的水平,因此,閤理組織土地利用對武漢市實現節能減排具有重要意義。
