【摘要】：碳排放与碳吸收是影响区域碳循环的重要因素,而碳排放和吸收与土地的利用类型关系密切,不同的土地利用类型其碳排放与碳吸收差异较大。借助碳排放与碳吸收的估算公式,以统计年鉴数据为依据,从不同土地利用类型的视角出发,估算了1995—2011年新疆土地利用的碳排放量与碳吸收量,同时分析了碳排放与经济增长的环境库兹涅茨曲线(EKC)关系。结果显示:1建设用地是主要的碳排放土地利用类型,林地、耕地和草地是主要的碳吸收土地利用类型;2土地利用碳排放总量和人均碳排放量逐年波动增加,增长速度较快;土地利用碳吸收总量逐年增加,但增长速度较慢;3不存在倒"U"型的建设用地利用碳排放环境库兹涅茨曲线,而存在倒"U"型的农用地利用碳排放环境库兹涅茨曲线;4土地利用碳吸收量大于碳排放量,存在碳吸收盈余的现象,但是盈余的空间有缩小的态势。
[Abstract]:Carbon emissions and carbon absorption are important factors affecting regional carbon cycle, and carbon emissions and absorption are closely related to land use types. Different land use types have great differences in carbon emissions and carbon absorption.Based on the estimation formula of carbon emission and carbon absorption, based on the statistical yearbook data, the carbon emissions and carbon absorption of land use in Xinjiang from 1995 to 2011 were estimated from the perspective of different land use types.At the same time, the relationship between carbon emissions and environmental Kuznets curve of economic growth is analyzed.The results showed that the proportion of construction land was the main land type of carbon emission, forest land, cultivated land and grassland were the main types of carbon absorption. The total amount of land use carbon emissions and the per capita carbon emissions increased year by year, and the growth rate was relatively fast.The total carbon sequestration of land use increases year by year, but the growth rate is slow. There is no Kuznets curve of carbon emission environment of inverted "U" type construction land.But there is a negative "U" type of agricultural land use carbon emissions environment Kuznets curve 4 land use carbon absorption than carbon emissions, there is a phenomenon of carbon absorption surplus, but the surplus space has a shrinking trend.
