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 emission and carbon absorption are the important factors affecting regional carbon cycle, and they are closely related to land use types. Carbon emissions and carbon absorptions are quite different from different land use types. In this paper, the carbon emissions and carbon absorptions of different land use types in Xinjiang during the period from 1995 to 2011 were estimated based on the statistical data and using the carbon emission and carbon absorption estimating formulas, and the relationship between carbon emission and economic development was analyzed. The results are as follows: ① In Xinjiang, the construction land use was the main source of carbon emission, but the forestland, cultivated land and grassland are the main land use types of carbon absorption; ② The total carbon emission of land use and the per capita carbon emission were rapidly increased year by year, but the total carbon absorption of land use was slowly increased year by year; ③ There was no an inversed “U-shaped” Kuznets curve of carbon emission environment of construction land, but an inversed “U-shaped” Kuznets curve of carbon emission environment of farmland use; ④ The land use carbon absorption was higher than its carbon emission, there was a carbon absorption surplus, but the surplus space was in a decrease trend.
