摘要

[目的

]

为了分析土地利用变化对碳排放的影响

以洪洞县为例

研究分析县域尺度上土地利用变化的碳排放效应。[方法

]

选取2000

2010和2013年山西省洪洞县遥感影像

通过解译遥感影像

最终获得洪洞县的土地利用数据。采用碳排放估算模型

估算了洪洞县13 a不同土地利用变化导致的碳排放效应。[结果

]

2000-2013年洪洞县的碳排放量呈现逐年增长的趋势

期间净碳排放放量共增加了6.12×10

t。作为主要碳源汇——建设用地和林地

二者的面积不断增长

但建设用地带来的碳排放远超过林地所能吸收的量。洪洞县各个乡镇在这13 a中的净碳排放空间差异变化明显。[结论

]

优化县域土地利用结构

能够有效地减轻碳排放问题。

Abstract

[Objective] In order to investigate variations of carbon emission in response to land use changes

this paper analyzed carbon emission influence by land use change taking Hongdong County

Shanxi Province as example on county scale.[Methods] The land use data was obtained based on the interpretation of the remote sensing image of Hongdong County in 2000

2010 and 2013. And the carbon effect caused by different change of land use about Hongdong County in 13 years was estimated by adopting the carbon emission estimation model.[Results] The carbon emissions presented the trend of increased year by year in Hongdong County and the net carbon emissions was increased 6.12×105 t from 2000 to 2013. As the major carbon source and carbon sinks

forest and construction land were in the state of growth

while the carbon emissions caused by construction land far beyond forest carbon absorption. The net carbon emissions space difference change was obvious in each township in the 13 years.[Conclusion] Optimizing the structure of land use can effectively reduce carbon emissions.
