Abstract

《联合国气候变化框架公约》签订后,国内外学者开展了大量碳汇方面的工作,而碳汇与农业生态经济系统关
联性的研究较为薄弱。因此,作者通过野外采样和室内试验,结合课题组累积的15年调研资料,利用灰色关联分
析方法,分析县南沟流域碳汇与农业生态经济系统的关系,以期为碳汇与农业生态经济系统的研究与实践提供参
考。结果表明:退耕还林(草)工程实施以来,林草碳汇显著增加,年碳汇增量从2523.17Mg增加至4562.06Mg。
在碳汇增加的过程中,农业土地利用结构和产业结构(以收入结构为表征)的演替对其产生了较强的正向效果,土
地利用结构调整通过扩大林草面积增加碳汇量;产业结构的变化通过非农收入的增加和高效设施农业的发展减轻
对土地的压力,进而促进和稳固土地利用结构。根据研究结果,建议今后应进一步优化农业系统结构,以促使林草
碳汇的稳定增加。

Other Abstract

International and domestic researchers have carried out a lot of the work in carbon sequestration
since The United Nations Framework Convention on Climate Change was published,but research on the
relationship between carbon sequestration and agricultural ecological economic system is still comparatively
weak.In order to provide reference about research and practice of the relationship between carbon sequestration
and agricultural eco-economic system,this study analyzed carbon sequestration responses to the agricultural
eco-economic system in Xiannangou Watershed using grey correlation analysis method combined
field sampling,laboratory experiments,and 15years peasant household survey data.The results showed
that Carbon sequestration of forest and grass increased significantly after the implementation of the Grain
for Green Project,and annual carbon sequestration increased from 2523.17Mg to 4562.06Mg during the
period of 1998-2014.Agricultural land use structure and industrial structure had significant effect on carbon
sequestration.The adjustment of land use structure increasing the area of forest and grass increased
the amount of carbon sequestration;the change of the industry reduced the land pressure and then promoted
and secured land use structure by the development of efficient facilities agriculture and the increase of
system income and non-agricultural income.It showed that agricultural ecological economic system succession
process produced a strong positive effect on carbon sequestration potential.According to the results,
we should further optimize the structure of agricultural system,adjust the stand structure,and improve
the quality of grass to promote a steady increase of carbon sequestration.
