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.
