Abstract: In the present study， agricultural carbon emission in Tibet during 1998\|2012 was estimated by carbon conversion coefficient method， which was put forward by IPCC. The relationship of agricultural input， carbon emission per unit area of breeding and planting industry with economic growth was explored by econometrics analysis via SPSS 115， and the compliance of these relationships with environmental Kuznets Curve was verified. It was shown that agricultural input， carbon emission per unit area of breeding and planting industry exhibited a significant inverted “U” shape， which possessed the characteristics of EKC hypothesis graphic trend. The turning point emerged in the year of 2015， 2007 and 2003. Agricultural carbon emissions， especially the carbon emission intensity of agricultural input would rise over a period with the elevated agricultural economic development level.

Key words: agricultural carbon emission, economic development, environmental Kuznets Curve, Tibet
