This paper, based on data 1996-2014, uses data standardization and evaluation model to measure China's development level of low carbon agriculture, and analyzes their variance among 31 provinces and prefectures, and three regions. Generally, China's low carbon agricultural development level is low among 50 countries/regions, including USA, UK, and Sweden reaches a higher level at mature stage, other forty nations(regions) like Switzerland, Japan and France reach a high level at forming stage. High carbon emission does not mean a low development level of low carbon agriculture, and vice versa. As for regions, eastern China is higher the central and western in low carbon agricultural development level. The variance in China's local natural conditions and social economy makes regional difference in low carbon agricultural development, resulting in different low carbon agricultural models.
