Abstract
From 2001 to 2002, an observation experiment based on satellite remote sensing was conducted in Xinghua City to study the difference between continuous rice monoculture and cotton-rice rotation rice in the rice ratio vegetation indexes or rice yields. This paper introduces the analysis method of rice yield difference developed for this experiment, and demonstrates it with the rice vegetation index. The results show that the average rice vegetation index or yield of cotton-rice and rice-rice modes is different. We have found enough experiment data to come to conclusion that rice yield under cotton-rice mode is higher than that under continuous rice monoculture.
