Abstract: In order to predict and analyze monthly growth and overall production of cotton in Anhui Province in 2013, the author evaluated and early warned the cotton prenatal, delivery and postnatal production and development with CCGI which was counted through continuous survey from multi-point and multi-family. The results showed that: several climate disasters were extremely detrimental to the growth of cotton in Anhui Province in 2013, so the province average CCGI was only 92, and the general trend of cotton growth was significantly worse than in 2012. The cotton acreage of Anhui Province in 2013 was 255600 hm2, and decreased 10.1% comparing to the last year, while the total production was 237000 t, down 18.8%, and the lint yield was 927 kg/hm2, minus 6.5%. As the cotton market continued to slump, the cotton area was expected in 2014 in Anhui Province which would continue to decline, or down 13.2%, or reduced to 226667 hm2 or less.
