Status and Analysis of Cotton Fiber Quality Distribution in China and Suggestions Abstract：In order to stabilize and develop cotton production，improve the fiber quality and satisfy the diversification of textiles industrial，the fiber quality data of cotton samples，which was of 13 main cotton producing provinces from 2001 to 2005 were taken as the research target in this paper. The distributions of eight fiber quality characters in the Tenth-Five-Year Plan period including length， strength，length uniformity，micronaire，etc，were analyzed. It indicated that the cotton fiber length of our national production mainly ranged from 28mm to 29mm，the fiber uniformity index from 82% to 84%，fiber strength from 27 cN·tex-1 to 29 cN·tex-1，micronaire from 4.0 to 5.0，which showed it could satisfy the need of the spinning industry for middle and low spinning. The fiber of Yangtze River Region （Jiangxi，Hubei， Hunan）was longer，stronger and more uniformed，but the micronaire was a little higher，the color character was worse，and the grade was also lower. The fiber of the Northwest Inland Region （Xinjiang） had the best micronaire，color and grade. As for the Yellow River Region，the index of its fiber was between the above area.
