中国棉花生产优势省域分析

中国棉区分布广阔,各地宜棉程度差别很大。在前人研究的基础上,利用1989—2003年的全国及各省区的生产统计资料,以规模优势指数、单产优势指数、集中度优势指数、综合优势指数、棉粮单产比指数、棉粮面积比指数对各省区近阶段产棉优势分布及部分省区优势变化进行了分析。分析结果表明:中国有新疆、河南、山东、河北、湖北、江苏、安徽,这7个稳定的棉花生产优势省区,天津可能成为新兴的棉花优势省区,总体而言,中国棉花生产优势在东部有所波动,略有减小的状态下,植棉重心向西北部偏移。

The Analysis on Dominant Provinces of Cotton Production in China

The cotton is planted wide in China,and the suitability varies in different area.Based on the previous research,a series of six indexes,scale priority index,yield per unit priority index,concentrated degree index,comprehensive priority index,were chosen to analyze the predominance cotton production and its variation is included from comprehensive priority index and another two index about the ratio of cotton to crop between 1989 and 2003.It indicates that there are seven preponderant provinces of cotton production in China and Tianjin will probably become a new and developing one.In general,the predominance of cotton production is changing and decreasing in the east,while it is increased in the northwest.
