[目的]对湖南近10 年水稻生产集聚与波动状况进行研究。[方法]以2001 ～2010 年《湖南农村统计年鉴》为数据来源,以播种面积和产量的集中度指数( CDI) 、波动指数( VI) 为主要指标,对全省各主产区近10 年水稻、早稻、中稻及一季晚稻、晚稻、优质早稻、优质中稻及优质一季晚稻、优质晚稻生产集聚与波动状况进行研究。[结果]湖南省水稻、早稻、中稻及一季晚稻、晚稻、优质早稻、优质中稻及优质一季晚稻、优质晚稻的播种面积和产量的集中度指数排序存在差异,但波动指数排序相同; 明确了各主产区中播种面积和产量的稳定区、相对稳定区、波动区。[结论]为优化湖南水稻生产布局,促进水稻生产集聚发展,将比较优势转化为竞争优势提供了依据。
[Objective] The research aimed to study the concentration and fluctuation of rice production in Hunan in recent 10 years. [Method] Taking “Hunan Rural Statistical Yearbook” from 2001 to 2010 as the data source, taking the concentration index (CDI) and fluctuation index (VI) of sown area and yield as the main indexes, Rice, early rice, middle-season rice and the first season late rice, late rice, high-quality early rice, high-quality middle-season rice and high-quality late rice in late season and high-quality late rice. [Result] The order of concentration index of sown area and yield of rice, early rice, middle rice, middle season rice, middle season rice, middle season rice, late rice, high quality early rice, middle quality rice and high quality late rice were the same, but the volatility indexes were the same; The main producing areas of sown area and yield of the stable area, the relatively stable area, fluctuating area. [Conclusion] In order to optimize the layout of rice production in Hunan and promote the cluster development of rice production, it provided the basis for converting comparative advantages into competitive advantages.
