摘要
以播种面积集中度指数、波动指数为主要指标,对湖南近10年优质稻生产集聚与波动状况进行了研究。结果表明,全省播种面积的集中度指数、波动指数排序分别为优质晚稻>优质早稻>优质中稻及一季优质晚稻、优质中稻及一季优质晚稻>优质晚稻>优质早稻。明确了湖南优质稻播种面积稳定区、相对稳定区、波动区,并提出了湖南优质稻发展建议。
This paper aimed at studying the agglomeration and fluctuation situation of good quality rice production in Hunan province during the past 10 years,taking the concentration index and the volatility index of sown area as the main indicators.The results showed that the orders of concentration index and the volatility index of sown areas were：good quality late-season rice good quality early-season rice good quality middle-season rice and good quality single-season late rice,and good quality middle-season rice and good quality single-season late rice good quality late-season rice good quality early-season rice,respectively.The stable areas,relatively stable areas and fluctuant areas of sown areas were defined.The proposals of developing good quality rice in Hunan province were proposed.
