摘要
以首次提出的集中度指数、波动指数为主要指标,对湖南5种主要粮食作物近10 a生产集聚与波动状况进行了研究。结果表明,湖南省播种面积、产量的集中度指数排序分别为玉米>马铃薯>红薯>大豆>水稻、马铃薯>大豆>玉米>水稻>红薯,波动指数排序分别为大豆>红薯>玉米>马铃薯>水稻、马铃薯>玉米>大豆>红薯>水稻。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。
The first proposed cluster index and fluctuation index were taken as main indexes to study the production cluster and the fluctuation situations of five main grain crops in Hunan province in recent 10 years.The results showed that the cluster index of sowing area and yield of the five grain crops in Hunan province was ordered as maizepotatosweet potatosoy beanrice and potatosoy beanmaizericesweet potato,respectively;the fluctuation index of sowing area and yield of the five grain crops in Hunan province was ordered as soy beansweet potatomaizepotatorice and potatomaizesoy beansweet potatorice,respectively.The stable zone,the relatively stable zone and the fluctuation zone of sowing area and yield were determined for each main producing region.
