| Abstract: | 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 maize>potato>sweet potato>soy bean>rice and potato>soy bean>maize>rice>sweet potato,respectively;the fluctuation index of sowing area and yield of the five grain crops in Hunan province was ordered as soy bean>sweet potato>maize>potato>rice and potato>maize>soy bean>sweet potato>rice,respectively.The stable zone,the relatively stable zone and the fluctuation zone of sowing area and yield were determined for each main producing region. |
