传统农区农业特色产业集群形成的阶段特征、时空演化及驱动力因素——以中牟县大蒜产业集群为例OA

Based on the evolution theory of agricultural characteristic industrial clusters,combined with the formation process of garlic industrial clusters in Zhongmu county,the stage characteristics,spatio-temporal evolution and driving factors of garlic industrial clusters were analyzed by using the analysis methods of stage evolution,time evolution and space evolution.The results showed that:(1)The evolution of garlic industry cluster in Zhongmu county could be divided into four stages:germination and slow development(before 1985),development and rapid growth(1985-1990),steady and slow growth(1991-2007),and decline and slow decline(after 2008).(2)From the characteristics of time evolution,the garlic industry cluster in Zhongmu county has obvious aggregation phenomenon,which has decreased in recent years.The variation coefficientCVin 2019-2020 showed a large change,reflecting that the garlic industry cluster was greatly affected by the recent COVID-19 pandemic.(3)From the perspective of spatial evolution,Guandu town and Hansi town have always been in the high agglomeration area,and the effect of specialization organization is obvious recently.The local autocorrelation scatter plot showed that the garlic planting area in each township had a positive spatial correlation.The change of the center of gravity reflects that the center of gravity of garlic planting has shifted to the east in recent years and that the development momentum of garlic industrial cluster in the east is good.
