Research On The Temporal And Spatial Evolution Of Vegetable Specialty Villages

The problem of "agriculture,countryside and farmers" has always been the key and difficult problem in the development of national economy.The development of rural economy is the key to solve the problem of "agriculture,countryside and farmers" and to realize rural revitalization.As the pillar of village economic development,professional villages have significant advantages in accelerating the development of rural economy through the radiation of characteristic industries,and have gradually become one of the key areas of concern to researchers.Taking 483 Vegetable specialized villages in Shouguang City as an example,this study studied the evolution process of Vegetable specialized villages in Shouguang City by using survey and interview data,analyzed the evolution stage and spatial evolution characteristics of Vegetable specialized villages in Shouguang City,and revealed the evolution mechanism of Vegetable specialized villages.Based on the analysis,the following conclusions are drawn:(1)The development and evolution of Vegetable specialized villages are characterized by distinct stages.According to the changes in the number of Vegetable specialized villages and the growth of vegetable planting area during the development of Vegetable specialized villages in Shouguang City,the whole development process of Vegetable specialized villages was divided into three stages,namely,the initial stage(1989-1997),the development stage(1998-2007)and the mature stage(2008-2017).In the initial stage,the number of specialized villages is small and the growth rate is slow.Vegetable planting area in specialized villages is mainly small-scale.In the development stage,the number of specialized villages increased rapidly,and the vegetable planting area of specialized villages expanded from small-scale to large-scale.In the mature stage,the number of specialized villages continued to increase,but the growth rate gradually slowed down,and the vegetable planting area of specialized villages increased significantly compared with the previous stage.(2)The spatial change characteristics of Vegetable specialized villages are obvious.In terms of location distribution,the spatial distribution of Vegetable specialized villages in three stages was analyzed by statistical analysis,nearest neighbor index method and nuclear density estimation method in point pattern analysis.The results show that the Vegetable specialized villages are in the spatial distribution of agglomeration in the whole development process,but the agglomeration degree decreases from the initial stage to the mature stage.The spatial distribution of Vegetable specialized villages in different townships is quite different,Jitai Town and Sunjiaji Street have a higher degree of development.In the process of development,new agglomeration centers are constantly emerging,and eventually a circular layout of multiple agglomeration centers with hollow streets as hollow areas is formed.(3)The evolution of vegetable village is the result of many factors.In terms of resource endowment,the population and cultivated land resources of villages determine the formation speed of Vegetable specialized villages.Distance is negatively correlated with the formation of specialized villages,and has the greatest impact on the distance from the town center,while the distance from the county town and the nearest rural road has less impact on it.In the initial stage of vegetable village,the government plays a decisive role in the development of vegetable village.In the mature stage,market factors play a more significant role,directly affecting the development direction and state of professional villages,while the role of government factors is weakened,playing a complementary role to the market.Technical factors affect the whole development process of Vegetable specialized villages by changing the quality and form of production factors,improving the comprehensive quality of Vegetable specialized households,reducing the cost of vegetable cultivation and increasing vegetable output.Especially in the mature stage of Vegetable specialized villages,technological innovation promotes the further development of specialized villages.
