Study On Evaluation And Spatial Difference Of Agricultural Economy Development In Counties Of Hubei Province

County economy and city economy are important components of China's economic development and the most basic unit in macroeconomic regulation.County economy is of great significance for the leap-forward development of regional economic sectors.Using the principal component analysis method and GIS spatial analysis theory to study the spatial differences of agricultural economy in Hubei counties,the following conclusions are drawn:(1)The gap between the per capita agricultural output value in counties in Hubei Province is gradually expanding.Mean,extreme,and standard deviation all show a growing trend,indicating that the absolute gap between the average per capita agricultural economy in the county is continuously expanding.In the absolute gap,only the pole ratio has no obvious growth,and the change is relatively stable.This shows that the absolute value gap of the county-level agricultural economy in Hubei Province is widening,but the multiple relationship between the developed agricultural county and city and the backward county and city is relatively stable.(2)The relative gap between per capita agricultural output value in counties in Hubei Province has been continuously expanding.In 2008,the coefficient of variation of per capita agricultural output value in Hubei Province was 187,and the growth rate in 2016 was 429.Overall,with the exception of slight declines in 2009,2014,and 2015,the variation coefficient of per capita agricultural output value in the county of Hubei Province has been expanding,indicating that in 2008,-During the period of 2016,the relative gap between the per capita agricultural output value of counties in Hubei Province has been continuously expanding.(3)The gap in the relative rate of development of the county's agricultural economy is significant,forming a fast-developing region with Liangzihu District as the core and the core of Huangpi District,Yidu City,Dangyang City,Zhijiang City,Yinzhou District and Jiayu County.The relative development rate of most of the counties and cities in the fast-growing region is relatively low.(4)The spatial differences of agricultural economics in counties in Hubei Province are characterized by the spatial difference of "strong central and weak east and west",that is,the middle Jianghan plain area-Dahongshan area is the highest level of comprehensive agricultural economic level in our county,and the comprehensive level of agriculture is higher.The agglomeration is the center of this,and the comprehensive economic level of Huanggang and Xianning in the east is lower than that in the central part of the country.The Shiyan,Shennongjia and Enshi in the west are the areas with low agricultural economic level;at the same time,they gradually decrease toward the east and the west with the Jianghan Plain as the center.Circle layered space pattern.(5)In 2008,the county-level agricultural economic level in Hubei Province presented the spatial characteristics of "strong central and weak east and west",and the circular spatial pattern of decreasing value from east to west in high-value areas of Zaoyang,Zhongxiang,Tianmen,Xiantao and Jianli counties.And the axis of things symmetrical relationship.That is,Zaoyang,Zhongxiang,Tianmen,Xiantao,and Jianli County cross the north and south,forming a county-level agriculture in Hubei Province,with a regional scale of economic value,declining eastward and west,and the farther the distance,the greater the gap in agricultural economic level.The second highest value of agricultural economic development is:Sui County,Yicheng,Jingshan,Shayang,Qianjiang,Hanchuan,Public Security,Honghu,Jiangxia,Huanghua,Zhijiang,Dangyang,Yiling and other places,close to the central agricultural economy.The high-value zone and the low-value zone are:West Yunnan,Fangxian,Shennongjia,Xingshan,Zigui,Wufeng,Hefeng,Xuanen,Laifeng,Tuanfeng,Tongshan,etc In the region,the agricultural economy in these regions is the most backward.In addition to the topographic reasons,it also includes inaccessibility from cities and transport lines,inaccessibility to external contacts,low level of industrialization of agriculture,relatively obstructed industrial development,and failure to create distinctive agricultural brands.(6)Although the county-level agricultural economy in Hubei Province still showed the spatial characteristics of "high middle and low east and west" in 2016,the characteristics of the circle were not as significant as in 2008,and the high value band of the central agricultural economy was not sufficiently noticeable and was more subtropical.Instead,high-value areas are located in the outlying areas of the Jianghan Plain,mainly including Fuyang,Zaoyang,Dangyang,Zhijiang,Huanghua,and Jianli,while the areas with the Jianghan Plain as the core form the second highest value areas,including the counties,and Cities,Zhongxiang,Jingshan,Shayang,Tianmen,Qianjiang,Xiantao,Hanchuan,Honghu,Public Security,Yiling,Yidu,Jiangxia and Xinzhou have caused this change because the level of agricultural economy in the plains began to decline.The growing level of agricultural economy in the outskirts of the plains shows that the agricultural economy is not only related to the terrain,but also has a lot to do with the level of economic development and the level of agricultural processing industry.The county's low-value areas for agricultural economic development have evolved into Shennongjia,Xingshan,Badong,Jianshi,Hefeng,Wufeng,Xuanen,Laifeng,Xianfeng,Tuanfeng and Tongshan,and the agricultural economically backward regions have become more concentrated,especially to the southwestern Hubei Province.Enshi direction agglomeration.(7)According to the spatial evolution characteristics of Hubei's agricultural economy,Hubei Province is divided into four types of regions,namely,the developed agricultural economy,the sub-developed agricultural economy,the less developed agricultural economy,the underdeveloped agricultural economy,and developed regions.Taking Jianghan Plain as the core,the more developed areas are mainly located in the outlying areas of Jianghan Plain and along the plains of the Yangtze River.The more backward areas are located in the hilly areas of western Hubei and eastern Hubei,and the backward areas are in the mountainous areas of western Hubei and eastern Hubei.According to the actual situation in Hubei Province,three suggestions were put forward for the establishment of an efficient agricultural area in the central part of the country,the development of the agricultural economy in the mountainous areas in the west,and the development of market-oriented agriculture in the east.
