The Study Of Agricultural Economic Spatial And Time Evolution Of Henan Provice

Agriculture, rural areas and farmers have been the focus of the central and the whole society. Henan province is a major agricultural province of China, and it has important significance for the analysis of agricultural economy in Henan province. Using the principal component analysis method, clustering analysis, spatial analysis of GIS, space law and self theory of Henan Province agricultural economy spatial temporal and spatial differences of evolution were in-depth analysis, draw the following conclusions:(1) The agricultural economy of Henan Province generally presents the gradient difference spatial pattern which is gradually reduced in the southeast of Northwest China. The Dabie Mountains in southeast, south of Funiu Mountain, Nanyang Basin and the eastern plain is the first step of agricultural economy, namely agricultural economy high value area, Northwest Central Plains and hilly agricultural economy in the second step, and agricultural economy the general area, Northwest Mountain and North Mountain and plain as the agricultural economy of the third step and agricultural economy low value area.(2) Through the cluster analysis, the agricultural economic differences in Henan province were analyzed, and the agricultural economy of Henan province was divided into four types.. The class Ⅰ region "planting industry driven", including the Nanyang, Xinyang, Zhumadian, Zhoukou, Xuchang, Shangqiu, Xinxiang, Jiaozuo, Anyang, Puyang and Sanmenxia; the class Ⅱ region "animal husbandry pull" consists of Hebi, Luohe, Pingdingshan; class Ⅲ region "second and third industry pull" Zhengzhou; type IV district "integrated pull type the type area including Jiyuan, Luoyang City, Xinyang City.(3) Using the spatial autocorrelation model to analyze the agricultural economy of 2004-2013 in Henan province. The results showed that around the city of Henan Province, per capita gross value of agricultural production and the Moran’s I index were positive, and are greater than expected for the corresponding year value, shows around the city of Henan Province, per capita gross value of agricultural production in the space distribution is not completely in the random state, but showed a certain spatial clustering, i.e. a higher per capita gross agricultural production of the city with the spatial characteristics of mutual accumulation.2004-2013, the Moran I s of agricultural economy in Henan is growing, which shows that the agricultural economic space is continuously enhanced in Henan province.. Using local Moran’s I index analysis, obtained the conclusion that the around the city, Henan Agricultural Comprehensive Economic in space has certain relevance, located in southeastern Henan Nanyang, Xinyang, Zhumadian, Zhoukou, Shangqiu agricultural economic levels were higher, showing semi ring wrapped the province, river south in the northern province of agricultural economic level is low, the difference is small. According to the conclusion of the study the analysis of motives of Henan agricultural economic spatial pattern evolution, from two aspects of natural factors and social economic factors for qualitative analysis; put forward Henan agricultural economic spatial pattern control method, including strengthening agricultural regionalization and comprehensive development, strengthen agricultural production base layout, promote agricultural specialization and commercialization.
