Abstract:

Modern agricultural industrial park is the spatial carrier of regional agricultural modernization construction and an important starting point for implementing the strategy of rural revitalization. Analyzing its spatial distribution characteristics and influencing factors is of great significance for promoting the high-quality development of agriculture and rural areas and increasing farmers' income and making them rich. Taking the provincial modern agricultural industrial parks built in Guangdong Province as the research objects, this paper analyzes the spatial distribution characteristics and influencing factors of modern agricultural industrial parks in Guangdong Province by using methods and tools such as nearest proximity index, nuclear density estimation, imbalance index, spatial autocorrelation analysis and geographic detector. The research indicates that: (1) modern agricultural industrial parks in Guangdong Province are mainly distributed in the Pearl River Delta and north of Guangdong, and the whole province and different regions are spatially clustered. The estimation of core density shows that modern agricultural industrial parks in Guangdong Province have formed a contiguous distribution pattern of "one heart and three cores" based on the Pearl River Delta region. (2) The distribution of modern agricultural industrial parks in Guangdong Province is not balanced. Among them, the Pearl River Delta region has the largest gap between cities and prefectures, while the gap in northern Guangdong is relatively small. County spatial autocorrelation analysis shows that there are obvious agglomeration areas of modern agricultural industrial parks in Guangdong Province, and there are three counties with obvious high-high agglomeration, namely Huangpu District in the Pearl River Delta region, Huazhou District and Dianbai District in western Guangdong Province. (3) Guangdong Province mainly relies on planting industry to build modern agricultural industrial parks, and mostly grain and oil planting, while taking into account the common development of other types. The agglomeration core of various modern agricultural industrial parks is different, but the overall characteristic of "multi-point agglomeration" is stable. (4) The total amount of farmland, water conservancy and irrigation, specialized agricultural towns, leading agricultural enterprises and other 12 factors have different degrees of influence on the spatial distribution of modern agricultural industrial parks in Guangdong Province, and there is a double-factor interaction among all factors, among which the leading agricultural enterprises and other factors have the strongest interaction. Modern agricultural industrial park is the result of a series of factors. In the future, we can promote the high quality development of modern agricultural industrial parks in Guangdong Province from the aspects of space planning, system design and local construction.
