广东省现代农业产业园空间分布特征及影响因素研究

Research on Spatial Distribution Characteristics and Influencing Factors of Modern Agricultural Industrial Parks in Guangdong Province

现代农业产业园是区域农业现代化建设的空间载体,是实施乡村振兴战略的重要抓手,分析其空间分布特征及影响因素,对推动农业农村高质量发展和促进农民增收致富具有重要意义。本研究以广东省已建设的省级现代农业产业园为研究对象,运用最邻近指数、核密度估计、不平衡指数、空间自相关分析以及地理探测器等方法,分析了广东省现代农业产业园的空间分布特征及影响因素。结果显示,(1)广东省现代农业产业园主要分布在珠三角和粤北地区,全省及不同区域在空间上均呈集聚分布形态。核密度估计显示,广东省现代农业产业园已形成以珠三角地区为依托的“一心三核”集聚连片分布格局。(2)广东省各地市的现代农业产业园分布不均衡。其中,珠三角地区的地市差距最大,粤北地区差距相对较小。县域空间自相关分析显示,广东省的现代农业产业园存在明显的集聚区域,有3个县区高—高集聚比较明显,分别是珠三角地区的黄埔区,粤西地区的化州市、电白区。(3)广东省主要依托种植业建设现代农业产业园,且多以粮油种植为主,同时兼顾其他类型共同发展。各类现代农业产业园的集聚核心存在差异,但“多点集聚”的总体特征较稳定。(4)农田总量、水利灌溉、农业专业村镇、农业龙头企业等12个因素对广东省现代农业产业园空间分布有不同程度的影响,且各因素之间存在双因子增强交互作用,其中农业龙头企业与其他因素的交互作用最强。现代农业产业园是一系列因素交互协同作用的结果,未来可从空间规划、制度设计以及地方建设等方面推动广东省现代农业产业园高质量发展。

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.
