广东省农业科技园区的空间格局特征及影响因素
Spatial pattern characteristics and influencing factors of agricultural science and technology parks in Guangdong Province
摘要
Abstract
[Purpose]This study aims to scientifically evaluate the development process and spatial distribution of agricultural science and technology parks(ASTPs)in Guangdong Province,thereby exploring the potential and influencing factors of regional agricultural agglomeration.[Method]Taking multi-level ASTPs in Guangdong as the research subject,this paper employed a spatially modified gravity model,standard deviation ellipse(SDE)analysis,and grey relational analysis(GRA)to examine their developmental trajectory,spatial layout,and key determinants.[Result](1)ASTPs in Guangdong generally exhibited a multi-nodal agglomeration pattern,with relatively dense distributions in the Pearl River Delta and eastern Guangdong.The inclination angles of the SDEs aligned closely with the shape characteristics of administrative divisions,indicating a relatively rational overall layout.However,coverage density remained comparatively low in the southwestern Guangdong.(2)Based on their networked collaborative potential,the province could be categorized into distinct core zones with varying characteristics:metropolitan agricultural development zones,mountainous three-dimensional agricultural development zones,land-sea synergistic agricultural development zones,and tropical specialty agricultural development zones.(3)Land-water factors,such as the proportion of arable land and the density of major river networks,were critical determinants shaping ASTP distribution patterns,with grey relational indices reaching 0.85 and 0.93,respectively.Meanwhile,economic development and technological innovation capacity also showed significant correlations(grey relational coefficients of 0.82 and 0.73),though their influence remained secondary to natural environmental factors.[Conclusion]Accelerating the integrated spatial planning of ASTPs in Guangdong can effectively support high-quality agricultural transformation in major grain-consuming regions.Future efforts should optimize macro-level planning and micro-level site selection by aligning them with local demands and foundational conditions.关键词
