基于POI数据的玉林市优势农业产业空间分布分析

Spatial Aggregating Feature Analysis on Characteristic Agriculture of Yulin Based on POI Data

玉林市是广西壮族自治区农业大市,也是广西农业人口最多的城市。为优化玉林市优势农业产业空间布局,利用POI数据和综合比较优势指数,运用比较优势测算、核密度分析方法,分析了玉林优势农业及产业空间分布特征。结果显示,玉林中药材在全国范围内具有绝对比较优势,水果具有较强的比较优势,而粮食在广西区内的比较优势明显;玉林优势农业产业空间集聚特征明显,农业企业活动呈现出由中心向外围扩散的圈层分布特征,并以“五彩田园”为核心向周边扩散;玉林农业企业的空间布局与地区农业现代化程度、交通便利程度和经济发展的差异程度有着紧密的联系。据此,提出今后玉林市农业发展应以“五彩田园”为核心向外辐射,重点发展区域特色中药材的建议,并提出了相应的产业发展对策。

Yulin is a large agricultural city in Guangxi Zhuang autonomous region,and is also the city with the largest agricultural population in Guangxi.In order to optimize the spatial distribution of dominant agricultural industries in Yulin,the spatial distribution characteristics of dominant agricultural industries were analyzed by using the methods of comparative advantage calculation and nuclear density analysis according to POI data and compositive Comparative Advantage Index.The results showed that Chinese medicinal materials in Yulin have absolute comparative advantage in China,fruit has strong comparative advantage,and grain has obvious comparative advantage in Guangxi;the spatial agglomeration and distribution characteristics of agricultural enterprises are significant,the activities of agricultural enterprises spread from the center to the periphery of colorful pastoral in a circle;the spatial distribution of agricultural enterprises in Yulin is closely related to the degree of agricultural modernization,the convenience of transportation and the difference of economic development.Based on this,it was suggested that the agricultural development in Yulin in the future should focus on the development of regional characteristic Chinese medicinal materials with the core of colorful pastoral,and corresponding industrial development countermeasures were put forward.
