山西县域农产品区位比较优势与空间分布

Research on Regional Comparative Advantage and Space Distribution of Agricultural Products in Counties of Shanxi Province

运用区位商值法测量山西96个县级行政区域(剔除23个市辖区)农产品区位优势,结合空间地理数据绘制优势作物分布图,在山西粮食作物及经济作物传统种植的基础上,为山西"一县一业"、"一村一品"的建设提供实证分析。研究表明,县域优势农产品综合比较优势在不同农产品作物上体现出不同的特征,山西的小麦产区主要分布在临汾盆地、运城盆地、太原盆地;玉米种植以太行山区及晋南、晋中、大同、忻定四大盆地为主;杂粮生产以忻定盆地、太行山地区为主;蔬菜种植以晋南、晋中、忻定、上党和大同五大盆地为主。油料作物中油菜籽主要集中在山西省南部冬油菜产区,向日葵在忻州市黄河及其支流西北流域内集中分布,花生在山西境内汾河、沁河等盆地流域有分布,胡麻以晋西北种植为主。

By applying the method of location quotient value to measure location advantages of agricultural products of 96county- level administrative areas in Shanxi（excluding 23 municipal districts）, this paper makes advantage of crop distribution map by combining spatial geographic data. On the base of traditional cultivation of food crops and economic crops in Shanxi, it provides empirical analysis to construction of ＂one county one industry＂, ＂one country one product＂ for Shanxi province. The results show that comprehensive comparative advantages reflect different characteristics in different agricultural crops. Wheat regions of Shanxi are mainly distributed in Yuncheng basin, Linfen basin and Taiyuan basin. Corn plantation mainly lies in Taihang mountainous area, Jinzhong, Datong, Xinding four basins; coarse grain production is mainly in Xinding basin and Taihang mountainous area. Vegetables grow mainly in five basins.Oil- bearing crops also distribute in different areas. Rapeseed mainly concentrates in winter rapeseed production areas in southern Shanxi.And sunflower distributes in northwest concentration area of Xinzhou city along the Yellow River. Peanuts in Shanxi distribute in basins along Fen River and Qin River. It is given priority to flaxseed plantation in northwestern Shanxi.
