摘要
宁夏沿黄经济区是我国西北地区重要的商品粮生产基地,研究确定该区农业优势产业,探讨区域农业产业空间布局,对优化配置区域农业资源,促进区域农业经济健康发展具有重要意义。采用区位商法对沿黄经济区农业及其内部各行业进行分析研究,结果表明:在全区范围内,种植业和渔业是沿黄经济区农业优势产业部门,且比较优势明显;除银川市、石嘴山市、灵武市之外,沿黄经济区其余各市县农业在全自治区范围内具有比较优势。以沿黄经济区为背景区域,通过计算比较各县市农业内部各行业的区位商,明确了沿黄经济区各县市的农业优势产业。根据沿黄经济区农业区位商的分析结果,结合沿黄经济区农业发展基础和发展态势,对沿黄经济区农业空间布局进行了研究,提出以城市为中心的"三圈层"结构布局和以农业资源为基础的"四轴带"结构布局的圈层轴带状农业空间布局形式。
The economic zone along the Yellow river in Ningxia is an important commercial grain production base in northwestern China. Discussing the advantage industry and the spatial layout of its agriculture industries will play a significant role in optimizing the allocation of agricultural resources and promoting the development of regional agriculture. We used the location quotient to analyse its various agricultural industrial sectors. The results show that farming and fishing are the dominant industries with remarkable advantages. Except for Yinchuan, Shizuishan and Linwu, the agriculture of other cities and counties in this area enjoy a comparative advantage. Then, we calculated the location quotient of each industrial sector to determine the advantageous agricultural industries in each city or county. According to the results and combining the developing trend, we studied the spatial distribution of the economic zone along the Yellow River and put forward two new patterns, namely, the three-circle structure with the city as its center and the four-ribbon structure on the base of agriculture resources.
