摘要
利用2000至2006年湖南省115个县(区、市)农业生产统计资料,以规模比较优势指数、效率比较优势指数、综合比较优势指数分析了湖南省玉米生产比较优势状况,并通过GIS软件进行空间表达.结果表明,湖南省玉米生产存在显著的区域差异,玉米生产具有规模、效率、综合比较优势的县(区、市)分别有40、96、54个.具有玉米生产优势的县(区、市)主要分布在武陵山脉、雪峰山脉、南岭山脉及湘东北丘陵山区.
Efficiency and integrated comparative advantages indices were calculated from the statistical data of 115 counties（districts or cities） in agricultural production between 2000 and 2006. The information illustrated the distribution of comparative advantage of maize production counties in Hunan province. The various comparative advantage category of the counties was expressed visually on the map with GIS software. The results indicated that different counties in Hunan province displayed significant regional differences from each others in the maize production; there were 40 counties of comparative advantage in scale, 96 in efficiency and 54 in integrated advantage; the comparative advantage of maize production counties were distributed primarily over the mountain and hilly country of Wuling mountain range, Xuefeng mountain range, Nanling mountain range and northeast areas in Hunan province.
