【摘要】 [目的]阐明西瓜甜瓜生产比较优势区域的空间特征,为海南省西瓜甜瓜产业战略决策提供重要的参考依据。[方法]以基于县域的海南省西瓜甜瓜播种面积、总产量和单位面积产量为研究单元,系统分析海南省西瓜甜瓜产量、效率、规模、集中度、综合比较优势和单位面积产量比、播种面积比及其空间分布特征。利用海南省18个县市农业统计资料,以产量比较优势指数、效率比较优势指数、规模比较优势指数、集中度比较优势指数、综合比较优势、单位面积产量比指数和播种面积比指数分析海南省西瓜甜瓜生产比较优势状况,并通过"地图汇"软件在地图上进行空间表达。[结果]海南省西瓜优势区域依次是陵水、万宁、文昌、东方、三亚、乐东和昌江等7个县市,琼东和琼南地区为海南省西瓜生产的综合比较优势区,琼西和琼北地区可作为后备发展区域;海南省甜瓜优势区域依次是乐东、陵水、三亚和东方等4个县市,琼南地区为海南省甜瓜生产的综合比较优势区,琼西地区可作为后备发展区域。[结论]以研究结果为依据,确定西瓜甜瓜为海南省近期发展的优势瓜菜农产品,对西瓜甜瓜进行优势区域布局规划,优先予以重点扶持建设,尽快提高产品产量、质量和市场竞争能力。更多还原

【Abstract】 [Objective] This study investigated the spatial characteristics of counties(cities) with comparative advantages in watermelon and melon production to provide reference bases in formulating strategies for the development of watermelon and melon industries in Hainan Province.[Method] By using the sowing area,total yield,and yield per unit area of watermelon and melon in Hainan Province as research units,the yield comparative advantage(YCA),efficiency comparative advantage(ECA),scale comparative advantage(SCA),concentration ratio comparative advantage(CRCA),comprehensive comparative advantage(CCA),ratio of yield per unit area(RYPA),sowing area ratio(SAR),and distribution characteristics of watermelon and melon were systematically analyzed.By referring to the agricultural statistic data of 18 counties(cities) in Hainan Province,indexes for each research unit(i.e.,the YCA index,ECA index,SCA index,CRCA index,CCA index,RYPA index,and SAR index) were established and calculated to determine the comparative advantage of watermelon and melon production in Hainan Province.A spatial expression of the research result on a map was conducted by using GIS software.[Result] Seven counties(cities) exhibited comparative advantages in watermelon production,namely,Lingshui,Wanning,Wenchang,Dongfang,Sanya,Ledong,and Changjiang.The Eastern and Southern Hainan Provinces had CCAs,and the Western and Northern Hainan Provinces could be reserved for future development.For melon production,four counties(cities) exhibited comparative advantages,namely,Ledong,Lingshui,Sanya,and Dongfang.The Southern Hainan Province had CCA,whereas the Western Hainan Province could be reserved for later development.[Conclusion] The result has showed that establishing watermelon and melon as dominant agricultural products is necessary for the future development of the industry and for the formulation of a layout of regions with advantages,where key support and construction should be provided preferentially with the aim to raise the yield,quality,and market competitiveness of products.更多还原
