摘要 采用洛伦兹曲线与基尼系数,借助Arc GIS等软件从地区和县域两个尺度揭示2000—2012年京津冀地区蔬菜生产格局的时空分异特征。结果表明:京津冀地区蔬菜种植面积呈现"上升—下降—上升"的变化趋势,13年间总计增加了25.76万hm^2,蔬菜产量和蔬菜单产总体呈现增长趋势;县域蔬菜生产呈现"北进南移"的态势,京津所辖县域的蔬菜种植面积下降,冀北坝上高原区和燕山太行山山前平原区的蔬菜生产优势进一步显现,县域人均蔬菜种植面积呈现两极分化趋势。采用双重自组织模型将173个县域划分为都市型蔬菜生产区、山地丘陵特色蔬菜种植区、平原规模化蔬菜生产区、冀北高原错季蔬菜生产区、冀东南蔬菜生产区5个区。该研究结果可为京津冀地区蔬菜发展战略制定提供依据。 In our study, the Lorenz curve, Gini coefficient, and other methods were used to reveal the spatial-temporal pattern of vegetation production in Beijing- Tianjin- Hebei Region at regional scale and county scale. The result demonstrated that: vegetable sowing area in the region increased at first, decreased afterwards, and increased at last, with a total increment of 257.6 thousand hectares during the 13 years. The total vegetable output and per unit yield in the region presented generally growth trend. The advantage areas of vegetable production moved to the northward and southward of Beijing-Tianjin-Hebei region, for the sharply shrink of vegetable sowing area in Beijing and Tianjin, and the remarkable increment of vegetable sowing area in the Bashang plateau area and the piedmont of Taihang mountain and Yan mountain. Per capita vegetable sowing area at county level in Beijing- Tianjin- Hebei region presented polarization trend. 173 counties were aggregated into five vegetable production area by self-organizing dual zoning method, including urban vegetable production area, hilly special vegetable production area, plain large- scale vegetable production area,Northern plateau anti- season vegetable production area, and Southeast vegetable production area. Corresponding vegetable production development strategy was put forward at last, and this study can provide scientific basis for making vegetable production strategy in Beijing-Tianjing-Hebei region.
