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.
