| 摘 要： | 利用区位熵指数和K均值聚类算法(K-means)分析了京津冀地区13个市域单元和184个县域单元的蔬菜生产空间分布、集聚程度及分类。结果表明:京津冀地区市域蔬菜生产大致分为紧缩型、发展型和平衡型三类;县域蔬菜生产呈现一定的专业聚集度,区位熵两极分化趋势明显,可根据县域蔬菜生产特征将京津冀地区划分为4个蔬菜生产区。

| Abstract: | The spatial distribution,concentration degree and classification of vegetable production were investigated in 13 cities and 184 counties of Beijing-Tianjin-Hebei region,the location entropy index and K-means clustering algorithm were used in this survey.The results showed that the production patterns of vegetables in the Beijing-Tianjin-Hebei region at city level could be roughly divided into three types:compact type,development type and balanced type,while it showed a certain degree of professional aggregation at county level,and the polarization trend of location entropy was obvious.According to the characteristics of vegetable production at county level,the whole area could be divided into four vegetable production areas. |
