摘　　要：利用1978—2013年数据测算了我国蔬菜生产集聚的空间基尼系数、FLQ值、全局和局部空间自相关指数,刻画了我国蔬菜生产集聚的时空特征,并对其影响因素展开了研究。结果表明我国蔬菜生产集聚总体呈现上升趋势并具有阶段性特征;蔬菜生产总体为中等集聚水平但各地集聚程度差异较大;蔬菜生产集聚呈现地域梯度和连片化特征。我国蔬菜生产地理集聚差异的驱动因素主要为:自然资源、市场需求、科技进步和政策制度等。Great changes have taken place in the spatial pattern of vegetable production in China since the reform and opening up and vegetable production shows the feature of geographical clustering. It is of great significance for vegetable production policy making to understand spatial-temporal characteristics and affecting factors. The spatial Gini coefficient, FLQ, global spatial correlation and local spatial correlation of vegetable production geographic agglomeration were calculated from the data from 1978 to 2012 in China. The article illustrates the spatial-temporal characteristics and analyzes affecting factors. The research shows that the vegetable production geographic agglomeration present a tendency of increase with stage characteristics. The vegetable production in total showed a medium agglomeration level but the regional agglomeration level varied. Vegetable production geographic agglomeration has the feature of regional gradient and contiguity. The driven force of vegetable production geographic agglomeration mainly include natural resources, market demand, technology progress and policies.
