摘要
市场、农产品流、服务区是城市农产品购销网络的三个组成要素。市场是农产品流的集散地、服务区的核心，它的规模和布局不仅制约农产品流的流向和流量，而且影响到服务区的空间特性。因此，调整农产品市场的规模和布局，是城市农产品购销网络空间结构优化的重要内容。
The market,traffic and service region of agricultural products are three compound factors of the purchase-sale network of urban agricultural products.They constitute a multilayer and netted spatial structure.The market is the collection-dispersal center of agricultural products and the core of the service region.Its scale and distribution not only restrict the flowing direction and volume of agricultural products,but also affect the spatial characteristics of service region.So the adjustment of the scale and distribution of agricultural products market is an important content in the optimization of the spatial structure of the purchase-sale network of urban agricultural products.
