利用基于灰色评估的空间分区模型,在GIS和VB. NET的支持下,评估我国各地区农产品价格在春、夏、秋、冬4季的水平,并进行空间分区.结果发现我国农产品价格存在显著的空间梯度差异:东南沿海的价格明显高于西北内陆;东部的价格显著高于西部;大城市的价格水平高于中小城市的水平.高价区一般集中在长江三角洲,低价区一般集中在内陆地区及西北地区.夏季的价格总体水平高于春季;冬季的价格水平总体高于秋季.%Using space subarea model based on grey evaluation, supported by GIS and VB NET, this paper evaluates agriculture product's prices of various regions in China during spring, summer, autumn and win-ter and conducts space subarea. The results indicate that there are remarkable space grads differences ex-isting in prices of China's agriculture products: price in southeast coastal areas is obviously higher than that in northwest inland; price in east part is notably higher than that in west part; price level in big city is higher than in middle and small cities. The high price areas are generally concentrated on the Yangtze Riv-er Delta; while the low price areas are in inland and northwest regions. The general level of summer price is higher than spring, while the general level of winter is higher than autumn.
