利用1971-2010年重庆地区34个地面气象站日值数据集，结合周广胜气候生产潜力模型，采用线性回归、Mann-Kendal突变、经验正交函数（EOF）等方法分析重庆地区蔬菜气候生产潜力。结果表明：重庆地区年平均蔬菜生产力呈下降趋势，并存在明显的突变，主要是由于降水量的减少；重庆市蔬菜气候生产潜力空间分布呈现渝东南、渝东北偏西地区偏高的特点，局地差异也较明显。当重庆气候处于暖湿型气候时对蔬菜的生长最为有利。
利用1971-2010年重慶地區34箇地麵氣象站日值數據集，結閤週廣勝氣候生產潛力模型，採用線性迴歸、Mann-Kendal突變、經驗正交函數（EOF）等方法分析重慶地區蔬菜氣候生產潛力。結果錶明：重慶地區年平均蔬菜生產力呈下降趨勢，併存在明顯的突變，主要是由于降水量的減少；重慶市蔬菜氣候生產潛力空間分佈呈現渝東南、渝東北偏西地區偏高的特點，跼地差異也較明顯。噹重慶氣候處于暖濕型氣候時對蔬菜的生長最為有利。

Based on a daily meteorological data set at 34 ground weather stations from 1971 to 2010 in Chongqing, the climatic potential productivity of vegetables was anlayzed by methods of a Mann-Kendall and an empirical or-thogonal function (EOF)combining a climatic potential productivity model developed by Zhou Guangsheng.The results indicate that the mean annual climatic potential productivity of vegetables is in a decreasing trend and has a significant abrupt change because of decreasing precipitation.The climatic potential productivity of vegetables is higher in the southeast and west-northeast of Chongqing.The climatic potential productivity has obvious local differences.The warm and wet climate is favourable to the growth of vegetables in Chongqing.
