| 摘 要： | 利用作物生长动态统计方法，计算和分析了5～9月气温和降水变化对东北地区水稻、玉米、大豆3种主要作物生产潜力的影响，建立了各站气温、降水与作物生产潜力的关系式，并用来评估气温和降水变化对当年作物产量的影响，还讨论了未来气候变化对东北地区作物生产潜力的可能影响。

| Abstract: | By using crop growth trends statistics model, the impacts of temperature and precipitation variations on the potential productivity of three main crops (rice, maize, soybean) in China from May to September are calculated and analysed, and the relationships between temperature, precipitation of each station and potential productivity are set up, respectively, which would be used to assess the impact of temperature and precipitation variations on crop yield of the same year, and the possible impact of future climate change on crop potential productivity in Northeast China. |
