| 摘 要： | 摘要：利用国家统计局《中国农村统计年鉴》1984-2003年的数据和同期年平均温度的观测数据，分析了我国不同地区20年间温度变化、农业生产资料投入以及播种面积变化对粮食总产的影响。结果表明，以温度升高为主要特征的气候变化对东北地区农作物增产有明显促进作用，对华北、西北和西南地区的农作物增产有一定抑制作用，对华东和中南地区的农作物粮食产量的影响则不明显。农业投入的增加对各地区的农作物增产在早期作用均显著，后期则增长缓慢。而各地区播种面积的变化对其总产量影响不太明显，但华东和中南地区农业播种面积的持续下降对粮食总产量有较大的抑制作用。

| Abstract: | Based on the data from China Rural Statistical Yearbook 1984-2003 of National Bureau of Statistics and the annual temperature in the same period, the impacts of temperature change, the agricultural investment and sown area changes on crop production were analyzed for different regions of China during the last 20 years. The results show that the climate change characteristic of rapid warming obviously promoted the growth of the total crop production in Northeast China, suppressed it in North China, Northwest China and Southwest China, and had not obvious effects on it in East China and Central-South China. The growth of agricultural investiment increased the crop production obviously in the various regions in the early stages, but the growth rate of production increase became slow in the later period. The continuous decrease in sown area had a negative effect on the growth of the total crop production in East China and Central-South China. |
