应用黄土高原地区７２站６０～８０年代的气象资料，分析了气候变化对玉米生产潜力的影响。结果表明，虽然整个黄土高原８０年代年平均气温有变暖趋势，但影响玉米生长期内的温度并没有增高，反而有所降低，以致８０年代玉米的光温生产潜力均较６０、７０年代减少。由于降水变化的影响，除陕西省外，其它省区８０年代气候生产潜力均高于６０、７０年代。
Using the meteorological data of 72 stations from the 1960s to the 1980s in the Loess Plateau, the influence of climate change on the production potential of maize was analyzed. The results showed that although the average annual temperature of the Loess Plateau increased in the 1980s, the temperature in the growth period of maize did not increase but decreased, so the potential of light and temperature production in maize in the 1980s was lower than that of the 1960s and 1970s . Due to the influence of precipitation change, except for Shaanxi Province, other provinces and autonomous regions have higher climate productivity potentials in the 1980s than in the 1960s and 1970s.
