最近关于全球变暖性质的研究表明，气温可能发生不对称变化，夜间最低温度比白天最高温度上升得更快。我们利用大气环流模式(GCMS)输出的气候变化情景和EPIC(侵蚀生产力影响计算器)植物过程模型，结合非对称变暖的物理情景，研究了非对称温度变化对作物生产力的影响。我们的结果表明，全球变化对作物生产力的潜在影响在昼夜不对称变暖的情况下可能没有同等昼夜变暖情况下那么严重。
Recent studies on the nature of global warming indicate the likelihood of an asymmetric change in temperature, where night-time minimum temperature increases more rapidly than the daytime maximum temperature. We used a physically based scenario of asymmetric warming combined with climate change scenarios from General Circulation Models (GCMs) outputs and the EPIC (Erosion Productivity Impact Calculator) plant process model to examine the effects of asymmetric temperature change on crop productivity. Our results indicated that the potential effects of global change on crop productivity may be less severe with asymmetric day-night warming than with equal day-night warming.
