摘要
建立基准时段,确定河湟谷地的气候因子影响系数,分析气候变化对河湟谷地粮食产量的贡献率。结果表明,作物生长季气候变暖主要发生在20世纪90年代,气候变暖对河湟谷地20世纪90年代粮食增产的贡献率为12.6%~17.4%,对21世纪初粮食增产的贡献率为12.3%~20.0%,相对东北黑龙江地区,气候变暖对河湟谷地的影响较小。
The referenced period was selected and the temperature-affecting coefficient was built to analyze the contribution of climate change to food yield. The results showed that warming occurs mainly in the crop growth season in the 1990 s. The contribution rate of the climate warming to food yield increasing in 1990 s was 12.6%-17.4%,and 12.3%-20.0% in 2000 s.
