银川市气候资源生产潜力研究

The climate potential productivity of Yinchuan

利用银川市1989—2014年的气象资料,选用迈阿密模型与桑斯维特纪念模型,计算银川市温度、降水、气候资源生产潜力,分析25年来3种气候生产潜力的变化规律、对粮食产量的影响以及3种气候生产潜力的利用效率.结果表明:银川光热资源丰富,降水资源相对光热资源不足,水热资源在时间上匹配不合理,阻碍了气候资源生产潜力的发挥,导致粮食产量波动.

Based on Meteorological data during 1989--2014 from Yinchuan City, three kinds of climate potential productivity was calculated by the Miami model and Thorntwaite Memorial model. We analyzed that law of climate potential productivity, the change of Yinehuan grain yield and the utilization efficiency of three kinds of climate potential productivity. The results show that： Yinchuan rich solar energy resources, precipitation resources are relatively than solar energy resources. The match of Yinehuan＇s precipitation and heat resources on time is not reasonable, resulting in the fluctuation of climate potential productivity and grain output.
