| The date collected by 19 meteorological stations located in five regions of the Weibei plateau and statistic methods were used to study the effects of the climate and climate productivity in Weibei plateau under global climate change. The results showed that, in Weibei plateau, the average annual and seasonal temperature tended clearly to rise and the temperature-increasing rate in spring and winter was higher than that in summer and autumn, while the annual rainfall and seasonal rainfall tended clearly to decrease, and the rainfall in spring and autumn tended to decrease and that in summer and winter tended to increase. The climate productivity tended to increase, and the “warm-et type” climate in the future was beneficial to crop production, under which the average climate productivity-ncreasing rate would be 12.1%, while the “cold-dry type” climate in the future was detrimental to crop production, under which the average climate productivity decreasing rate will be 18.3%. |
