摘要
为了对未来陕西地区农作物的区域分布、种植制度等方面提供科学依据,本文利用陕西省10个气象站台1958—2013年的降水和温度数据资料,利用Thornthwaite Memorial模型等方法研究陕西省气候生产潜力的时空变化。结果表明:①56年来,陕西省气候生产潜力微弱下降,具有南高北低的空间分布特征,总体由南至北递减。②气候生产潜力与温度的相关性不如降水显著,降水量的降低是限制气候生产力的主要因素。
In order to provide a scientific basis for Shaanxi Province in the regional distribution and planting systems of crops in future,the precipitation and temperature data of 10 meteorological stations in Shaanxi Province from 1958 to 2013 were used in this paper.By the means of the Thornthwaite Memorial model and other ways to study the temporal and spatial changes of the climate potential productivity in Shaanxi Province.The results show that:①The climate production potential of Shaanxi Province declined slightly in 56 years,with a spatial distribution characteristic of high in the south and low in the north,it is decreasing from south to south.②The correlation between climate potential productivity and temperature is not as significant as precipitation,and the decrease in precipitation is the main factor limiting climate productivity.
