摘要
以山西省为研究区,在农业生产潜力计算与分析系统的支持下,以太阳辐射数据、气象观测数据及粮食产量数据为数据源,对山西省11个地市的光合生产潜力和光温生产潜力进行了计算和分析,并运用SPSS分析软件对生产潜力值与实际粮食产量进行了相关性分析,以找出与实际产量相关性最大的潜力模型。这对于指导山西省农业生产,提高粮食生产能力具有非常重要的意义。
The paper took Shanxi province as the study area, with the help of the calculation and analysis system of agricultural po- tential productivity, with solar radiation data, meteorological data and grain output data as data source, calculated and analyzed the photo- synthetic potential productivity and temperature potential productivity of eleven cities in Shanxi province, discovered the maximum po- tential model on the basis of correlation analysis to potential productivity value and the actual output of grain with SPSS. It can guide agri- cultural production of Shanxi province, and enhance the grain production capacity.
