Analysis on Influence Factors of the Grain Total Output Fluctuation in Shanxi Province
摘要
Abstract
In order to understand the influence mechanism and function size of influence factors of grain yield fluctuation in Shanxi Province,it makes use of array material of grain yield during 1949 - 2009, and utilizes fluctuating index to analyze the fluctuation characteristics and fluctua ting range of grain total output in Shanxi Province, and the influence factors of the grain total output fluctuation are analyzed. From the study of the crop principle:total output = sown area x yield per unit area.it analyzes further grain sowing area and per unit area yield fluctuation to the influ ence size of the grain total output. The result shows that the per unit area output is the main factor of influencing the grain total yield fluctuation, the next one is the sown area of grain. During 1949 - 2009, the per unit area yield fluctuation to the influence of the grain total output fluctuation reaches 79.68% ,and the sown area to the influence of grain total output fluctuation is 18.07%.关键词
