Dynamic Change Analysis of Grain Yield and Factors Based on Gray System in Northern Anhui Province

Abstract:

Considering some grain yield conditions of China, we considered that grain yield security in particular regard the sustainable development strategy is a pivotal position. Based on the statistical data from 1991 to 2010, grain problem in Northern Anhui Province is discussed in three aspects. With the help of the theory and method of grey system we found: The grain per unit area yield was primary element of grain yield, whose grey correlation degree was sort in the first; The grain-sown area and water conservancy facilities were main factors of which grey correlation degrees were respective sort in the second and third; However, the influence of natural disaster and net income of farmer per capita should not be ignored.
