| 为探讨我国花生主产省花生单产与气象因素的关系，精准评估花生单产受气象因子的影响，选取了全国305个气象站点33年（1980-2012）的气象因子（日照、降水量和气温）数据和同期花生主产省花生单产数据，应用滑动平均法计算花生的趋势产量，再以所分离的气象产量作为因变量，利用改进的Fisher积分回归方法计算了各因子各生育期对气象产量的影响系数，科学构建气象因子与花生单产的数学模型，结果表明各省份花生全生育期日照、降水量和气温对气象单产的影响较大，花生单产气象模型拟合程度较高袁，可精准评估花生单产受气象因子的影响，指导花生生产。 |

| To assess the relationship between peanut yield and meteorological factors in major peanut province, search parameters and construct model for predicting peanut production, meteorological data (sunshine hours, precipitation and temperature) and peanut yield data were collected separately from 305 meteorological stations and National Bureau of Statistics of the People爷s Republic of China from 1980 to 2012 in China, which were used in model. Fisher integral model and Chebyshev orthogonal polynomials were used to analyze coefficients between meteorological factors (temperature, precipitation and sunshine hours) and the peanut yield in major producing provinces of China and to establish mathematics model between meteorological factors and peanut yield. Based on the coefficients between meteorological factors and peanut yield in different period, we could find that meteorological factors had great effects on peanut yield. The fitting degree of peanut yield meteorological model was very well, which could accurately predict peanut yield and be used to guide peanut production. |
