摘要
利用黑龙江省81个气象站1975—2004年30年的逐日气象资料及相应插值的网格同期逐日气象资料,采用WOFOST作物生长模型,模拟并分析了甜菜气候生产力的空间分布特征及主要气候影响因素。结果表明:黑龙江省甜菜早、中熟品种气候生产力在中部和东部由北向南递增,在西部由北向南递减;晚熟品种气候生产力在中东部和东部由北向南递增,在西部由北向南递减,在中西部处于中产水平。主要气候影响因素的分布对甜菜气候生产力的分布具有重要影响。利用气候生产力距平百分率、实际产量变异系数及与气候生产力密切相关的主要生育期的4个气候因子(枝叶繁茂期的平均气温、糖分积累期的平均气温、根快膨大期的降水量、糖分积累期的气温日较差),采用动态聚类分析方法,将黑龙江省甜菜早、中、晚熟品种的种植区域分别划分为8类、7类和6类种植气候区。
By using the 1975-2004 day-by-day observation data from 81 meteorological stations in Heilongjiang Province and the corresponding interpolated grids data, and based on WOFOST model, the climatic productivity of Beta vulgaris was simulated. The spatial characteristics of this productivity and the climatic affecting factors were analyzed. The results showed that the climatic productivity of early and mid mature varieties of B. vulgaris was increased from north to south in the central and east parts and decreased from north to south in the west part of the Province, while the climatic productivity of late mature variety was increased from north to south in the central-east and east parts, decreased from north to south in the west part, and was at middle level in the central-west part of the Province. The spatial distribution of the chief climatic factors had important effects on the climatic productivity of B. vulgaris. Taking the climatic productivity a- nomaly percent, variation coefficient of actual yield, and four climatic factors （ average air temperature at branch and leaf exuberating phase, average air temperature at sugar accumulating phase, rainfall at root expanding phase, and daily air temperature difference between maximum and minimum at sugar accumulating phase） in the major growth phases closely related with climatic productivity as the parameters, and using dynamic clustering analysis, the possible planting areas of early, mid, and late mature varieties of B. vulgaris in Heilongjiang Province were zoned into 8, 7, and 6 planting climatic areas, respectively.
