摘　　要：基于1981-2010年年均气象数据(太阳辐射、降水、温度、蒸发量)、土壤数据(肥力、质地、盐碱度)、基础地形(高程、坡度)等,采用生产潜力逐级修订模型,逐步计算得到湖南省1 km格网的光合生产潜力、光温生产潜力、气候生产潜力和土壤生产潜力数据集。与现实粮食生产力情况相比,数据集具有良好的空间分布一致性,真实有效的反映了湖南省粮食生产潜力分布情况,为湖南省国土资源空间规划、农业生产布局等研究与生产提供重要的数据参考。The dataset of soil potential productivity of Hunan province of China is produced at 1km resolution based on progressively calculating models and the data of climate,soil and terrain by using GIS(Geographic Information System)technology.The aim of this study is to get the pixel based soil potential productivity data in 1km resolution from the table based statistical data in administrative regions and polygon based in administrative county boundary GIS data.The dataset includes data about the photosynthetic potential productivity,light and temperature potential productivity,climatic potential productivity and soil potential productivity.The data also covers temperature correction coefficients,moisture correction coefficients and soil correction coefficients.The geographic distribution of predicting soil potential productivity coincides with the one of actual crop productivity.

关 键 词：湖南省 光合生产潜力 光温生产潜力 气候生产潜力 土壤生产潜力
