辽宁省大豆气候生产潜力及气候资源满足率计算模式研究

Calculation Model of Climatic Potential and Its Fitness For Soybean Production in Liaoning Province

根据辽宁省27个气象站点1971～2000年间的气象数据,运用计算机技术对辽宁省大豆的光合生产潜力、光温生产潜力、气候生产潜力以及温度、水分的满足率进行计算分析.结果表明：大豆的光合生产潜力与总太阳辐射有很大的相关性,且由西部向东部递减;由于辽宁省省内南北区间跨度不大,因而形成光温潜力差异在研究区域内表现不明显,但作物（大豆）产量却呈现出由北到南递增的趋势.而且在大豆生育期内,由于省内各地降水分布不均匀,造成各地气候生产潜力差异很大,呈现出由西向东逐渐增加的趋势.在气候资源的满足率上,辽宁南部地区的温度和东部地区的降水均可较好满足大豆生长的需要,而北部地区和西部地区的生产潜力则受到温度和降水条件的限制.

The meteorological data in 1971-2000 at 27 meteorological stations in Liaoning Province were calculated for the photosynthesis production potential, temperature production potential and climatic production potential of soybean production and the temperature and moisture fitness for soybean production. The photosynthesis production potential of soybean correlated significantly with the total solar radiation, steadily decreasing from west to east. The spatial span between the south and the north was not broad enough to form an obvious radiation-and-temperature potential difference, but the crop （soybean） yield showed a decreasing trend from south to north. The uneven distribution of rainfall among regions in the soybean growth period caused a big difference in the climatic production potential of soybean, showing a tendency of steadily increasing from west to east. In the south, temperature fit soybean production; in the east, rainfall fit soybean production; while in the north and west, temperature and railfall did not fit soybean production respectively.
