摘要
根据松嫩平原1951-2005年36个气象站的历史资料,分析了近44年温度、降水的年际变化特征,采用机制法,计算了松嫩平原农作物的气候生产潜力。在MAPGIS、SAS的支持下,探讨了农作物气候生产潜力的时空变化规律,分析了气候变化对气候生产潜力的影响,建立了气候因子与作物气候生产潜力之间的回归模型。
Based on the 1951～2005 Songnen Plain 36-year history of the meteorological data,analysis of nearly 44 years of temperature,precipitation in the inter-annual changes in the characteristics of the mechanism used method for calculating the Songnen Plain crop production and climatic potential.With the support of MAPGIS and SAS,the crops climate productive potential space and time change rule were discussed,and the climatic change to the climate productive potential influence was analyzed,then established the return model between climatic factors and the crop climate productive potential.
