摘要：

运用同异分析法，分析和评价了信阳市1996～2005年度水稻生长期间主要气象因子，结果表明：1997、1999和2001年为丰产年份；1996、1998、2002和2004年为平产年份；2000、2003和2005年为歉产年份。分析方法切实可行，评价结论客观合理，为科学评价年度间的水稻气象产量提供了一条新的途径。

Abstract:

Main climatic factors of Xinyang were analyzed and evaluated by identical and different analysis method during rice growth and development in 1996～2005. The results showed that 1997, 1999 and 2001 were high yield years; 1996, 1998, 2002 and 2004 were normal yield years; 2000, 2003 and 2005 were low yield years. A new method was provided on scientific evaluating annual rice yield, the method was feasible, above conclusion was objective and reasonable.
