摘要
1951年以来 ,黑龙江省呈明显的变暖趋势 ,1980年代以来增温尤其明显 ,是全国变暖最显著的地区。对比发现 ,全省水稻种植面积增减的阶段性变化与温度变化阶段之间存在着良好的对应关系 ,但水稻种植面积变化略滞后于温度变化。1980年代中期以来全省水稻种植面积的显著增加 ,特别是北部地区种植面积的显著增加 。
Heilongjiang Province has experienced a warming trend since 1951,especially since the 1980s,where the warming trend is the most obvious in China.Analysis of the relationship between the changes in paddy planting area and temperature change in Heilongjiang revealed that the stages of change in paddy planting area are corresponding to the stages of temperature change,but the former lags behind the latter by about 4～6 to 2～3years.The rapid increase in paddy planting area and the northward expansion of the paddy fields since the mid 1980s are response to the distinct rising trend of temperature since the 1980s.
