选用辽宁省28个站点1970—2009年温度、积温等气候资料，分析辽宁省近40 a的温度、积温变化，结合大气环流GISS模式的输出结果，评价气候变化对辽宁省种植制度的影响。结果表明：辽宁省2030年平均气温增加3．4℃；目前一年两熟制北界在绥中－喀左－朝阳－锦州－大洼－海城－长海一线；未来≥0℃积温空间变化自西南向东北递减，一年两熟制北界向东北移至西丰－新宾－草河口－桓仁一线。
選用遼寧省28箇站點1970—2009年溫度、積溫等氣候資料，分析遼寧省近40 a的溫度、積溫變化，結閤大氣環流GISS模式的輸齣結果，評價氣候變化對遼寧省種植製度的影響。結果錶明：遼寧省2030年平均氣溫增加3．4℃；目前一年兩熟製北界在綏中－喀左－朝暘－錦州－大窪－海城－長海一線；未來≥0℃積溫空間變化自西南嚮東北遞減，一年兩熟製北界嚮東北移至西豐－新賓－草河口－桓仁一線。

Using the climate data of temperature and accumulated temperature of 28 observation stations in Liaoning province in 1970—2009 to analyze the variation of temperature and accumulated temperature in recent 40 years in Liaoning province, and by combining the output result of atmospheric circulation GISS mode, to evaluate the influence of climate variation on cropping system in Liaoning province. The result shows that the average temperature increases 3.4℃in Liaoning province in 2030;presently, the north boundary of two crops a year is Suizhong-Kazuo-Chaoyang-Jinzhou-Dawa-Haicheng-Changhai; in the future, the space variation of ≥0 ℃ accu-mulated temperature will be decreased from the southwest to the northwest, the boundary of two crops a year will be Xifeng-Xinbin-Caohekou-Huanren moved from the north to the northeast.
