摘  要：
[目的]研究辽西朝阳农村的气温和热量资源变化特征。[方法]选取1966～2010年辽西朝阳农村气象站资料,应用序列相关和气候倾向率等统计方法,对朝阳农村的气温和热量资源变化特征进行分析,掌握该农村的气候现状。[结果]1966～2010年辽西朝阳农村日平均气温、日最高气温和日最低气温的年均值呈波动变化,其中日最高气温年均值趋势升高增温幅度最大(0.328℃/10a),且显著水平最高,是气温升高的主体;日平均气温增幅(0.151℃/10a)和显著水平次之;日最低气温呈下降趋势,且显著水平不明显。在冬、夏半年时间尺度里,日最高气温平均值趋势升高明显,气候倾向率分别为0.417和0.250℃/10a,以冬半年升高最突出;日平均气温趋势性显著水平较低,日平均最低气温趋势性不显著。辽西朝阳农村≥10℃积温呈波动增加趋势明显,气候倾向率为42.590(℃.d)/10a,近45年趋势增加192(℃.d)。[结论]该研究为调整农业结构和品种布局等农业措施提供气候依据。

摘  要：
[Objective] The change characteristic of temperature and heat resources in rural area of Chaoyang in western Liaoning were studied.[Method] Based on the data from rural meteorological station in Chaoyang in western Liaoning from 1966 to 2010,the change characteristic of temperature and heat resources in rural area in Chaoyang was analyzed by means of serial correlation and climate tendency method,so as to master its climate situation.[Result] The annual average value of daily average temperature,daily maximum temperature and daily minimum temperature in rural area of Chaoyang in western Liaoning from 1966 to 2010 showed fluctuation change,and the annual average value of daily maximum temperature increased most obviously with the climatic tendency of 0.328 ℃/10 a,and next came daily average temperature(0.151 ℃/10 a),while there was no obvious decrease in daily minimum temperature.The average of daily maximum temperature in winter half year increased more obviously than that of summer half year,with the climatic tendency of 0.417 and 0.250 ℃/10 a,respectively;the trend of daily average temperature reached low significant level,and there was no obvious variation in daily minimum temperature.In addition,≥ 10 ℃ accumulated temperature in rural area of Chaoyang in western Liaoning went up obviously,with the climatic tendency of 42.59(℃·d)/10 a,namely it increased by 192(℃·d) in recent 45 years.[Conclusion] Our study could provide climatic reference for the adjustment of agriculture structure and varieties distribution.
