| 摘 要： | 选择周边环境近50a相对改变较小,位于农村的气象观测站资料,应用序列相关和气候倾向率等统计方法,分析辽西农村环境下的气温趋势变化。结果表明:辽宁西部农村近50a年平均气温增暖幅度远小于周边城市的增温幅度。就年均值而言,平均气温、平均最高气温、平均最低气温呈增温趋势,其中平均气温和平均最高气温序列相关显著,增温明显。四季平均最高气温呈增温趋势,其中冬季、春季和秋季增温明显,冬季是增温的主要时段;四季平均最低气温上升、下降均不明显。周边城市升温幅度是辽宁西部农村的2.6倍。日最高气温是升温的主体,日最低气温不存在升温趋势,这一点与众多专家的研究结果不同。本研究在对研究对象气象站的选择时,尽量避开城市热岛效应的影响,旨在为研究农村气候变化,描述农村气候特征,评价农村气候生态环境提供客观的依据。

| Abstract: | The data used in this study were collected from weather observation stations located in the rural area,around where nearly 50 years less changes in surroundings.The accumulated trends of temperature variation in the western Liaoning province was investigated by the serial correlation and climate tendency rate to provide literature for the research on the change and characteristics of climate,as well as the evaluation of the ecological environment in rural area.The results showed that increase range of the m... |
