摘要
选用1961～2009年沈阳东陵区光温水气象资料,分析其气候资源趋势变化,为当地气候资源开发利用提供依据。结果表明,近49年沈阳市东陵区光能资源呈下降减少趋势,辐射年总量趋势减少528MJ/m2,日照时数年总量趋势减少333 h。热量资源呈增加趋势,年平均气温趋势升高1.04℃,活动积温趋势增加228℃。年降水量总趋势略有下降,降水资源各年代间变化较小,趋于稳定。
The meteorological data of light,temperature and water in Shenyang Dongling District during 1961-2009 were selected to analyze the trend variation of climatic resources and provide the basis for developing and utilizing local climate resources.The result indicated that light resource presented the decreasing tendency in Dongling District,annual radiation reduced by 528 MJ/m2,annual sunshine duration decreased by 333 h.The heat resource presented an increasing tendency,the average annual temperature increased by 1.04 ℃,active accumulated temperature increased by 228 ℃·d.The general trend of annual precipitation declined slightly,precipitation resource during every age changed slightly and would tend to be stable.
