摘  要:
基于昌吉市1961—2009年主要作物生长季降水量和气温观测资料,采用Penman公式、Thornthwaite、Holdridge和de Martonne等方法计算了1961—2009年昌吉市生长季可能蒸散量和水分盈亏量、干燥度,并利用线性倾向估计法对生长季降水、温度、蒸散量、水分盈亏量和干燥度气候变化的主要特征进行了对比,分析了其变化趋势.结果表明:1961—2009年昌吉市生长季温度显著上升、潜在蒸散及水分亏缺量显著增加,导致昌吉市生长季的地表干旱呈现缓慢加重的趋势.但由于降水增加、地表干燥度略减少,使得地表干旱状况有所减缓,气候变化并未明显加剧该区的干旱化,即昌吉市主要作物生长季地表干湿状况总体呈缓慢暖干趋势.

摘  要:
Based on the data of precipitation and air temperature of the main crop growth season in Changji City during 1961 to 2009, the potential evapotranspiration, water budget and aridity index were analyzed by using the Penman、Thornthwaite、Holdridge and de Martonne. The results show that: During1961 to 2009, the temperature, the potential evapotranspiration and the quantity of water deficit has increased significantly during the growing sean, which caused the surface drought showed a slow increasing trend. However, because of the increasing of precipitation and the slight decrease of surface aridity, the surface drought has been slowed down.The climate change has not obviously aggravated the aridity of Changji. Overall, the warming and drying trend climate tendency of the growing season was slow in Changji during 1961 to 2009.
