中文摘要:
      利用天水市3个代表气象站1961-2005年气象资料及历年林果资料,分析了45年温度、降水、干旱指数时空变化特征及对果树生长的影响。研究表明,20世纪60年代以来,天水市气温总体呈上升趋势,特别是冬季气温上升较为明显,≥10℃积温和高温日数自90年代以来明显增加,90年代为40 a来的暖期和降水的最少期,干旱指数下降,春旱、春末初夏旱、伏旱出现几率增多。气候变化对林果业发育期、产量品质及种植布局均带来一定影响。
英文摘要:
      Based on the climate data from 1961～2005 of 3 representative meteorological stations and the data of fruit growing,the feature have been analyzed about the variation of temperature,precipitation,drought indexes and their influence to fruit tree growing in the last 45 years.The study indicates that since 1960s,the temperature has increased,especially in winter,accumulated temperature(≥ 10 ℃) and the days of heat have been increased since 1990s.The temperature was the highest and the precipitation was the lest in 1990s,the drought index dropped,spring drought,early summer drought and hot drought appeared more.The influence has been brought to fruit growing period,yield,quality,planting distribution because of climate changing.
