| Abstract: |
| 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. |
