| Abstract: | In order to reveal the trend of climate change and the response of climate productivity in Yellow River Delta on global warming,we analyses the characteristics of climate change,according to the data of climate in 1959～2009,using symbolic statistics.Meanwhile we calculated the climate productivity in this area with Thornthwaite Memorial Model,and verified the mutation of climate using t-test technique.The results showed that the average annual temperature increased at the rate of 0.373℃/10a,which was greater than the northern part of China;The mutation was 1994;The contribution of increased temperature in winter to the annual of average temperature was the largest of the whole season.The annual fluctuation of annual precipitation changed tempestuously,however,the whole changed little;The annual evaporation and relative humidity declined fluctuant;The correlation of annual precipitation to climate productivity was significant,which was higher than the climate.The climate productivity was higher than normal during the 60s～80s,but in the 70s,90s,and nearly 10a,it was lower than normal.Cold-wetting climate was favorable for climatic productivity in the area,and the largest percentage of positive anomaly was 6.1%,and contrarily cold-drying climate was the worst,and the largest percentage of negative anomaly was 10.7%.So it is necessary to consider the effect of climate change when doing programs in the area of yellow River Delta. |
