1960-2010年关中地区旱涝灾害对气候变化的响应
Characteristics of drought and flood and its response to climate change in Guanzhong plain in 1960 to 2010
摘要
Abstract
Based on meteorological data of Guanzhong plain from 1960 to 2010, the characteristics of climate change in Guanzhong plain and the change of drought and flood before and after the temperature jump were analyzed by linear regression analysis, Mann-Kendall test and Z index. The results showed that the annual average temperature is gradually increased in the past 51 years and the annual precipitation showed a downward trend, indicating a significant warming and drying trend in climate change. The time of the temperature jump occurred around 1995; after the temperature jump, the flood events in Guanzhong plain decreased by 3.6% and the drought events increased by 23.8%, indicating an obvious drought trend.关键词
