中文摘要: 根据19642013年汉江生态经济带气象站点的逐日观测数据,通过气候斜向率、Kriging插值法、M-K突变检验、小波分析等手段分别对各干湿要素进行趋势、空间、突变、周期分析。结果显示:该区域总体上经历了由湿变干的过程,年降水量、潜在蒸散量、干湿指数、水分盈亏量均呈线性下降趋势,突变分别发生于2005,1972,2006,2005年前后,且存在5,15,25 a左右时间尺度的干湿周期;该区域分为湿润、半湿润地区,各干湿气候要素在空间上基本呈山区少、平原多沿汉江自东南向西北逐渐变干的格局。综上,受多因素的影响,汉江中下游流域干湿气候空间分布相对复杂并逐渐变干,这种趋势已经凸显,应予以必要的重视,并采取科学可行的防旱减灾措施应对干湿气候变化。
英文摘要: According to the daily observation data of meteorological stations in the Hanjiang river ecological economic region from 1964 to 2013,we analyzed the trends,spatial changes,abrupt changes and cycles of dry-wet climate factors through climate inclination rate,Kriging interpolation,M-K mutation test,and wavelet analysis. Results suggest that the study region generally experienced a change from wet to dry. Annual precipitation,potential evapotranspiration,dry-wet index and water deficit all displayed a linear downward trend,with their sudden changes happened in 2005,1972,2006,and 2005,respectively. The dry-wet cycle is 5-year,15-year and 25-year in time scale. Moreover,the study region can be roughly divided into humid and semi-humid regions,and each dry-wet climate factor presents a trend ofsmall in mountainous area and large in plain areain space,which gradually becomes dry along the Hanjiang river from the southeast to the northwest. In conclusion,the dry-wet climate in the Hanjiang river basin is relatively complex and has gradually become dry. We should pay necessary attention to it and take scientific and feasible drought-resisting measures in response to dry-wet climate change.
