摘要:基于泾河上游(泾川水文站以上)52年(1954-2005年)的径流和气象年数据,研究了上游地区的气候和径流变化特征,发现年降水量变化趋势不明显、器皿年蒸发量有微弱下降趋势,而年径流量却呈明显降低趋势。根据年降水量-年径流深的双累积曲线,划分出了径流变化的5个阶段分别为1954-1960年、1961-1971年、1972-1980年、1981-1997年和1998-2005年。并以1954-1960年段作为基准期,定量估算了其他年段内人类活动和年降水量变化对年径流深变化的贡献,发现除1991-1997年段降水量偏低对径流减少起很大作用以外,在其它年段径流的变化更多的受到人类活动的影响,在1961-1971年、1972-1980年和1981-1990年3个年段,人类活动对径流增加的贡献量分别为52.71,9.22,3.42 mm;而降水仅在1961-1971年对径流具有增加的贡献量为5.38 mm,在其它两个年段对径流具有减少的贡献量,分别为2.85 mm和2.93 mm;在1998-2005年,相对于降水量对径流的增加贡献量为1.73 mm的情况下,人类活动对径流的减少具有较大的贡献量为24.87 mm。最后,探讨了进一步定量区分气候变暖和具体人类活动对蒸散和径流变化贡献的研究需求。
This paper analyzed the characteristics of climate and runoff of Jing river upstream in the past 52 years(1954-2005) based on the measured data of climate and the hydrological data at Jingchuan station which is the main controlling station on the upstream.The research fund that the runoff series showed a significantly downward tendency while the precipitation was even and pan evaporation had weak downtrend,indicating that the down trend of runoff was caused by human activities.The double mass curve method were used to detect the abrupt change and made off four stages: 1954-1960,1961-1971,1972-1980,1981-1997,1998-2005.We obtained a regression equation based on the data of precipitation and runoff in 1954-1960.Using this equation the impact of human activities increasing on runoff can be quantified after 1960.The calculated results showed that except that low precipitation was the main reason leading to runoff reducing in period 1991-1997,human activity was the more important reason that impacted the runoff variation in other periods.For example,human induced runoff increasing were 52.71,9.22,3.42 mm in three periods 1961-1971,1972-1980 and 1981-1990 respectively,but precipitation induced runoff increasing was 5.38 mm only in the period 1961-1971 and runoff decreasing were 2.85 mm,2.93 mm in other period 1972-1980 and 1981-1990 respectively;In addition,compared to precipitation that induced runoff increasing 1.73 mm,human activities induced runoff decreasing were 24.87 mm in the period 1998-2005.Finally,we discussed that further quantitative distinguish the contribution of climate warm and specific human activity on variation of evapotranspiration and runoff was the research requirement.
