Attribution Analysis of Runoff Change in the Upper Reaches of the Liuchong River Basin Based on Coupled Water-energy Balance Equation by LONG Da, DONG Qianjin, YANG Rongfang

“…Taking the upper reaches of the Liuchong River in Guizhou Province as the study area,this paper first analyzes the trend and abrupt change of the annual runoff at Qixingguan Station in the Liuchong River by the Mann-Kendall test and Pettitt test to find the abrupt change points,then,discusses the reasons of runoff change before and after the abrupt change points by the coupled water-energy balance equation,finally,calculates the contribution rates of precipitation,potential evapotranspiration and underlying surface to runoff change through the sensitivity analysis of their elastic coefficients.The results show that:The depth of runoff in the upper reaches of the Liuchong River shows a significant downward trend from 1971 to 2009,and a significant abrupt change occurred in 1986.By comparing the sensitivity of precipitation,potential evapotranspiration,and underlying surface to runoff change,it is found that the elastic coefficient of precipitation is the highest,followed by the underlying surface index,and finally the potential evapotranspiration,indicating that runoff is the most sensitive to the change of precipitation.In addition,based on the results of the contribution rate of the three factors to the reduction of runoff,it is found that the contribution rate of decreasing precipitation to runoff reduction is as high as 113.3%,followed by the change of underlying surface,with a contribution rate of 14.4% and finally the increasing potential evapotranspiration,with a contribution rate of -27.7%.…”

Research on Impacts of Climate Change and Human Activitieson Runoff in the Yiluo River Based on SWAT Model by LIU Lyuliu, WANG Xiujie, ZHANG Pengfei

“…Affected by climate change and human activities, observed annual runoff during 1986 to 2015 decreased compared with that from 1971 to 1985. During the three periods of 1986—1995, 1996—2005 and 2006—2015, the relative contribution rate of climate change on annual runoff change was 68.7%, 22.5% and 83.1%respectively, that of human activities excluding LUCC was 30.9%, 76.7% and 16.9%respectively, while that of LUCC was less than 1%. …”

Okapi et Astrapi: précurseurs inattendus de la bande dessinée alternative ? by Maël Rannou

“…Porté par un fort rapport à l’image, la structure tente, après 1968, de renouveler son offre avec des propositions plus modernes et tournées vers les élèves de fin d’élémentaire et de collège, dans la continuité de sa création Pomme d’Api. Okapi, créé en 1971, puis Astrapi, créé en 1978, occupent cet espace et proposent des contenus parfois inattendus pour ce type de presse, naviguant entre classicisme édifiant et innovations. …”
