Study on the Annual Variation Characteristics of Runoff in Yunnan by GU Guihua, LI Xuehui, YU Shoulong, DUAN Lusong

“…To study the annual variation characteristics of runoff in Yunnan Province and analyze the main influencing factors,based on the observed monthly and annual rainfall and runoff data of 9 representative hydrological stations in 6 major river basins in Yunnan from 1956 to 2016,this paper analyzes the annual runoff distribution in terms of the uniformity,concentration and relative variation range.The research shows that:①The uniformity coefficient (C_u) of runoff distribution in many years ranges from 0.55 to 1.21,and the concentration (C_n) ranges from 0.23 to 0.66,so the runoff is unevenly distributed in the whole province.②The C_u and C_n decrease in general.Especially after 2000,the annual distribution of runoff shows a trend of uniformity.③The runoff concentration is relatively high in the Yangtze River Basin and the Honghe River Basin,and the annual runoff distribution is flat in the Lancang River Basin and the Zhujiang River Basin.④The uniformity trend of annual runoff distribution is closely related to human activities in the basin.…”

Evaluation of Ecological Water Conservancy Benefits for Lakeside Cities Based on Principal Component Analysis by GU Xiaohan, ZHU Shijie, MAO Jinqiao

“…Lakeside cities are important intersection areas of natural land,lakes and urban ecology.Poyang Lake plays an important role in regulating the water level of the Yangtze River,conserving water resources,improving local climate and maintaining water security.In order to objectively and comprehensively measure the ecological water conservancy benefits of the lakeside cities around the Poyang Lake,taking the Gongqingcheng City as a typical case and the statistical analysis as a basis,this paper puts forward the evaluation index system qualitatively and quantitatively from three aspects of economic benefits,social benefits and ecological benefits,and constructs the evaluation model by the principal component analysis method.The results show that the score of ecological water conservancy benefits of the Gongqingcheng City in 2019 is 1.253 8,the ecological quality grade is Class III,the regional economy is well developed,and the ecological and social benefits are remarkable,which are consistent with the current ecological status of the Gongqingcheng City.Therefore,the model is featured with good applicability and rationality.…”

Impact of Labour Productivity Differences on Urban-Rural Integration Development and Its Spatial Effect: Evidence from a Spatial Durbin Model by Wei Wang, Yulin Zhu

“…The results show that there is a significant positive spatial agglomeration phenomenon in urban-rural integration in the Yangtze River Economic Belt. The convergence of labour productivity will not only promote local urban-rural integration but also inhibit the urban-rural integration development of other administrative divisions, but it can still play a positive role in promoting the urban–rural integration development of the whole region. …”
