Study on Spatiotemporal Distribution Characteristics of Rainfall Erosivity in “Three-Lake” Basin of Central Yunnan by YANG Wenchun, GU Guihua, ZHU Weibing, HUO Shouhua

“…This study is conducted to explore the influence of rainfall on the characteristics of soil erosion in the “three-lake” basin of Fuxian Lake,Xingyun Lake,and Qilu Lake in central Yunnan.On the basis of the daily rainfall observation data of four precipitation stations in the basin from 1992 to 2020,namely,the Liangwanghe,Haikou,Chaershan,and Shagouzui Stations,the daily rainfall erosivity model is employed to calculate rainfall erosivity.Then,its temporal variation characteristics are analyzed with the M-K method,and the spatial changing laws of rainfall and rainfall erosivity are investigated by the Kriging interpolation method for spatial interpolation.The results are as follows:From 1992 to 2020,the average annual rainfall in the “three-lake” basin is 907.6 mm,and the average annual rainfall erosivity is 3 088~4 172 MJ·mm/(hm²·h);the variation coefficient of annual rainfall erosivity is between 0.25 and 0.32,and the number of days with erosive rainfall at each station is 686~759.There is a good correlation between annual rainfall and annual rainfall erosivity,and the annual rainfall erosivity in the basin fluctuates on the whole,with no significant increasing trend and no abrupt change.The rainfall erosivity varies significantly within the year,with that in summer accounting for 61.4% and that in the flood season accounting for 90.5% of the year,and the variation of rainfall erosivity is topped by summer,followed by autumn,spring,and winter.The spatial distribution trend of average annual rainfall erosivity in the basin is consistent with the annual rainfall distribution trend,high in the north and low in the south.The rainfall erosivity decreases gradually from north to south in terms of years,flood seasons,summer,and autumn,while in terms of non-flood seasons,spring,and winter,rainfall erosivity decreases from northeast to southwest.The research results can provide a scientific basis for water and soil conservation and ecological protection of lakes in the basin of plateau lakes in central Yunnan.…”

Study on Spatial-temporal Characteristics of Drought Duration and Intensity in Leizhou Peninsula in Recent 50 Years by DU Xiaoxia, TU Xinjun, XIE Yuting, WANG Tian

“…In the background of global warming,drought disasters occur frequently,bringing serious impacts on the natural ecosystem,human production and life and social & economic development.Therefore,it is of great significance to analyze and assess regional drought characteristics and study local drought mitigation and disaster reduction decisions and climate change.Based on the meteorological and hydrological data of 12 sites in Leizhou Peninsula from 1970 to 2019,this paper identifies and evaluates the drought events via standardised precipitation-evapotranspiration index (SPEI) and run theory,and analyzes the temporal and spatial variation characteristics of drought duration and intensity in Leizhou Peninsula in recent 50 years combined with curve fitting method,inverse distance weighted spatial interpolation,etc.The results show that:①The monthly SPEI index of the Leizhou Peninsula in recent 50 years showed a decreasing trend in fluctuation.On the time scale of the recent 50 years,it fluctuated with a period of about 10 years,which is related to the influence of ENSO.The SPEI is relatively high in cold event years,on the contrary,in warm event years,the SPEI is low and the drought is serious.②The greater the intensity of drought disaster in Leizhou Peninsula,the smaller the probability.③Due to regional difference,the spatial distribution of drought frequency,intensity and duration showed a gradually increase trend from the northeast to the southwest.④The regional difference of the occurrence frequency of drought of different grades showed that the frequency of moderate drought and above in the central and southern and northeastern regions of Leizhou Peninsula was higher than that in the central and northern regions.In addition,the drought in the southern part of Leizhou and Xuwen County was severe.⑤Droughts occur frequently in spring and winter.In spring and summer,the drought in the northeast and central-south part of the Leizhou Peninsula was more severe,the drought in autumn was more serious in the central-north part of the peninsula,and the drought in winter seriously affected the central-south part of the peninsula.…”
