Research on Medium and Long-Term Runoff Forecast of Xijiang River in Dry Season Based on Statistical Model by LAN Yuxi, ZHANG Yin, NONG Zhenchang, WEI Yongjiang

“…Accurate medium and long-term runoff forecast is of great guiding significance to the development and utilization of water resources,allocation optimization,and water dispatch.Based on the three statistical models of mean generating function,periodic analysis,and multiple stepwise regression,this paper studied the medium and long-term runoff forecast of the Longtan Reservoir in the upper reaches of the Xijiang River and the Wuzhou hydrological station in the lower reaches from October to March of the following year and during the entire dry season (six months,from October to March of the following year).The results show that the three models all present positive forecast results.In the calibration and verification periods,the average pass rate exceeds 75%,and the mean absolute percentage error is basically within 30%.The forecast accuracy of the mean generating function and the multiple stepwise regression is significantly higher than that of the periodic analysis,with smaller forecast errors in larger values.Multiple stepwise regression is more stable than the other two models.Furthermore,affected by the consistency of data,the forecast accuracy of the Longtan Reservoir is significantly higher than that of the Wuzhou hydrological station.On the whole,multiple stepwise regression has the optimal forecast effect in the Xijiang River Basin.In addition,it can maintain high forecast accuracy at all levels and stages and provide a valuable reference for water dispatch decisions in the basin.In the future,multi-model fusion can be used to further improve the forecast effect.…”

VFSMOD-based Simulation and Analysis of Sediment Retention Effect of Vegetative Filter Strip by ZHANG Yuyang, SUN Zheng, CAI Guoqiang, NIE Shihao, ZHANG Liang, ZONG Quanli

“…Taking four typical vegetative filter strips in the Beichahe Village section,Renzhao Town sluice section,Chengjiaxiaoli Village section,and Houlujia Village section in the Dagu River Basin of Shandong Province as examples,this paper simulates the sediment retention effect with the vegetative filter strip model (VFSMOD).VFSMOD is applied to examine the sensitivity of the width,length,slope,vegetation spacing,and vegetation roughness of the vegetative filter strips to the sediment retention effect and compare the sensitivity of sediment retention rate to the five parameters in four typical locations. …”

Analysis of Evolution of the Wetland Ecosystem of the Liaohe River Nature Reserve over the Past 40 Years and Its Driving Factors by SUN Xiangru, CHEN Jiabo, WANG Yanjie

“…The wetland in the Liaohe River Nature Reserve has played a crucial role in pollutant purification and biodiversity protection for the Liaohe River Basin.This paper reviews the evolution of the wetland ecosystem of the Liaohe River Nature Reserve over the past 40 years and analyzes the major factors driving the process,and puts forward measures for wetland conservation and prospects for future research.The results show that:From 1980 to 2010,the total wetland area showed a decrease trend.Except for the protected area at the estuary of the Liaohe River,the Liaohe River Nature Reserve suffered scarce plant resources and extremely low diversity of plant species,making it unsuitable to serve as a breeding habitat for most birds and fishes.From 2010 to 2020,with the rapid recovery in wetland area,the macro plant structure and diversity improved significantly,resulting in a substantial increase in bird and fish populations.Major natural factors driving the changes of wetland include temperature and precipitation,while human factors such as agricultural development,water project construction,oil and gas exploration,urbanization,and exotic species invasion play a central role in the process.Currently,key measures such as strictly guaranteeing ecological water demand,re-planting aquatic vegetation in land-water cross bedding and open water areas,and conducting integrated control of exotic species invasion through physico-chemical and ecological prevention measures should be taken to promote wetland conservation.The future research should focus on wetland developmental mechanism of the Liaohe River Nature Reserve based on the basin scale.…”
