    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

    Published 2021-01-01
    “…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.…”

    Research on Water Quality Improvement Method Based on Slowly-Stored and Quickly-Released System in Xi'an Moat by SUN Chao, HAN Weigang, NONG Xiaoying, WANG Hui, WANG Wenyu, GAO Zehai

    Published 2023-01-01
    “…The slowly-stored and quickly-released system was studied to explore the method of optimizing the hydrodynamic force of rivers in arid regions and reveal its effect on water quality.The south-west tributary of Xi'an moat was defined as the study area.A hydrodynamic force-water quality coupling model of the moat was built based on the collected data of current water quality and hydrodynamic force by using MIKE21.In the coupling model,the impounding gate was designed based on the dam body of the moat to simulate the scouring and silting capacity of the lower reaches caused by rapid discharge from the upper reaches of the channel.The influence law of rapid discharge at different water levels and water quality conditions on hydrodynamics and water quality of the moat was studied.The numerical simulation results from MIKE21 show that water level has a significant influence on the hydrodynamic force,and water quality has a significant influence on the pollutant concentration.The simulation results of the hydrodynamic force-water quality coupling model of the moat show that the working condition with a 1-meter water level and class Ⅲ inlet water quality can greatly improve the water quality and hydrodynamic force of Xi'an moat.By using the water reaching the standard of the class Ⅲ inlet water quality as the supply source,the water quality of Xi'an moat can be effectively improved by enhancing the hydrodynamic force of the moat.…”
