Analysis of Evolution of the Wetland Ecosystem of the Liaohe River Nature Reserve over the Past 40 Years and Its Driving Factors
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.…”

De l’Esthétisation à l’anti-symbolisme : les évolutions du corps chez William Carlos Williams
Published 2023-06-01“…Nevertheless, at the end of the 1930s, the body is re-naturalized as Williams witnesses the physical degradation of his dying mother; he thus represents the vulnerability of the body in his poems, the textual body freezing in time the fleeting evolutions of the physical body. Therefore, the passage from aestheticized to anti-symbolic bodies in Williams’ work is based on both the stylistic and biographical evolutions of the author, making his writing the mirror of the living and evolving bodies of his period.…”
