Analysis and evaluation of the ecological improvement of Taitema Lake by ecological water transport
[Objective]The aims of this study are to evaluate the ecological environment improvement status of the affected area after the ecological water transfer of Lake Taitema,and to provide support for regional vegetation construction,soil erosion control,and lake ecological restoration.[Methods]Based on the dynamic monitoring results of soil erosion nationwide,a comparative analysis was conducted on the changes in land use and corresponding soil erosion in the Taitema Lake Basin before(1998)and in the current year(2022)of ecological water transfer.[Results]Compared with before ecological water transfer,the sandy area in the water affected area of Lake Taitema decreased by 454.79 km2,with a decrease rate of 70.79％.The vegetation area increased by 304.30 km2,with a growth rate of 100.24％.The vegetation coverage increased from 14.83％before ecological water supply to 22.26％.The area affected by ecological water transportation in Lake Taitema had decreased by 437.51 km2 to 254.60 km2,accounting for 25.18％of the total land area,all of which were mild erosion.The area of soil erosion had decreased by 437.51 km2.[Conclusion]After ecological water transfer,the ecological environment of Lake Taitema had significantly improved,and the regional land use had shifted from a single structure dominated by sandy land to a diverse structure,with a significant increase in vegetation coverage.
