Evaluation of Sustainable Utilization of Water Resources and Soil and Water Conservation Regulation in the Laoguan River Basin
The middle reaches of Laoguan River is an important water conservation area of Danjiangkou Reservoir.Its sustainable utilization of water resources plays a huge role in the stable operation of the South-to-North Water Diversion Project.In this study,the Ecological footprint method and Pearson correlation coefficient method were used to quantitatively evaluate the sustainable use of water resources and impact factors in the middle reaches of the Laoguan River,and then targeted control measures for water and soil conservation were proposed.The results show that between 2006 and 2020,the surplus years of water resources in the middle reaches of the Laoguan River accounted for about 86.67％of the total years,and the sustainable utilization status of water resources in the middle reaches of the Laoguan River was good;Retaining soil and water resources is a key measure for the sustainable utilization of water resources in the region.
