石羊河流域水文与水资源特征及其对沙漠化影响
Characteristics of hydrological and water resources in the Shiyang River Basin and their effects on land desertification
摘要
Abstract
In this article,using the parameters of hydrological,water resources,and the desertification area of the Shiyang River basin in different periods,the basin hydrology,water resources,desertification,and its changes in the relationship between them were quantitatively studied.It provides the data and the theoretical basis for hydrological,water resource features,and land desertification in this area.The research showed that although the precipitation in the Shiyang River basin had increased from 2005 to 2021,the variability was large and remained at a low level,with an average annual precipitation of only 234.70 mm.From 1993-2004,the annual precipitation at the Caiqi hydrological station reduced,whereas the annual sediment transport increased.The annual precipitation at the Zamusi hydrological station increased from 1999 to 2021,whereas the annual sediment discharge decreased.From 2005 to 2021,the total amount of water resources in the Shiyang River basin decreased by 0.24×108 m3·a-1,but water consumption and water consumption remained at high levels of 24.70×108 m3 and 17.07×108 m3,with high water consumption and consumption in agriculture,forestry,and fruit industries,exacerbating the irrationality of water resource utilization in the basin.From 1975 to 2014,the total area of desertified land in the basin reduced,but the land changes in different periods and desertification types remained quite different,and the situation of desertification prevention and control in the basin was still grim.关键词
