黄河流域黄土高原地区水土流失动态变化及分布特征
Dynamic changes and distribution characteristics of soil and water loss in Loess Plateau area of Yellow River Basin
摘要
Abstract
[Objective]This study aims to explore the dynamic changes of soil and water loss in the Loess Plateau area of the Yellow River Basin,understand the distribution characteristics of soil and water loss,and provide a reference basis for comprehensive management of regional soil and water loss.[Methods]Based on the national soil erosion remote sensing survey results and national soil and water loss dynamic monitoring outcomes,this study summarized and formed the distribution characteristics and dynamic changes of soil and water loss in the Loess Plateau Area.[Results]In 2021,the area of soil and water loss was 231 300 km2,accounting for 89.13%of the total soil and water loss in the Yellow River Basin.The distribution of soil and water loss was mainly concentrated in the sandy areas of the middle reaches of the Yellow River and the northern windblown sand areas,where the soil and water loss accounted for 51.06%of the soil and water loss area in the Loess Plateau area.In terms of land use type,soil and water loss was mainly distributed in grasslands,forests,and farmland,accounting for 86.80%.Compared with 2020,2011,1999,and 1985,the soil and water loss in 2021 decreased by 2 900 km2,34 300 km2,169 400 km2,and 223 000 km2,respectively.Compared with 1985,the area of soil and water loss with severe or higher intensity levels decreased by 164 200 km2,a decrease of 83.84%.[Conclusion]The Loess Plateau area of the Yellow River Basin is the main source of soil and water loss in the Yellow River Basin.Soil and water loss is mainly concentrated in the sandy areas of the middle reaches of the Yellow River and the northern windblown sand areas.The reduction of high-intensity erosion is related to the fact that the annual monitoring outcomes do not consider channel erosion.This area should be based on the watershed system as a unit,continuously strengthen the construction of dryland terraces,vigorously promote the construction of high-standard silt dams,enhance the reinforcement of dangerous silt dams,and implement the ditch consolidation and plateau protection project.关键词
