2019年~2020年扶风县水土流失动态变化分析

Analysis of Dynamic Changes in Soil and Water Loss in Fufeng County from 2019 to 2020

以陕西省省级水土流失动态监测区的扶风县为例,对2019年及2020年动态监测数据进行对比分析,得到该县年度间水土流失动态变化成果。结果表明,2020年水土流失面积为73.76km^(2),与2019年相比减少了0.96km^(2);中高植被覆盖度区域面积显著增加;各主要土地利用类型侵蚀强度等级降低,土壤侵蚀面积减小,生态环境向好发展。

Taking Fufeng County,a provincial-level dynamic monitoring area for soil and water loss in Shaanxi Province,as an example,a comparative analysis was conducted on the dynamic monitoring data from 2019 to 2020,and the results of the annual dynamic changes in soil and water loss in the county were obtained.The results show that the area of soil erosion in 2020 was 73.76 km^(2),a decrease of 0.96 km^(2)compared to 2019;The area with medium to high vegetation coverage has significantly increased;The erosion intensity grade of each major land use type is reduced,the soil erosion area is reduced,and the ecological environment is developing better.
