摘要
水土流失动态监测是水土保持监测的主要内容,能够为水土保持工作提供数据支撑,为水土流失治理指明方向.通过对潼关县2020年～2022年全国水土流失动态监测成果数据统计对比,分析潼关县水土流失年度变化情况.结果表明:潼关县水土保持率逐年提高,土壤侵蚀强度为强烈及以上的等级面积在逐年降低,高侵蚀强度等级逐渐转化为低侵蚀强度等级,生态环境正持续向好.
Abstract
Dynamic monitoring of soil and water loss is the main content of soil and water conservation monitoring,which can provide data support for soil and water conservation work and point out the direction for soil and water loss control.Through the statistical comparison of the dynamic monitoring results of soil and water loss in Tongguan County from 2020 to 2022,the annual change of soil and water loss in Tongguan County was analyzed.The results showed that the soil and water conservation rate in Tongguan County increased year by year,the area of strong soil erosion intensity and above decreased year by year,the high erosion intensity grade gradually transformed into low erosion intensity grade,and the ecological environment was continuously improving.
