摘要
“黄河流域生态保护和高质量发展”的国家重大战略地位进一步提升,土壤侵蚀引发的粮食安全与生态安全问题备受关注,评估土壤风蚀时空演变过程对于改善区域生态环境和可持续发展具有重要的科学意义。本数据集包含黄河流域2000-2018年逐年土壤风蚀模数数据集,采用地面调查与修正土壤风蚀方程(RWEQ)相结合的方法,综合考虑土壤风蚀中各影响因子,进行数据本地化,并结合植被因子测度黄河流域土壤风蚀量。数据基于137Cs调查对评估结果进行了验证,结果表明模拟结果与地面调查结果显著相关。本数据可反映黄河流域2000年以来土壤风蚀时空格局,用于区域土地退化动态评估、生态工程措施成效评价等方面。
The national strategy of“Ecological Protection and High-quality Development of the Yellow River Basin”has gained increased prominence,with growing attention on food security and ecological security caused by soil erosion.It is of great scientific significance to evaluate the temporal and spatial evolution of soil wind erosion for improving the regional ecological environment and promoting sustainable development.This dataset compiles the data on the annual soil wind erosion modulus in the Yellow River Basin from 2000 to 2018.In this study,we combined ground investigation with revised soil wind erosion equation(RWEQ)to measure the soil wind erosion.We have comprehensively considered various factors influencing soil wind erosion,localized the data,and measured the amount of soil wind erosion in the Yellow River Basin in combination with vegetation factors.The assessment results have been validated based on the 137Cs survey,demonstrating a significant correlation between the simulation results and the field survey data.This dataset captures the temporal and spatial changes of soil wind erosion in the Yellow River Basin since 2000.It can offer insights into regional land degradation dynamics and the evaluation of the effectiveness of ecological engineering measures.
