应用于水旱灾害防御的土壤墒情等级划分探析OA
Analysis of soil moisture classification applied to water and drought disaster prevention work
土壤墒情是防汛抗旱和山洪灾害防御的重要基础参数.通过调研水利、农业、气象及地方的墒情规范标准,结合水旱灾害防御的工作要求,基于土壤相对湿度对土壤墒情进行科学分级,创新性地将其划分为特大干旱、严重干旱、中度干旱、轻度干旱、适墒、偏湿、基本饱和共7个等级,并以北京市为例,通过对比分析2024年降水和墒情变化特征,选取非汛期和汛期代表时点进行了墒情分级评价,此墒情划分成果和应用研究对墒情分析评价和其他地区的防洪抗旱工作具有借鉴作用.
By reviewing the standards and norms for soil moisture in water conservancy,agriculture,meteorology,and local regulations,and aligning with the requirements for drought and flood disaster prevention,the study scientifically categorizes soil moisture based on relative soil humidity.It innovatively divides soil moisture into seven levels:extreme drought,severe drought,moderate drought,mild drought,optimal moisture,slightly wet,and nearly saturated.Using Beijing as a case study,the research compares and analyzes precipitation and soil moisture changes in 2024,selecting representative periods during non-flood and flood seasons for moisture classification evaluation.The findings and applied research on soil moisture classification provide valuable references for soil moisture analysis,evaluation,and flood and drought prevention efforts in other regions.
