摘要：

卫星遥感在秸秆覆盖度估算及保护性耕作方式落实情况评估方面具有广泛应用。本研究以吉林梨树县为研究区，对研究区内2020—2024月际间、年际间秸秆覆盖情况进行反演。结果表明：历年秋收后（10月末）至春播前（4月初），全县秸秆覆盖度持续降低，低覆盖区域明显增大，且年际间差异明显。基于耕作指数反演后的梨树县玉米秸秆覆盖动态变化分析可精细化掌握秸秆资源的时空分布，合理监督黑土地保护性耕作情况。

Abstract:

Satellite remote sensing has a wide range of applications in estimating corn residue cover and evaluating the implementation of conservation tillage methods. This study took Lishu County, Jilin Province as the study area to invert the inter-monthly and inter-annual straw coverage conditions from 2020 to 2024. The results showed that from the end of autumn harvest (late October) to the beginning of spring sowing (early April), the straw coverage rate in the whole county continued to decrease, and the low coverage areas significantly increased, and the inter-annual differences were significant. The dynamic change analysis of straw coverage in Lishu County based on the inversion of tillage index could accurately indicate the spatial and temporal distribution of straw coverage and give insights to the protective tillage practices of black soil.

Key words: straw coverage rate, conservation tillage, tillage index, remote sensing inversion, dynamic changes, Lishu County
