在作物收获之后,作物残留物还田可为防止土壤表面的水蚀和风蚀提供屏障,也有助于改善土壤结构,增加土壤中有机质的含量。因此,农作物残留物的管理是许多保护性耕作体系中的一个重要组成部分,被广泛应用到农业领域。目前对作物残留物的估算主要集中在遥感影像数据的光谱特征信息,而利用遥感影像的纹理特征信息、光谱特
After the crop is harvested, crop residues can provide a barrier to water erosion and wind erosion on the soil surface, as well as improve the soil structure and increase the amount of organic matter in the soil. Therefore, the management of crop residues is an important part of many conservation tillage systems and is widely used in agriculture. At present, the estimation of crop residue mainly focuses on the spectral feature information of remote sensing image data. However, using the texture feature information of remote sensing image,
