Abstract

Purpose

Prediction of soil particle content is essential for soil texture classification, soil management and agricultural production. This study aimed to achieve high-accuracy predictions of soil particle content in the Ogan-Kucha River Oasis using hyperspectral data and environmental variables.

Materials and methods

We collected 62 representative surface soil samples (depth: 0–10 cm), and conducting indoor soil particle content and spectral measurements. The relationship between environmental variables and soil particle content was analyzed using the Boruta algorithm, and seven three-band spectral indices (TBIs) were constructed using an optimal band algorithm. By integrating environmental covariates and TBIs, soil particle inversion models were developed using the extreme learning machine (ELM), backpropagation neural networks (BP), neural networks optimized with the sparrow search algorithm (SSA-BP), and neural networks optimized with the sparrow search algorithm enhanced by Sine chaos mapping (Sine-SSA-BP).

Results and discussion

The results demonstrated that (1) the Boruta algorithm identified key environmental covariates that affect specific soil particle components; (2) there was significant variation in the correlation between different TBIs and soil particle content, with absolute correlation coefficients ranging from 0.225 to 0.852; (3) the estimation models established by the four machine learning algorithms performed well in predicting soil particle content, particularly for silt (R2: 0.664–0.858, RMSE: 11.107–17.128) and clay (R2: 0.444–0.857, RMSE: 0.550–1.405), for which higher accuracy was achieved; and (4) compared with the traditional ELM (R2: 0.422–0.664), BP (R2: 0.487–0.673) and SSA-BP models (R2: 0.625–0.777), the Sine-SSA-BP model showed a significant improvement in prediction accuracy, with the highest R2 reaching 0.858.

Conclusion

Compared to the traditional ELM, BP and SSA-BP models, the Sine-SSA-BP model significantly excelled in predicting soil particle content, offering innovative insights and robust support for soil texture classification and management.

提高土壤颗粒含量预测精度:先进的高光谱分析和机器学习模型
目的预测土壤颗粒含量对于土壤质地分类、土壤管理和农业生产至关重要。本研究旨在利用高光谱数据和环境变量对奥干-库车河绿洲的土壤颗粒含量进行高精度预测。材料与方法 我们采集了 62 个具有代表性的表层土壤样本(深度:0-10 厘米),并进行了室内土壤颗粒含量和光谱测量。使用 Boruta 算法分析了环境变量与土壤颗粒含量之间的关系,并使用最优波段算法构建了七个三波段光谱指数(TBI)。通过整合环境协变量和 TBI,利用极端学习机(ELM)、反向传播神经网络(BP)、利用麻雀搜索算法优化的神经网络(SSA-BP)以及利用正弦混沌映射增强的麻雀搜索算法优化的神经网络(Sine-SSA-BP)建立了土壤颗粒反演模型。结果与讨论结果表明:(1)Boruta 算法确定了影响特定土壤颗粒成分的关键环境协变量;(2)不同 TBI 与土壤颗粒含量之间的相关性存在显著差异,绝对相关系数从 0.225 到 0.852;(3)四种机器学习算法建立的估算模型在预测土壤颗粒含量方面表现良好,尤其是对淤泥(R2:0.664-0.858,RMSE:11.107-17.128)和粘土(R2:0.444-0.857,RMSE:0.550-1.405)的预测精度较高;(4)与传统的 ELM(R2:0.422-0.664)、BP(R2:0.487-0.结论与传统的 ELM、BP 和 SSA-BP 模型相比,Sine-SSA-BP 模型在预测土壤颗粒含量方面表现突出,为土壤质地分类和管理提供了创新见解和有力支持。

期刊介绍: The Journal of Soils and Sediments (JSS) is devoted to soils and sediments; it deals with contaminated, intact and disturbed soils and sediments. JSS explores both the common aspects and the differences between these two environmental compartments. Inter-linkages at the catchment scale and with the Earth’s system (inter-compartment) are an important topic in JSS. The range of research coverage includes the effects of disturbances and contamination; research, strategies and technologies for prediction, prevention, and protection; identification and characterization; treatment, remediation and reuse; risk assessment and management; creation and implementation of quality standards; international regulation and legislation.
