Hilly and mountainous areas account for 69% of China’s land area and undertake critical agricultural production tasks, but the poor adaptability of mainstream intelligent agricultural machinery and inefficient promotion models have become key bottlenecks restricting agricultural modernization. This study’s core innovation lies in constructing a ``four-dimensional integrated solution'' (equipment lightweight improvement - dynamic control optimization - hybrid sharing promotion - farmland mechanization-friendly transformation) and quantifying the coupling mechanism between topographic constraints and agricultural machinery performance. By introducing plot shape coefficient and slope volati... More >

Apocynum venetum has clustered, highly branched stems with strong phloem fiber adhesion, which makes mechanical harvesting prone to entanglement, grip slippage, conveyance blockage, and uneven, high stubble. Existing cutting and bundling machines do not match this morphology well and cannot meet both low-stubble and anti-clogging requirements. To address these problems, an integrated Apocynum venetum cutting-bundling harvester was developed that combines a reciprocating cutting mechanism, stem-folding assembly, vertical anti-clogging conveyor at the cutting table, height-adjustable crop-plate compaction device, and cord-based bundling mechanism, which was supported by a combined navigation s...

Maize productivity in India, a major global producer, is severely threatened by leaf diseases. Accurate identification of Common Rust (CR), Northern Corn Leaf Blight (NCLB), and Gray Leaf Spot (GLS) remains challenging with traditional methods. This study evaluated traditional and ensemble-based classifiers for classifying these diseases alongside healthy (HL) leaves. Using accuracy, precision, recall, and F1-score, we assessed k-NN, DT, RF, ETs, AdaBoost, SGD, GB, XGBoost, LightGBM, and a Stacking model on a four-class dataset. Ensemble methods demonstrated clear superiority. The Stacking model achieved the highest accuracy (98.50%), followed by LightGBM (98.46%) and XGBoost (98.01%). Among... More >

Against the backdrop of the synergistic advancement of rural revitalization and agricultural modernization, optimizing the Production-Living-Ecological (PLE) spatial pattern and introducing digital-intelligent technologies have become key pathways for enhancing sustainable rural development capabilities. This study takes Ulanqab City in Inner Mongolia, a typical agro-pastoral ecotone, as a case study. Based on multi-source remote sensing image data from 2000 to 2020, it comprehensively utilizes a coupling coordination model and spatial information technology to evaluate the evolution characteristics of its PLE spaces and the coordination mechanisms of agricultural functions, supplemented by...

Ecosystem service valuation (ESV) provides a scientific basis for balancing ecological conservation and socioeconomic development. With the rapid progress of Earth observation technologies, remote sensing has become an essential tool for quantifying and mapping ecosystem services at multiple spatial and temporal scales. However, a comprehensive understanding of the global research landscape on ecosystem service valuation using remote sensing remains limited. In this study, this study conducted a bibliometric analysis of publications retrieved from the Web of Science Core Collection between 1990 and 2024. A total of 1172 articles were identified through a systematic search strategy integratin... More >
