Timely and accurate cropland information at large spatial scales can improve crop management support the government in decision making. Mapping extent distribution of crops on a scale is challenging work due to variability. A multi-task spatiotemporal deep learning model, named LSTM-MTL, was developed this study for large-scale rice mapping by utilizing time-series Sentinel-1 SAR data. The model showed reasonable classification accuracy major production areas U.S. (OA = 98.3%, F1 score...

Hydraulic residence time (HRT) distribution intuitively reflects flow pattern of constructed wetlands. HRT is able to reflect the merits state clearly. Short-circuiting and mixing are most important factors on HRT, exerting a significant effect These two conditions must be avoided in wetlands construction management. Therefore, it necessary select best indicators measuring short-circuiting for understanding hydraulic performance This paper analyzes numerous reflecting degree mixing,...

Abstract Environmental factors, including greenhouse gas (GHG) emissions and soil organic carbon (SOC), should be considered when building a sustainable biofuel supply chain. This work developed three‐step optimization approach integrating geographical information system‐based mixed‐integer linear programming model to economically optimize the chain on premise of meeting certain GHG emission criteria. The biomass grid cell was first, based maximum level emissions, prior economic...

<b>Abstract.</b> The cross-district transfer operation service of agricultural machinery in China is widespread. Harvest services the main wheat production areas (14 counties) were studied on basis ensuring timely harvest, a mixed integer linear programming model was constructed. Taking transport cost cooperatives minimization as objective function, decision variables such optimal allocation quantity and route to finish harvesting limited time window. scheduling (CDOSAM) solved by...
