Shared bicycles are currently widely welcomed by the public due to their flexibility and convenience; they also help reduce chemical emissions improve health encouraging people engage in physical activities. However, during development process, imbalance between supply demand of shared has restricted public's willingness use them. Thus, it is necessary forecast for different urban regions. This article presents a prediction model called QPSO-LSTM origin destination (OD) distribution combining long short-term memory (LSTM) quantum particle swarm optimization (QPSO). LSTM special type recurrent neural network (RNN) that solves long-term dependence problem existing general RNN, suitable processing predicting important events with very intervals delays time series. QPSO an intelligence algorithm simulating process birds searching food. In model, applied predict OD numbers. used optimize involving large number hyperparameters, optimal combination hyperparameters quickly determined. Taking Nanjing as example, two typical areas, needed per hour future day predicted. can effectively learn cycle regularity change bicycle quantity. Finally, compared autoregressive integrated moving average (ARIMA), back propagation (BP), networks (RNNs). shows result more accurate.

Public summary•What does AI bring to geoscience? has been accelerating and deepening our understanding of Earth Systems in an unprecedented way, including the atmosphere, lithosphere, hydrosphere, cryosphere, biosphere, anthroposphere interactions between spheres.•What are noteworthy challenges As we embrace huge potential geoscience, several arise reliability interpretability, ethical issues, data security, high demand cost.•What is future The synergy traditional principles modern AI-driven techniques holds immense promise will shape trajectory geoscience upcoming years.AbstractThis paper explores evolution geoscientific inquiry, tracing progression from physics-based models data-driven approaches facilitated by significant advancements artificial intelligence (AI) collection techniques. Traditional models, which grounded physical numerical frameworks, provide robust explanations explicitly reconstructing underlying processes. However, their limitations comprehensively capturing Earth's complexities uncertainties pose optimization real-world applicability. In contrast, contemporary particularly those utilizing machine learning (ML) deep (DL), leverage extensive glean insights without requiring exhaustive theoretical knowledge. ML have shown addressing science-related questions. Nevertheless, such as scarcity, computational demands, privacy concerns, "black-box" nature hinder seamless integration into geoscience. methodologies hybrid presents alternative paradigm. These incorporate domain knowledge guide methodologies, demonstrate enhanced efficiency performance with reduced training requirements. This review provides a comprehensive overview research paradigms, emphasizing untapped opportunities at intersection advanced It examines major showcases advances large-scale discusses prospects that landscape outlines dynamic field ripe possibilities, poised unlock new understandings further advance exploration.Graphical abstract

The concept of Digital Earth (DE) was formalized by Al Gore in 1998. At that time the technologies needed for its implementation were an embryonic stage and quite visionary. Since then digital have progressed significantly their speed pervasiveness generated are still causing transformation our society. This creates new opportunities challenges realization DE. ‘What is DE today?’, could be future?’, to make a reality?’. To answer these questions it necessary examine considering all technological, scientific, social, economic aspects, but also bearing mind principles inspired formulation. By understanding lessons learned from past, becomes possible identify remaining scientific technological challenges, actions achieve ultimate goal ‘Digital all’. article reviews evolution vision multiple definitions, illustrates what has been achieved so far, explains impact transformation, vision, concludes with future scenarios recommended facilitate full implementation.

Sustainable development goals (SDGs) in the United Nations 2030 Agenda call for action by all nations to promote economic prosperity while protecting planet. Projection of future land-use change under SDG scenarios is a new attempt scientifically achieve SDGs. Herein, we proposed four scenario assumptions based on SDGs, including sustainable economy (ECO), grain (GRA), environment (ENV), and reference (REF) scenarios. We forecasted along Silk Road (resolution: 300 m) compared impacts urban expansion forest conversion terrestrial carbon pools. There were significant differences land use stocks, scenarios, 2030. In ENV scenario, trend decreasing was mitigated, stocks China increased approximately 0.60% 2020. GRA rate cultivated area has slowed down. Cultivated South Southeast Asia only shows an increasing it other The ECO showed highest losses associated with expansion. study enhances our understanding how SDGs can contribute mitigate environmental degradation via accurate simulations that be applied global scale.

Geographic simulation models can be used to explore and better understand the geographical environment. Recent advances in geographic socio-environmental research have led a dramatic increase number of for this purpose. Some model repositories provide opportunities users apply models, but few general evaluation method assessing applicability recognition models. In study, an academic impact is proposed. Five indices are designed based on their pertinence. The analytical hierarchy process calculate index weights, impacts quantified with weighted sum method. time range controlled evaluate life-term annual that met criteria from different domains then evaluated. results show proposed method, major areas identified.
