Speech Title: Structural Resilience Evolution of Global Oil and Gas Resource Trade Network

Abstract: The security and stability of the oil and gas resource trade network are crucial to national energy security and support social and economic development. This paper analyzes the evolution of the global oil and gas resource trade network structural resilience in 2010, 2015, and 2020 and establishes a network resilience evaluation framework according to the network structure, simulated attacks and identified chokepoints to make an integrated analysis of the structural resilience of the global oil and gas resource trade network. The results are as follows: The links of global oil trade network presents a gradually shrinking trend, and the natural gas trade network presents a trend of close connection first and then reduced connection. In terms of network density, network centrality, network connectivity and network size, the structural resilience of the oil and gas resource trade network displays a gradually shrinking trend, and the natural gas trade network is superior to the oil trade network. With regard to the invulnerability and recovery, the resilience of the oil trade network is superior to the natural gas trade network. In simulated attacks, the oil trade network reveals a higher resilience towards intentional attacks, and the natural gas trade network shows a higher resilience towards random attacks. The Strait of Hormuz and the Strait of Malacca are extremely important chokepoints in the oil and gas trade network. The results are able to provide reference and decision-making support for route design, optimization and lay the foundation for establishing a secure maritime transport system for resources.

Speech Title: Simulating Block-Level Urban Expansion for National Wide Cities

Abstract: Large-scale models are generally associated with large spatial modelling units, for example, counties or super grids (several to dozens of km2). Few applied urban models can achieve a large spatial coverage with irregular spatial units due to data availability and computation load. The framework of automatic identification and characterization of blocks developed by Liu and Long (2016) makes such an ideal model possible by establishing the existing urban blocks using road networks and points of interest for very large areas (e.g., a country or a continent). In this study, we develop a mega-vector-blocks cellular automata model (MVB-CA) to simulate urban expansion at the block level for 654 Chinese cities. The existing urban blocks in 2012 were used for initiating the MVB-CA and are generated using multi-levelled road networks and ubiquitous points of interest. We then simulate block-based urban expansion of all the cities from 2012 to 2017. The national spatial development strategies of China are discussed extensively by academia and policy makers, while the baseline scenario and other simulated urban expansion scenarios have been tested and compared horizontally. As one of the first block-based urban expansion models at a national scale, its academic contributions, practical applications, and potential biases are also discussed in this paper. The developed MVB-CA using general approaches is also applicable for other counties.

Speech Title: Regional Scale Coupling Between Climate and Forest Phenology and Their Hydrothermal Effects

Abstract: Climate warming is increasingly affecting ecological processes and biodiversity, with profound implications for ecosystem function and human well-being. As the main surface type of terrestrial ecosystem, forest growth, especially the phenological process of forest canopy structure, is not only directly affected by climate change, but also plays a key role in regional hydrothermal carbon and biological processes by absorbing CO2 and changing the hydrothermal interaction process with the atmosphere. Therefore, forest canopy is an important bridge between climate change and regional function. We using field observation and remote sensing data and model simulation method, focus on climate change and regional scale forest ecosystem the response and feedback of the series research, found that the climate of canopy structure (phonological process) control law and the spatial distribution pattern, illustrates the coupling mechanism between climate and canopy phenology; A forest microclimate assessment model based on vertical energy process was established, and the thresholds and latitude patterns of key structural parameters controlling forest increase and cooling were defined. Develop biophysical mechanisms for coupling forest hydrothermal effects and reveal thresholds for key climate parameters that weigh forest cooling and water resource effects.

Speech Title: Urban Landslides: Complex Approach to Observation Methods and Monitoring Results Analysis

Abstract: Landslides in urban regions are dangerous and unpredictable phenomena. Typically, the landslides in urban areas are complex objects that comprise the landslides themselves, engineering structures on them, and systems of retaining walls. The retaining walls are the most common way to protect buildings and infrastructure in large cities. These walls restrain the landslides' movements, save the structures on the landslides, and protect surrounding facilities and engineering infrastructure. Insofar as the retaining walls undergo extremely high pressure from the landslide's body, complex monitoring is an essential and responsible issue. Thus, the monitoring technology should include various geospatial methods to detect spatial displacements of the landslides, structures, and retaining walls. Obviously, such a technology cannot be based on one observation method. The aim of the presented research is twofold. The first is to suggest and develop a complex urban landslide monitoring approach that embraces different observation methods and their integration. The second is monitoring results analysis. That aim is more complicated as long as it needs to draw on the miscellaneous math models and algorithms. The monitoring results have to be analyzed with special attention due to the unpredictable nature of landslides. The considerable number of factors, e.g., environmental loads, transport effect, construction works, etc., makes the analysis complex and needs different methods. The complex approach to monitoring results analysis comprises statistical and structural mechanics methods. The suggested approach starts with a statistical analysis of observations. For processing, it was recommended to use the method of analysis of variance (ANOVA). Different factors and their relationship were investigated. The changes of displacements depending on the observation epoch were studied by one-factor ANOVA. One-factor ANOVA allowed defining that the deformation process has different dynamics for different retaining walls. The relationship between epoch and retaining walls placement was determined using two-factor ANOVA. Method three-factor ANOVA allowed defining the liaison between the locations of deformation targets and displacement values. The results of the ANOVA analysis gave a clear picture of the deformation process. However, some factors remained unaccounted for. Among those factors, the temperature variation of the retaining walls is significant. Therefore, this factor had to be eliminated from observation results before creating prediction models. The methods of structural mechanics were applied to manage the issue with the temperature variation. The simulation of the retaining walls showed the additional displacements, up to 5 mm due to temperature variation. These additional displacements were ruled out from measurements results before further analysis. The next stage of the complex analysis was about the determination of regions with uniform displacements. Another statistical procedure known as cluster analysis was applied to figure out these regions. Cluster analysis allowed identifying the regions for which the same prediction models can be used. The final step was the creation of prediction models for regions with uniform displacements. The modern algorithm known as the group method of data handling (GMDH) was examined. The method allows accounting for various factors in its model. Finally, the prediction model that accounts for displacements values, targets position, environmental effect, and observation accuracy was constructed. The considered above complex approach turned out highly efficient and allowed avoiding the wrong decision during landslides monitoring and carrying the protection measures.

Speech Title: Global impacts of future urban expansion on terrestrial biodiversity

Abstract: Rapid urban expansion has profound impacts on global biodiversity through habitat conversion, degradation, fragmentation, and species extinction. However, how future urban expansion will affect global biodiversity needs to be better understood. We contribute to filling this knowledge gap by combining spatially explicit projections of urban expansion under shared socioeconomic pathways (SSPs) with datasets on habitat and terrestrial biodiversity (amphibians, mammals, and birds). Overall, future urban expansion will lead to 11–33 million hectares of natural habitat loss by 2100 under the SSP scenarios and will disproportionately cause large natural habitat fragmentation. The urban expansion within the current key biodiversity priority areas is projected to be higher (e.g., 37–44% higher in the WWF’s Global 200) than the global average. Moreover, the urban land conversion will reduce local within-site species richness by 34% and species abundance by 52% per 1 km grid cell, and 7–9 species may be lost per 10 km cell. Our study suggests an urgent need to develop a sustainable urban development pathway to balance urban expansion and biodiversity conservation.

Speech Title: Spatial governance of street vendors based on social sensing and GeoAI.

Abstract: Eviction and formalization policies are widely joint used to govern street vendors in modern cities. However, the formalization schemes are at risk of failure due to they fail to respect the logic of street vending economic processes. Aiming at optimizing the geographical boundary between eviction and formalization policies, we present a model to delineate the formalization zones. The model first studies the spatial heterogeneity of location preferences of the street vendors based on city-scale detection data. Then a spatial optimization model was applied to seek an optimal formalization zoning scheme, taking into account the goals of location preferences, exclusive preferences, and administration cost. The case study results show that the sort and contribution of the influencing factors of the street vending location are different between the city core areas and peripheral areas. By introducing the social sensing data source and GeoAI technique, the presented model can portray the location preferences of the practitioners and delineate the scenarios formalization zones fully respect the appeals of the practitioner, the citizens, and the administration.
