High spatial resolution mapping of steel resources accumulated above ground in mainland China: Past trends and future prospects

High-resolution mapping of steel resources accumulated above ground (referred to as steel stocks) is critical for exploring urban mining and circular economy opportunities. Prior studies have attempted to approximate steel stocks using nighttime …

The Evaluation of Health Effect of Short-term Exposure to PM2.5 during Spring Festival: A Case Study of 25 Cities in the Yangtze River Delta(Chinese)

Using Tencent location based service data and machine learning mapping produced by multi-sources geospatial data to investigate the health risk of short-term exposure to PM2.5..

Investigating the Uncertainties Propagation Analysis of CO$_2$ Emissions Gridded Maps at the Urban Scale: A Case Study of Jinjiang City, China

Cities play an essential role in low-carbon development. However, Estimating CO$_2$ emissions at the urban scale, including both un-gridded (i.e., administrative unit maps) and gridded maps, cannot avoid the propagation of uncertainties from input to result, which highlights the importance of being aware of uncertainty estimation, especially in gridded maps due to its implications for the precision mitigation of CO$_2$ emissions. We proposed an analytic workflow to analyze the propagated uncertainties caused by the gridded model and the input for gridded CO$_2$ emission maps.

What is geography? From coronavirus disease 2019 to Bei Dou Systems

We just want to talk about what is geography and three laws of geography.

A spatial database of CO$_2$ emissions, urban form fragmentation and city-scale effect related impact factors for the low carbon urban system in Jinjiang city, China

This paper presented the spatial database collected in 2013 for mitigating the urban carbon emissions of Jinjiang city, China. The database included the high-resolution $CO_2$ emissions gridded maps, urban form fragmentation evaluation maps, and …

Spatial Lifecourse Epidemiology

Spatial Lifecourse Epidemiology was proposed by my supervisor, Dr.Jia Peng. This is the basic theory of My PhD project.

More fragmentized urban form more CO$_2$ emissions? A comprehensive relationship from the combination analysis across different scales

The “Scale effect” has always been the hot topic in landscape ecology research. Although, there are many studies on the driving force of urban environmental problems by using landscape metrics. Most studies are carried out in regional, continental and global scales. However, in this study, we explored the relationship between the urban form fragmentation and $CO_2$ emissions in the city scale from the perspective of dual resolution sizes and summarized the research conclusions that can be used in urban internal management based on the analysis results of small towns.

The impacts of climate and land use/land cover changes on water yield service in Ningbo region(Chinese)

Providing water resources is one of the most important ecosystem services functions and plays an important role in the sustainable development of regional economy and ecosystem. In recent years, the increased demand for water resources, water …

Creating a Carbon Source and Sink Map by Coupling an Ecological Process Model with an Emission Inventory to Study a Carbon Balance

Cities are typical sources of carbon and a focus of climate-change mitigation. Although there is great potential for reducing emissions in cities, constructing low-carbonemission cities under the carbon-emission reduction target of the 2016 Paris …
