ABSTRACT
The Yellow River basin is a key region to study carbon peaking and carbon neutralisation owing
to its high ecological and economic importance in China. To achieve this dual carbon goal, the
relationship between carbon emissions and anthropogenic factors, such as urban land use, night light
intensity, population density, and urban economic activities, should be elucidated. This study aimed
to understand how urban construction land, urban economic activity intensity, and spatial population
density patterns impact the CO2 concentrations in the Yellow River basin using remote sensing data,
and how urbanisation impacts the ecological environment of the basin with respect to land, economy,
and population. The remote sensing satellite observation data was processed and subjected to coupling
analysis, spatial analysis, and spatial econometric model. We found that during the study period, the
lower reaches of the Yellow River basin exhibited a clear shift from construction to non-construction
land, whereas the middle and upper reaches showed the reverse trend. Moreover, the bivariate clustering
spatial patterns of construction land, night light intensity, and population with CO2 concentration values
had some similarities and partial differences. The coupling area of population and night light with
CO2 concentration was concentrated in the downstream, midstream, and upstream traffic trunk areas,
and the construction land strongly impacted some areas in the upstream and midstream regions. The
coupling and coordination of CO2 concentration, construction land, and -economic activity intensity of
cities in the Yellow River basin showed a ladder-like spatial pattern of increasing coordination degree
from upstream to downstream. Furthermore, the ecological environment in the study area was affected
by economic as well as population urbanisation. Urban construction land is one of the reasons for
the CO2 concentration in the Yellow River basin. This study suggests that high-quality development
should be focused on ensuring regional economic development and ecological environment security according to the different directions of the impact of urbanisation and industrialisation on the ecological
environment in different regions.
