Dear BCL members and friends,

Three BCL members, Dr Ying Long, Dr Kang Wu and Dr Qizhi Mao, have
recently finished a study on simulating parcel-level urban expansion
for all Chinese cities. We have uploaded the working paper on the BCL
website as follows.

"31 Simulating parcel-level urban expansion for all Chinese cities"
http://longy.jimdo.com/working-papers-1/

Expanded 43,247 parcels during 2012-2017 in the business-as-usual
simulation scenario (BAU) for 654 Chinese cities are available online,
as The BCL Voice on Future Urban Development of China.

"20 Expanded parcels during 2012-2017 by MVP-CA"
http://longy.jimdo.com/data-released/

Abstract: Large-scale models are generally associated with big
modelling units in space, like counties or super grids (several to
dozens km2). Few applied urban models can pursue large-scale extent
with fine-level units simultaneously due to data availability and
computation load. The framework of automatic identification and
characterization parcels developed by Long and Liu (2013) makes such
an ideal model possible by establishing existing urban parcels using
road networks and points of interest for a super large area (like a
country or a continent).  In this study, a mega-vector-parcels
cellular automata model (MVP-CA) is developed for simulating urban
expansion at the parcel level for all 654 Chinese cities. Existing
urban parcels in 2012, for initiating MVP-CA, are generated using
multi-levelled road networks and ubiquitous points of interest,
followed by simulating  parcel-based urban expansion of all cities
during 2012-2017. Reflecting national spatial development strategies
discussed extensively by academics and decision makers, the baseline
scenario and other two simulated urban expansion scenarios have been
tested and compared horizontally. As the first fine-scale urban
expansion model from the national scope, its academic contributions,
practical applications, and potential biases are discussed in this
paper as well.


Hope you could find interest on it. Cheers.
