Optimization & control of large-scaleurban spatial form based on decision support system for land developmentintensity
2016
The paper introduced the updated decision support system for land
development intensity (version 2.0) based on the similarity relationship
between land attributes with the case of Changzhou old area as the
example. Under the improved algorithm each block selects its reference
blocks randomly in its similar blocks and the selection probability
is just the similarity coefficient between them, which leads to the
rational fluctuate interval of each pending block’s development
intensity. The outcome follows the planning decision experience and
the practical situation, which embodied the decision rationality which
also accepts the realistic chances. The planners and designers may
control the system with their urban design intensions by adjusting
the parameters such as the swing of vibrancy, reference times, difference
value, sum of development intensity, and so on. Based on this system
and a menu of typical urban block patterns under different development
intensities and land functions, the optimized procedure and method
of large-scale urban spatial form is proposed, which has the realistic
value for solving the problem of out-of-order development in Chinese
cities.
