- Abstract
Decision making for urban development strategy is a fundamental step for urban master planning. A comprehensive assessment model for urban development decision making has been tested with spatial information Tupu methodology. Taking Wusheng County as an example, an adaptive scheme for urban spatial expanding was proposed with spatially overlaying multiple influential factors. The urban development space has been split into sixteen parts by two buffer circles and eight spatial quadrants. Quantitative characteristics of land use suitability in every part were addressed and analysed with information Tupu by radar map. It is found that the appropriate development axial for short term is northeast southwest while inappropriate for northwest southeast. And for long term development, the appropriate ones are east, south and north while unfavorable for southwest and northwest. Spatial information Tupu is a new mode for analyzing urban development, which is more explainable and simpler. Spatial information Tupu has the ability to integrate different kinds of information and expresses them in a visually and quantitatively way so as to better decision making.
