Profit and loss model of land expansion and land suitability evaluation in the villages and towns: a case study in Wudalianchi town
Land suitability evaluation is an important tool for identifying ecological attributes and potential development of lands and guiding the development rationally. Taking wudalianchi town for instance
this paper constructed seventeen factors of resistance valuation system
standing on profit and loss analysis
using RS and GIS
and applying minimum cumulative resistance model in space region
physical geography
social economy and ecological protection four aspects. The results showed: type Ⅰ(highly suitable construction region)
type Ⅱ(relatively suitable construction region)
type Ⅲ(relatively unsuitable construction region)
type Ⅳ(unsuitable construction region). The areas of these types are 41.01 km2
138.97 km2
387.85 km2 and 492.26 km2
and the percentages of these types are 3.86%
13.11%
36.59% and 46.44%. The results can provide a technology method for township construction land suitability and space regulating planning.
