2+ P
3+ P
n=1, and the Function fitness index drawing guide layer.In this case:
(1) the commerce services industry function under benefit priority guiding is selected owing to having direct correlation with the maximization of economic benefit, and therefore will include the factor of all kinds of impact exploitation income in judgement schematics in addressing, its concrete judgement schematics is:
A
1benefit priority guiding=[the comprehensive B of traffic
1] * 0.6+ [-history culture B
2] * 0.15+ [transformation difficulty B
3] * 0.05+ [-ecologic environment B
4] * 0.2
(2) the lower inhabitation function of preferential guiding of living selects to consider the effect of traffic, ecologic environment and the transformation difficulty factor, avoids the plot historical cultural resources is concentrated to develop.Its concrete judgement schematics is:
A
2live preferential guiding=[the comprehensive B of traffic
1] * 0.4+ [-history culture B
2] * 0.15+ [transformation difficulty B
3] * 0.3+ [ecologic environment B
4] * 0.15
(3) the ecological green land function under Ecology Precedence guiding is selected to consider the factors such as land present status exploitation, economic benefit.Its concrete judgement schematics is:
A
3ecology island=[comprehensive B of traffic
1] * 0.05+ [history culture B
2] * 0.25+ [-transformation difficulty B
3] * 0.1+ [ecologic environment B
4] * 0.6
Step 5: utilize GIS technology to integrate evaluation points, superposition, calculates the suitability value of difference in functionality, and carries out visual output, holds urban land potentiality with multi-angle from difference guiding.In this case, result shows:
