- Abstract:
-
The pothook of city construction land increase and rural residential land decrease is an innovative system design and arrangement. But some problems have arisen in the pilot work in recent years, many of which involve the space choice and layout planning of demolition areas and residential areas. To avoiding the randomness and risk in the choice of demolition and residential areas, and providing reference of decision-making and technical support for the standardized operation of the pothook, taking Longquanyi District as an example, a suitability evaluation index system was established to quantitative evaluation of the pothook areas. The analytic hierarchy process and multi-factor comprehensive evaluation method were also used. The results showed that: (1) in demolition areas, the region with a total score between 0.26 and 0.64 was demolition-suitable region, in residential areas, the region with the total score between 0.64 and 0.79 was residence-suitable region; (2) demolition-suitable regions mainly concentrated in the rural-urban fringe zones and suburbs in the urban edge, residence-suitable regions were mainly distributed in built-up town areas or planning areas.
