摘要: |
The term inefficient land refers to developed or built-up land that has little worth, below expected worth, or unsatisfactory utilization. It is necessary to identify the spatial pattern of inefficient land. Remote-sensing interpretation (RSI) and land-use evaluation (LUE) are mature methods used to achieve this goal, but the socioeconomic information they provide is hard to read and unintuitive. Using urban district of Zhanjiang, China, as a case, this study uses a double-aspect method (DAM), a comprehensive evaluation method, to identify the spatial patterns of inefficient land in an inner-city location. Results show that inefficient land accounted for 9.44% of the built-up land in the study area. In these areas, socioeconomic requirements were not met due to the irrational utilization of land. Land with a better location, higher worth, and fewer costs and limitations was preferred for redevelopment. The DAM was found to be more useful than RSI and LUE. Its use could help scientifically determine which urban land should be redeveloped in built-up areas similar to the urban district of Zhanjiang in international communities. |
