Abstract:

Taking Tunchang County in Hainan Province as a case study, dual self-organizing model accounting for geographical space as well as attribute space, was proposed. The geographic space information included the longitude and the latitude of the administrative villages. These indices such as the potential, the urgency and the feasibility were combined to construct the attribute space. The results demonstrated that the potential, the urgency and the feasibility of land reclamation were quite different among the villages. The model scores for the villages were significantly higher in the southern region than that in the northern region, and they were higher in the eastern region than that in the western region. The most desired land reclamation projects would be carried out in Poxin Town, Nankun Town, Xichang Town, Tuncheng Town. The 161 villages were divided into 6 project regions through dual self-organizing model. Based on the comprehensive score, the 6 project regions were classified into three types: priority remediation area (near-term), key remediation area (medium-term) and moderate remediation area (long-term). The area percent of three types were 25.14%, 41.83% and 33.03%, respectively. The developing orientations and suggestions for the land reclamation projects were given according to the characteristics of different influence factors. The results provide the scientific foundation in planning and implementing the project of land reclamation in Tunchang County, and is helpful in improving the level of land consolidation planning as well as promoting the land reclamation progress and the sustainable development.
